Heart attack, also known as myocardial infarction, is a severe condition where death of the heart muscle occurs because of the loss of blood supply. The blood loss usually happens because of the blockage of a coronary artery. Due to electrical instability, ventricular fibrillation is caused. Heart attacks may result in permanent brain damage or even death.

Symptoms of heart attack
There are many early symptoms and signs of heart attack, which should be recognized. Symptoms of heart attack vary from person to person. Here is a list of the primary heart attack symptoms:

Chest pain and discomfort:
Chest pain is the basic symptom of a heart attack and occurs in different forms. The chest pain has a pressure, fullness and squeezing sensation and starts from the center of the chest. The pain may go away and re-occur and may spread down to other limbs of the body.
Headache, toothache:
The chest pain occurring due to a heart attack spreads all over the body and the jaw. Even the back and head are affected. Sometimes pain in these regions is present while chest pain is absent.
Shortness of breath:
A gasping sensation or feeling shortness of breath is another common sign of a heart attack. Such breathing difficulty is called dyspnea. The shortness of breath occurs before or during the chest pain.
Nausea and vomiting:
The feeling of nausea or sickness in the stomach is another possible symptom. It is accompanied by belching or burping and sometimes, the heart attack is associated with a feeling of indigestion. Nausea is more common in women. Vomiting also occurs alongside nausea.
General epigastric discomfort:
In several cases, patients describe the pain of a heart attack as stomach pain. The pain is heavy and uncomfortable and persists for several minutes.
Sweating:
Perspiration or sweating occurs during a heart attack and the patient experiences cold sweat in avid amounts.

Emergency treatment for heart attack-
A person who has a heart attack should be rushed to a hospital.
Several tests are carried out to detect the cause of the attack. A 12 lead ekg is carried out to supervise electrical activity within the heart and detect the damaged areas.
Blood tests are undertaken to check enzymes and in certain cases, cardiac catheterization is required where pictures of the blood vessels are examined.
Emergency medicines are given to the patient to stop the formation of blood clots and include aspirin, heparin and other drugs. Other medicines are given for thrombolytic therapy, which dissolve already formed blood clots. They work to reduce the heart damage. Nitrates are also used.

A heart attack is a severe condition and must be attended to immediately. Emergency treatment procedures are essential to save the life of an affected person.

Heart Attack - Signs, Symptoms and Emergency Treatment

What Happens When the Electrical Activity of Your Heart Changes?

The heart's electrical conduction system plays a very important role in cardiovascular functioning. Also known as the atrioventricular (AV) conduction system, it regulates and controls the timing of the heartbeat.

How does the heart's electrical conduction system work?

There is a collection of electrical cells in the upper right atrium of the heart known as the sinoatrial (SA) node which acts as a natural pacemaker and generates electrical signals. These signals travel through specialized electrical pathways and stimulate the muscular walls of the heart to contract in a rhythmic manner. This gives rise to the heartbeat that pulses at a specific frequency every minute.

What is the effect of fluctuations in electrical activity on the heart?

The standard heart rate in human being ranges from 60 to 100 beats per minute. It slows down when a person sleeps and speeds up when one experiences physical or emotional heightening. These fluctuations are triggered by the brain or other systems of the body and signal the SA node to generate charges more rapidly or slowly. This leads to spikes and drops in the heart rate, depending on the nature of the situation.

What happens when there is dysfunction in the heart's electrical activity?

When the heart's electrical conduction system does not function properly, it leads to the occurrence of a condition known as arrhythmia or abnormal heart rhythm. This happens when electrical impulses are generated in an irregular manner and causes tachycardia (rapid heartbeats) or bradycardia (slow heartbeats) which takes place in jarring infrequent tempos.

What causes fluctuations in the heart's electrical activity?

There are various kinds of triggers that cause the heart rate to fluctuate. The exact nature of fluctuation also depends on the type of trigger. A few everyday examples of these causes are as follows:
- Exercise and strenuous physical activity increases electrical activity as the heart is required to beat faster so as to increase the supply of blood and oxygen to the muscles.
- Sleep and rest reduce heart rate as the body is not needed to exert itself.
- Release of adrenaline into the bloodstream causes the heart rate to spike up.



What Happens When the Electrical Activity of Your Heart Changes?

What is Palpitation?
Palpitation is a feeling of awareness of your own heart beat. It is usually described as heart rate being either too fast (racing), too slow or a sensation of missing a beat.

Types of palpitations?
Normal (Benign)
- These palpitations occur as a response to physical or mental stress like exercise, fever, pain, fear, anxiety etc. 
- They are harmless and settle on their own once the precipitating factors disappear. They do not require any medical treatment.

Abnormal
- These palpitations occur due to some underlying abnormality in either the structure of heart or the beating of heart. 
- These can be dangerous and at times life threatening. They may or may not settle on their own and require some medical treatment.

Warning signs that suggest palpitations are abnormal?
Palpitations are abnormal, if they are associated with chest heaviness, chest pain, uneasiness, sweating, weakness, giddiness, feeling of black out, fainting, nausea, vomiting, seizures. Palpitations are more likely to be abnormal in people who have some existing heart disease and these patients should report to their doctor at the earliest.

What to do during palpitations?
1. Stay calm. 
2. Call for help. If u are alone avoid driving, use a taxi or auto, go to your nearest hospital/doctor and try to get an ECG during the palpitations. If you are helping someone having palpitations, if they faint, call for help, start CPR if they remain unresponsive and take them to the nearest hospital. 

Which doctor can treat palpitations?
Doctors who specialise in the treatment of palpitations are called Electrophysiologists. They specialise in heart rhythm and are capable of performing a variety of complex tests to identify and treat different types of palpitations.

Which investigations are used to diagnose palpitations?
ECG: Taken during palpitations and when the patient is normal is a very helpful tool. 
Holter: Externally applied recorder, which continuously records heart rhythm for 24 hrs. 
ELR: Extended loop recorder, is like holter, but it records rhythm for longer durations. 
ILR:  Internal loop recorder is attached within the body for recording rhythm for long duration. 
EPS: Electrophysiology study, is the most sure shot test to diagnose, identify and treat 
Palpitations.

What is EPS?
EPS stands for Electrophysiology study. By this test a trained Electrophysiologist studies the conduction and formation system of heart beat, to understand the source, cause and type of palpitation. It is a simple and safe procedure of 2 to 3 hours and can be done as a day care procedure (by admitting the patient for a few hours in hospital, with discharge on same day).

It requires fasting for 4 hrs, some standard blood investigations and is done with local anaesthesia and if required it can be combined with treatment like ablation in the same sitting.In the procedure Electrophysiologist take catheters into your heart to study and stimulate the palpitations and understand them. Once found they can use various techniques to stop the palpitations, the techniques are called Ablation.

What are the treatment options available for palpitations?
There are many options depending upon the nature of palpitations and condition of the patient: 
- Drug therapy 
- Cardioversion where either a drug or electric shock is given to stop palpitations immediately. 

Ablations using many sophisticated computer softwares 
Device Therapy like ICD (Internal cardiac defibrillator) 
Combination of all the above therapies.

Your Electrophysiologist and you as a team can make a choice about the options that will be best for you.

Palpitations - Everything You Need to Know

Cardiac or Heart Arrhythmia is a condition which results in disruption of heart s normal rhythm. Due to this, the heart may beat too quickly, too slowly or have an irregular rhythm. Though most of the arrhythmias are not harmful but at times they can have serious consequences, which might turn to be fatal. Differences in heart beats can lead to the restriction of blood, that gets pumped around the body, hence causing damage to the brain, heart and other organs of an individual.

Now we would take into account the causes behind the occurrence of this heart condition.

Causes

Interruption to the electrical impulses in any form that lets the heart to contract can result in arrhythmia. A person with a healthy heart should have a heart rate of anywhere between 60-100 beats per minute while the body is at rest.

There are a number of factors which can cause the heart to work inefficiently, which include:

Alcohol Consumption: If you are used to drinking alcohol varying from light to moderate, the chance of irregular heartbeat increases. A recent study has shown that with every drink consumed per day, the risk of atrial fibrillation increased by 8 percent. Men and women both are at equal risk for irregular heartbeat. Irregular heartbeat is caused because drinking leads to damage of the cells, which in turn leads to causing damage in small areas of fibrous tissue within the heart.

Anxiety: Arrhythmia from anxiety is when the heart feels like something happened due to which it tries to overcompensate and beat quickly. This leads to heart skipping a beat, getting squeezed or undergoing heartbeats at a rapid pace.

Excessive Cosumption of Coffee: Caffeine is a stimulant and tends to speed up heart rate, so consuming too much coffee can lead to the problem of arrhythmia.

Deficiency of Magnesium and Potassium: Magnesium and Potassium deficiencies in one s body can cause Arrhythmia. The deficiencies can be caused due to less intake of citrus fruits and vegetables like potatoes, kiwi, papaya etc.

Symptoms

Arrhythmia can produce a broad range of symptoms which affect the proper functioning of heart. Some of the most serious symptoms are:

Fatigue: If you feel that you are getting fatigued quite easily, then it s a clear symptom of arrhythmia.

Dizziness: A sense of dizziness creeps in when you are having the problem of irregular heartbeat.

Lightheadedness: Feeling light on the head is another symptom of Cardiac Arrhythmia, as there is fluctuation in the amount of blood that reaches the brain through the heart.

Treatment Options

Problem of irregular heartbeats, especially if it s on the slower side, can be solved through the placement of certain devices like pacemaker, which can speed up one s heart rate.
Faster heartbeats can be treated through blood-thinning medications, which would help keep threatening blood clots from getting formed.
Doctors can even go for Catheter ablation, wherein they would thread one or more catheters through the blood vessels of one s heart. Electrodes at the catheter tips can make use of extreme heat, cold or radiofrequency energy to damage a small sport of heart tissue and create an electrical block along the path, that s causing one s arrhythmia.

5 natural ways to control your blood pressure

Blood pressure rises with each heartbeat and falls as your heart relaxes. The normal blood pressure should be less than 120/80 mm hg. An increase or decrease on either end can cause various problems.

Here are some of the natural ways to control your blood pressure.

1. Having a diet low in sodium

In the event of a high blood pressure, curtail the consumption of foods that are rich in sodium. However, research reveals that sometimes it is not just enough to cut down on sodium in your diet. A person suffering from high bp should consume foods rich in minerals like calcium, magnesium and potassium as well to keep his/her bp in check.

2. Drink plenty of water and curtail the consumption of alcohol

In case a person suffers from low blood pressure, it is advisable to drink plenty of water as low blood pressure is usually accompanied by bouts of dehydration, and consumption of water can help increase your blood pressure. Also, health drinks, which are rich in electrolytes, help your raise blood pressure. But one should avoid drinks that are high in sugar, and abating your alcohol consumption also helps to quite an extent.

3. Burn extra calories and exercise regularly

Blood pressure usually increases with weight. Being overweight can lead to sleep apnea, which is marked by disruptive breathing while you sleep, which in turn condition can lead to increased blood pressure. Studies have found that weight loss is one of the most effective ways to control high bp. Regular physical activity is also advised to maintain a stable blood pressure.

4. Avoid long, hot showers

The hot water in showers and spas can expand your blood vessels, which can often lead to a drop in blood pressure. A common sign of this would be dizziness and fainting while taking a bath. Therefore, for people suffering from this condition, using warm water rather than hot water is advisable.

5. Completely avoid stress

One of the contributing factors of high blood pressure is chronic stress. Stress tends to affect blood pressure in indirect ways. Many react to stress by overeating, consumption of alcohol and smoking, all of which can increase your blood pressure. Try to know what triggers your stress and take steps to avoid it.

5 Tricks that Control Your Blood Pressure, Naturally

With recent lifestyle changes, more and more people, younger in age, are falling prey to heart attacks. While some silently suffer the attack during their sleep and never wake up, others have symptoms which they dismiss as acidity or muscular pain and ignore them. There are multiple media programs that are trying to create awareness about how to identify a heart attack. If done at the right time, there is a good chance that the person can be saved.

What is a Heart Attack?

The blood vessels gradually narrow, reducing the blood flow to the target organs. This reduces the efficiency of the target organ, and if this happens to be the heart, it is known as a heart attack. The area that should ideally receive blood does not, leading to its  death.  If the damage is not severe, it can be reversed. However, if this attack happens in one of the critical areas of the heart, it can even be fatal.

Symptoms To Watch For: Very few attacks happen suddenly. Most start slowly and progress, and if identified on time, a life can be saved. The episode takes about an hour, and if you are well-versed with the symptoms, it could help identify the condition correctly and save a life. Most people use antacids and muscle relaxants to ease the situation, which does provide immediate relief, but not a proper cure.

There is a central pain which is constant, nagging, and has a squeezing like sensation. This causes discomfort and most often, this pain is in the center of the chest area, which lasts for just a few minutes. Sometimes the pain can go and come back. This pain radiates down into the arm, up into the neck area, and also into the jaw and is almost always indicative of a heart attack.

With chest pain, there is always shortness of breath which the person will experience. This is due to reduced oxygen levels in the body.

Associated symptoms include fatigue, exhaustion, nausea, dizziness, light-headedness.

There is almost always profused sweating where the person breaks into a cold sweat.

If the attack happens during sleep, the person may be snoring and may feel, as if something is choking his airway.

Due to reduced return of blood from the peripheral organs, there could be swelling of the feet and ankles.

If there is irregular heart beat (palpitations) very often, talk to your doctor about it.

When you suspect a person of having a heart attack, check for these signs. Very often, a heart attack is detectable and can be managed with timely intervention.
