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?

Is your child getting exhausted after a bout of cough? Does he or she suffer from constant wheezing and tightness of the chest? Does your child feel drained out after climbing a flight of stairs? Do you know a child who always seems to run out of breath and cannot participate in school sports tournaments or play outside for a long time? The child could be suffering from asthma, which is a serious breathing problem. Most children are affected by asthma. Staying in a polluted city just makes the condition worse.

Asthma - Know the disease

Asthma is a condition that causes inflammation of the airways, known as trachea and bronchioles.
The muscles around the airways constrict and prevent the smooth flow of air.
The lining of the bronchioles swell and block the airways.
Asthma is mostly triggered by an allergic reaction.
There is a difficulty in breathing out. Exhalation of air is often accompanied by a wheezing, that is, a whistling sound.
There is a constant shortness of breath, feeling out of breath and gasping for air.
There is an uncomfortable tightness in the chest, the feeling of not breathing in enough air.
Coughing bouts in the middle of the night, that leave the child feeling exhausted and completely out of breath.
Causes of Asthma 

Asthma is mostly triggered by asthma allergens. These allergens are mostly pollens and animal fur.

Exposure to pollution, such as dust and smoke
Heredity
Obesity
History of heartburn, GERD and acid reflux
Inflammation of sinus and airways
History of bronchial disorders and pneumonia
Viral infections
Chronic rhinitis
Low immunity causing constant cold and blockage of nose
Treatments of asthma

A nebulizer that turns asthma medicine into a mist can then be inhaled easily
An inhaler can be used to take in inhaled steroids into the lungs or a bronchodilutor
Try and avoid asthma triggers and allergens as much as possible
Avoid physical stress and heat
Get sufficient rest of about 7-8 hours every day

Troubled Breathing - Can It Be a Sign of Asthma?

The news of Sridevi's sudden and unexpected demise was a shock for the entire nation and left a number of questions in the minds of the people. However, there are multiple reasons which are under speculation and can be attributed to her death - cardiac arrest, heart attack and death due to accidental drowning. Usually, cardiac arrest and heart attack are two things which most people use interchangeably, however, there is a big difference between the two. 

Difference between cardiac arrest and heart attack: 
A cardiac arrest is far deadlier considering that it comes without a warning or any prior indication of a problem. Here, the heart just stops beating and immediate first-aid can make a lot of difference between life and death. Electrical shock is the best way to revive a patient and should be given within a few minutes of such an arrest. 

On the other hand, a person suffers a heart attack when there is a blockage in the artery which prevents the smooth flow of oxygen-rich blood from reaching the heart. It is important to note that unlike a cardiac arrest the signs of heart attack start slow and persists for long. 

A heart attack is one of the common causes of cardiac arrest, but not always it is the case. A cardiac arrest happens most commonly when the heart is receiving more than 300 impulses per minute or due to absent electrical impulses. In the first instance an electrical shock is a lifesaving technique and in the second, the patient can be treated with certain medications and a temporary pacemaker. 

Symptoms of cardiac arrest:
The symptoms of cardiac arrest are immediate and extreme.

A fainting spell or a sudden collapse
Loss of consciousness
No pulse or breathing 
Symptoms of a heart attack 

Discomfort along with chest pain 
Shortness of breath
Nausea with vomiting
Sweating
Headache and jawpain
Prevention of a cardiac arrest:
What makes this a deadly condition is that you cannot tell your risks of having one and therefore the next best thing to do is to lower your risks. 
The best way to do that is to:

Follow a diet that is balanced and nutritious
Alcohol should be consumed in moderation 
Quit smoking
Stay physically active
How can you prevent a heart attack?

Keep yourself fit and exercise regularly
Keep your cholesterol level under check 
Limit your alcohol intake 
If you are obese, control your weight
Intake a heart-friendly diet.
Now that the distinction is clear between the two, it is recommended that everyone should get themselves screened for potential heart problems on a regular basis. In case of a query or concern consult an expert and get your answers.

5 Wonderful Things That Happen to Your Body When You Quit Sugar!

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.

Signs Of A Heart Attack

High cholesterol has become a very common phrase nowadays. With excessive consumption of fast foods and sugar, lifestyle disorders such as diabetes and high cholesterol have become very common. In order to know what high cholesterol is, you should first know about cholesterol.

Cholesterol is a type of fat present in the body which is needed for regulating hormones in the body. It also plays an important role in Vitamin D production. Though you get cholesterol from food, the body has its own supply of cholesterol as well. Excessive cholesterol in the body can lead to cholesterol build up in your arteries, resulting in blood circulation problems. The arteries tend to narrow down, not allowing the blood to flow properly. High cholesterol levels are linked to heart problems and strokes.

Ayurveda is a holistic system of medicine, the treatments of which are based on natural ingredients. It is very effective and free from side effects, unlike conventional methods of treatment. Ayurvedic remedies for high cholesterol levels in the body aim to bring down the cholesterol level and improve your overall wellbeing.

The Ayurvedic tips to lower cholesterol levels are:

Eat healthy: Diet plays an important role in maintaining healthy cholesterol levels, so eating healthy is of paramount importance. Include plenty of vegetables and fruits in your diet to get the required amount of Vitamins and minerals in order to keep your body healthy. Avoid refined grains as they spike your blood sugar levels. Instead opt for whole grains such as brown rice.
Eat healthy fats: Eat healthy fats such as unsaturated fats present in foods such as almonds and olive oil. Keep saturated and trans-fats at bay as they increase cholesterol levels in the body.
Exercise regularly: Regular exercise keeps your weight levels optimal and also brings down your cholesterol levels. Simple cardiovascular exercises such as running and swimming can be done on a regular basis.
Avoid smoking: Smoking causes your blood vessels to constrict, thus hampering the flow of blood. In addition to accumulation of plaque, this can further hamper blood flow.
Maintain optimal weight levels: Following healthy eating habits along with regular exercise will allow you to maintain optimal weight levels. So if your weight is on the higher side, then re-evaluate your eating habits and make the necessary changes. If you wish to discuss about any specific problem, you can consult an Ayurveda.
