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?

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. 

Cardiac Arrest And Heart Attack - Understanding The Difference Between The Two!

On an average a person consumes nearly 800 calories daily from added sugar. This does not just include natural sugar found in fruits or milk but the processed sweet sugar as well, that is added to cakes, tea, coffee, confectionery and even pasta sauce and salad dressing. However, it is possible that you can limit your sugar intake or even quit it to get some truly amazing benefits.

When you take this hard decision, you may experience withdrawal symptoms such as mild depression, anxiety or restlessness. But if you remain adamant and continue with your decision, your body will soon show some incredible results that you couldn't have imagined.

Here are a few of them:

1.&nbsp;Your heart will beat happily

Sugar raises insulin levels that activate the responses of sympathetic nervous system thereby elevating your bp and heart rate. When you cut down on sugar, your ldl cholesterol will decrease by 10% and triglycerides will reduce by 20-30%. And your risk of heart attack will reduce manifold.

2.&nbsp;Your weight fluctuations will be gone

With the exception of fruits, sugar is mostly present in processed or high-carb foods that contain loads of other unwanted constituents like fat etc.

So when you quit sugar, your body has to no longer worry about those unwelcome calories and your weight will stop moving right and left across the scale.

3.&nbsp;Digestion will become efficient

When you quit sugar, the digestive system becomes more efficient. Since your stomach and intestines have to no longer worry about those difficult to digest processed foods, their abilities and functioning improves. Even your colon begins to work better, may be you take more trips to the restroom, so things get even more on track.

4.&nbsp;No more acne troubles

Sugar triggers acne troubles. When you cut it down, you will no longer be troubled by those zits that dampen your looks. Your skin will actually clear up, cracks will disappear and you will get a healthier skin.

5.&nbsp;You will no longer have sweet craving

With sugar, there is a huge negative, as you enjoy sweets, you crave for more sweets. But if you quit sugar, slowly you will begin to avoid foods that contain sugar and as a result, whenever you will eat anything that has sugar, it will taste over sweet and you will not be able to have large portions. This means no more cravings for sugar!

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

Bradycardia is a condition which in basic terms means slow beating of the heart. In most cases, the typical rate is 60 to 100 beats in a minute when the person is at rest. In case your heart beats less than 60 times in a minute, then it is slower than normal. But a slow heart rate is not always a health concern even though sometimes it could indicate issues with of the heart.

What could bradycardia mean?
Some people with slow heart rate or bradycardia tend to be very fit, and they have no underlying health issues. Athletes and healthy young adults often have a heart rate lower than 60. But in others, bradycardia indicates that the natural pacemaker of the heart is not working well, or the electrical pathways have been disrupted. In severe forms of the problem, the heart may beat so slowly that it fails to pump adequate blood for meeting the needs of the body. This may show some symptoms and could be fatally dangerous.

What are the causes of bradycardia?
There are various causes of bradycardia, and some of them include:

Alterations in the heart which results from aging
Health conditions that slow down the electrical impulse through the heart. This may include electrolyte imbalance, low thyroid levels, and others.
Diseases which may disrupt the electrical system of the heart including heart attack, coronary artery disease, and myocarditis.
Certain medications that are used for treating heart problems like high blood pressure or hypertension, arrhythmia, and beta-blockers, and digoxin.
What are the symptoms of bradycardia?
When a person has very slow heart rate, he or she may experience lightheadedness or dizziness, feeling short of breath, having difficulties in doing normal activities or exercising, having chest pain, feeling tired and fatigued. In some cases, it is seen that the person may have palpitations, feeling confused, trouble in concentrating and fainting.

What s worse, some people don t have any symptoms at all, or their symptoms are so negligible that they think they are caused just because of aging. The best way to understand whether you have this problem is to take the pulse, and in case, it is slow or uneven, you must talk to a doctor.

How is bradycardia diagnosed and treated?
Bradycardia tends to come and go from time to time, and therefore, a standard EKG is not always able to detect it. A standard ambulatory electrocardiogram is used for detecting the condition, and sometimes, blood tests are also necessary.

The treatment of bradycardia is entirely dependent on the cause of the problem and its symptoms. It is worthy of mention here that in case the problem is not causing any symptoms, then they would not be treated under usual circumstances.

An Effective Guide To Bradycardia!

Automatic Implantable Cardioverter Defibrillator is an electronic device that is located in the chest of the patient suffering from arrhythmia. Arrhythmia is a condition which causes abnormal rhythm of heartbeat in the patients. It is a life-threatening condition. The device is located in the chest to correct the rhythm of a heartbeat.

AICD device works in two ways:

Firstly, it tries to correct the abnormal heartbeat rhythm and release high- speed heartbeat pace. This is called cardioversion. Patients with AICD generally do not feel the process.

However, if the effect of cardioversion is null then the device will give a mild electric shock to the patient's heart to correct arrhythmia and reset the rhythm.

This second method is called defibrillation. The patient can feel the defibrillation.

The modern-day AICD device is programmed to store the data about the patient s heart rhythm. Doctors use the programmed device which contains your condition and provides medically correct therapy.

Preparation for AICD Implantation

The patient is required to fast six hours before undergoing the surgery. On admission, prescribed medicine is given to the patient and the latest heart condition is measured by an ECG test. If the patient is on blood-thinning medication, then it will be stopped 24 hours before the surgery.

The procedure will be carried out by a cardiologist. The patient will remain under observation in the hospital for at least two days.

Procedure

The entire process of setting up the device in the chest of the patient takes about 2 hours. The patient is sedated, and the area below the collarbone is numbed for the operation. A small incision is made in the chest area. With the help of imaging techniques, cardiologist sets up the device in the chest. The device is then connected to the veins and the heart. After the surgery, the patient is kept under observation. Heart rate, blood pressure, and overall health condition are observed by the doctors to determine successful implantation of Automatic Implantable Cardioverter Defibrillator (AICD). Post Procedure After the successful recovery of the patient, doctors usually discharge the patient with AICD attached. The doctors give complete care instructions of the device along with health. Doctors also guide the patient through the list of activities that one can and cannot perform. AICD is a life-saving device. Hence, proper care and regular check-ups are recommended by the doctors. The regular check-up of the device is also essential since the device runs on a battery. The doctors also train the patient about the workings of the device. They will also explain about the mild shocks of the device one may receive to correct the arrhythmia. Before leaving, make sure the site of the surgery is dry and healing, and you do not have a fever for the past 24 hours.

AICD Implantation - Know Procedure Of It!

Loving relationships are known to improve more than just your mood, it improve your looks and your health. Researchers believe that it might just be the best medicine for most people, as it helps keep your heart healthy, beat cancer and recover faster, boosts athletic performance and leads to spiritual and emotional growth. Mentioned below are a few of the ways, in which love may lead to a healthy heart and life. 

1. Better heart health: research has shown that women in healthy and loving marriages are less prone to contracting cardiovascular diseases, in contrary to those in stressful marriages. It has also been discovered that love reduces the likelihood of chest pains and suffering from angina despite having high blood pressure, high cholesterol and diabetes in men.

2. Lengthens your life: the national longitudinal mortality study studied a million subjects and concluded that couples in a loving marriage tend to live longer and have lowered risk of getting heart attacks, pneumonia, cancer and cirrhosis of the liver. Their chances of committing suicide are also reduced by almost half.

3. Faster cancer recovery: after extensive research, university of iowa proved that patients of ovarian cancer, who were in loving relationships, had stronger wbcs i. E. White blood cells that kill cancerous cells, as compared to those in unhealthy relationships. They also concluded that patients in love recover quickly or completely eliminate cancer. 

4. Lowers blood pressure: studies show that when couples are together, their blood pressure is significantly lowered. This research even proved that spending time with loving and supportive friends results in lower systolic numbers. 

5. Keeps you slim: being in love is a much healthier and better option than juice cleanse, when it comes to losing that extra weight. People in loving relationships produce more adrenaline i. E. An appetite suppressant and are more likely to hit the gym and make healthier lifestyle choices to look their best. Apart from that, sex is one of the best ways to lose calories and reduce your weight.
