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!

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?

Your diet plays a major role in the health of your heart, so eating healthy should be somewhere on the top of the list for keeping your heart healthy as well. There are numerous heart disorders that occur due to unhealthy food patterns and consumption. Lifestyle factors are the major causes of heart disease, and diet occupies an almost compelling spot when lifestyle factors are taken into consideration. Here is a list of foods that keeps your heart healthy:

Salmon: Omega-3 fatty acids are very important for your heart to function optimally. Fishes such as salmon and sardines are rich in omega-3 fatty acids which lower the risk of heart diseases such as arrhythmia (irregular heartbeat) and atherosclerosis (accumulation of plaque in the arterial walls).

Oats: Like oats and milk for breakfast!? Congratulations! You are in luck; oatmeal has soluble fibers which help in lowering bad cholesterol levels. Just make sure that there is no added sugar in your oatmeal, as it will defeat the entire purpose.

Blueberries: Blueberries are rich in antioxidants that reduce the risks of heart attack and also decrease your blood pressure. So go ahead! Toss some blueberries in your oatmeal to get your daily dose of antioxidants which are such pre-requisites for supreme health.

Dark Chocolate: This will probably bring a smile to your lips. Dark chocolates contain polyphenols, a type of flavonoid, which is very good for your heart. Dark chocolate is known to reduce the risks of strokes and heart attacks. Watch the portion size as no matter what its benefits are, dark chocolates are still rich in calories.

Citrus Fruits: Citrus fruits such as lemons and Indian gooseberry are rich in compounds that lower cholesterol levels in the body. Tip   Start your day with a lemon juice and warm water. This betters your metabolism and also keeps your heart in fine shape.

Soy: Lo Behold Vegetarians! (and non-vegetarians as well). Soy is a protein rich food that is so good for your heart. It also contains heart-healthy fats and fibers that help bring down and normalize cholesterol levels.

Tomatoes: Tomatoes are rich in an antioxidant called  lycopene , which is very effective in getting rid of bad cholesterol. It thus helps in keeping your arteries healthy and reduces the risks of heart attacks.

Nuts: Nuts such as almonds and walnuts are rich in Vitamin E which helps in lowering bad cholesterol in the body. Avoid nuts that come with added salt.

Foods That Help You Maintain A Healthy Heart

Be it burgers, bagels, muffins, sandwiches or simple toasts, bread has made headway into the diets of a huge portion of the populace. Although a staple diet for many since time immemorial, the consumption of bread has increased extensively in the recent past. But, which type of bread should we intake to incur the best health impacts is a question that bothers many. The general assumption is that the wholegrain variety is the best alternative. However, the barrage of marketing tactics makes it impossible to distinguish the best variety from the others. 

There are a whole lot of myths surrounding the best variety of bread and you must choose wisely before settling for one particular type. It is expedient to look beyond the overt appearance or the name of the bread, one needs to be wary of the ingredient before taking a call.

Mostly, white bread is made out of refined flour which is often striped off essential nutrients and fibers. To worsen the situation, white bread is often bleached with certain chemicals to enhance its appearance.
Certain assumptions deem brown bread as the healthier option. Unfortunately, it isn't true always. More often than not, brown bread is simply white bread with artificial coloring added to it or is caramelized. They essentially add no surplus nutritional value.

Similarly, multigrain bread can often mislead the consumers about its health impacts. Unlike whole wheat bread, multigrain breads are usually chemically treated with softened grains. This does not effectively recover the lost nutrients of the bread.

Whole wheat bread has more pronounced health benefits. It contains more wheat germ and fibers in comparison to the more processed varieties of bread. Having evaded the toxic additives, it has relatively healthier effects on our blood sugar levels.

As you realize that the bread that you eat does not necessarily affect your health favorably, wisdom lies in seeking out the least harmful variety. In that context, rye bread or spelt bread contains greater amount of minerals. Besides, bread made from barley, oats and millets have greater mineral content than the commercially hybridized varieties and promote better health.

Brown Bread Vs White Bread Vs Whole Grain?

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.
