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.

Beetroots are packed with nutrients and can be eaten raw, pickled or cooked. Beetroots can even be juiced. It has been used in a number of sweet and savoury recipes. When it comes to beetroots, the root as well as the leaf can be eaten. Here are a few great reasons why you should eat beetroot.

    It's good for the heart: Beetroots are rich in nitrates. This helps relax the arteries and reduces blood pressure. Being rich in fiber and antioxidants enables beetroots to prevent plaque formation in arteries. The antioxidants in beetroots also prevent bad cholesterol from being deposited on the artery walls. Thus it protects against heart attacks and strokes.
    It helps fight diseases: Beetroots are said to boost immunity and fight a number of diseases including cancer, Alzheimer's and liver disorders. Beetroot is rich in betanin that expels cancer triggering agents and prevents the development of tumours on both the skin and liver. It is also said to protect a person from breast cancer. It also helps detoxify the body.
    It helps build strong bones and teeth: Beetroots are rich in silica. This silica is a crucial component required for healthy bones and teeth. Along with silica, beetroots are also rich in magnesium, vitamin C and folate. Beetroots also help prevent osteoporosis.
    It helps control blood sugar: Beetroots are naturally sweet, but can help control blood sugar and help fight diabetes. Beetroots are also rich in soluble fibers that can help regulate blood sugar levels. Drinking beetroot juice thrice a week is the best way to use beetroots to stabilize glucose levels in the body.
    It aids in weight management: Beetroots have a very low calorific value and are rich in fiber. This makes it an effective tool in weight loss. It also helps rid the body of toxins and excess water.
    It slows the aging process: Beetroot adds a glow to your skin. It helps cleanse the blood of toxins and thus makes skin healthier. The anti oxidants in beetroot reduce free radicals and thus slow down the aging process. This pink vegetable also has anti septic and anti inflammatory properties that help heal skin.
    It makes hair healthier: Carotenoids in beetroot give hair a lustrous shine and help fight hair fall. Beetroots are also rich in protein, phosphorus and a number of other vitamin and minerals essential to healthy hair. It helps improve blood circulation in the scalp and helps remove dead skin and excessive oil from the scalp.

6 Things that make you prone to heart diseases the most

Every year almost 2 lakh people opt for heart surgeries in India; and as of 2015 there were about 30 million people in the country suffered from heart diseases. There are several factors that increase the threat of heart diseases, among which some can be controlled and some can't. On one hand, where factors like being a man, old age, being a woman in the post-menopausal phase of life, and a family history of heart diseases are beyond your control; other risks can be minimized by making some lifestyle changes. 

Although natural processes like ageing, which narrow down your arteries and weaken the heart muscles increase the risk of heart diseases here are 7 factors, which dramatically increase your chances of getting heart diseases, while you are still young.

1. Genetic Factors: 
If someone in your family is already suffering or has suffered from a heart disease, especially at a young age, it increases your probability of getting a cardiovascular disease.

2. High Levels of Cholesterol in the Blood:
Chances of formation of plaque on the inner walls of the arteries increase with increasing levels of bad (LDL) cholesterol in the blood. This may be a major cause of the heart disease, atherosclerosis, which happens due to accumulation of fatty substances inside the arteries. 

3. Smoking:
Smoking causes constriction of your blood vessels and may damage their inner lining due to the effect of nicotine on them. This can put you at high risk of developing atherosclerosis. Moreover, studies suggest that people who smoke are twice as prone to heart attacks in comparison to non-smokers.

4. Hypertension:
If your blood pressure level is usually above normal, it can give rise to thickened arteries, which, in turn, can reduce the passage for the flow of blood through the vessels. This damages your heart health to a large extent and makes you prone to heart diseases.

5. Diabetes:
Uncontrolled diabetes increases your chances of getting a heart attack, especially because diabetes almost goes hand in hand with diabetes and obesity, which are risk factors of heart diseases.

6. Stress:
If you fail to keep your levels of stress and anger in check, they may have a damaging effect on your arteries. This can make way for strokes and heart attacks in the future.



The 6 Things that Make You Prone to Heart Diseases the Most

A heart attack does not always have obvious symptoms, such as pain in your chest, shortness of breath and cold sweats. In fact, a heart attack can actually happen without a person knowing it. This condition is known as a  silent heart attack , medically known as  silent ischemia , occurring due to the shortage of oxygen supply to the heart muscle. The causes of a silent heart attack are similar to that of a heart attack. 

They include- 

Conditions like: 
Obesity or excess weight 
Diabetes 
High Blood pressure 
High cholesterol 
Heart Diseases 
Lack of exercise 
Age, usually above 65 
Consumption of tobacco or smoking 
High consumption of alcohol 
A silent cardiac arrest makes one more vulnerable to another heart attack that could be fatal. Diagnosis: The only method to diagnose if you had a silent heart attack is through imaging tests, such as echocardiogram, electrocardiogram, Holter Monitoring or others. These tests can show certain changes which might be indicative of a heart attack. An analysis of one s overall health and the symptoms can aid in deciding whether few more tests are required. 

How would you prevent a silent heart attack? 
1.   Get your cholesterol and blood pressure count tested regularly. 
2.   Refrain from smoking. 
3.   Get your VO2 max checked regularly. 
4.   Live a healthy lifestyle: Refrain from smoking and excessive alcohol consumption; exercise daily, eat healthy. 
5.   Control high blood pressure, cholesterol, and diabetes 
6.   Be aware of your body and call on a doctor if you feel there s anything which is bothering you. 

If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.

Know Everything About Silent Heart Attacks

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.
