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.

Coronary artery disease is the disease in which the major blood vessels (coronary arteries) that supply blood, nutrients and oxygen to your heart get damaged or disease stricken. It is mostly caused due to the coronary artery getting plagued or inflamed. The consequent reduction in blood flow to the heart causes the various symptoms of coronary artery disease like angina (chest pain), short breath etc.
Here is a list of a few symptoms that help in identification of the coronary artery disease.
1. Angina - Pressure or tightness may be felt in or near the area of the chest that results in pain. It is mostly felt in the middle or left side of the chest.
2. Shortness of breath - Another symptom of coronary artery disease is short breath, fatigue and a feeling of exertion.
3. Heart attack - Complete blockage of the coronary artery results in a heart attack that is a prominent symptom of coronary artery disease. A person may feel heavy pressure in the chest, pain in the shoulder or arm, sweating etc. prior to getting a heart attack.
Coronary artery disease occurs when damage or injury is done to the inner layer of the coronary artery. This damage causes plaque, which are deposits made of fat, cholesterol and other cellular waste materials to accumulate near the damaged area of the artery. This process is known as atherosclerosis.
The various causes that result in coronary artery damage are listed below.
- High blood pressure
- High cholesterol
- High stress
- Physical inactivity

Sir, Which type of cholesterol is leads to heart attack. Modern studies proved cholesterol is not a problem for heart attack. What is your opinion.
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.

Cardiomyopathy is a serious heart disease. It is a disease associated with the heart muscle or myocardium. In this disease, the heart muscles get weak and fails to pump blood to the organs of the body. It has several categories. The categorization depends upon the range of factors. In this disease, irregular heartbeat is observed. These irregularities can lead to heart failure or attack or can trigger problems in the valves. It is important to take care of your heart to avoid such a condition. It is also advisable to see a doctor as soon as the symptoms are noticed to avoid greater damage.
Types of Cardiomyopathy
This disease can be divided into four categories. These are as follows:
- Dilated Cardiomyopathy: It is the most common type. It occurs at a time when the heart muscle gets too weak to pump blood properly. The muscles of the heart get thinner and weak. In fact, this also leads to the expansion of the heart chambers. In common terms, it is also referred to as enlarged heart. In most cases, this is inherited or caused by some coronary artery disease.
- Hypertrophic Cardiomyopathy: This is genetically transferred to the patient. In this condition, the heart walls get thicker and this hinders the smooth flow of blood. It is one of the most common types of Cardiomyopathy.
- Arrhythmogenic Right Ventricular Dysplasia (ARVD): This is a very rare form. It can cause sudden death, especially in young athletes. In this disease, fat and fibrous tissues are responsible for replacing the muscles in the right ventricle. This leads to an abnormal rhythm.
- Restrictive Cardiomyopathy: It occurs as the ventricles of the heart get stiff and are unable to relax. This prevents them from getting filled up with blood. Under this situation, you might have to go for a heart transplant.
- Other Types: Some of the other types include Peripartum Cardiomyopathy (the one which occurs after pregnancy), Alcoholic Cardiomyopathy (happens due to excessive intake of alcohol) and Ischemic Cardiomyopathy.
Treatment of Cardiomyopathy
The treatment of Cardiomyopathy depends upon the extent of damage caused. It might not require treatment if symptoms are not very troublesome or prominent. It may be dealt with certain lifestyle changes, adjustments and medications, in cases those needs to be addressed.
Tips to deal with Cardiomyopathy
1. Maintain a healthy lifestyle by getting an adequate amount of night sleep. Go to bed early and wake up early too.
2. Don’t spend long hours in watching television or work till late night
3. Eat a lot of fresh and green-leafy vegetables daily.
4. Avoid the intake of spicy, oily and fast foods.
5. Consume home-cooked food only. Avoid eating out at restaurants or street-side joints.
6. Don’t drink excess coffee, tea or aerated drinks.
7. Don’t consume alcohol or smoke up cigarettes.
8. Don’t live a sedentary life and be a couch potato. Workout and exercise on regular basis.
9. Avoid emotional outburst and try to keep a control over your reactions. If you wish to discuss about any specific problem, you can consult a Cardiologist.
