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.

Having bradycardia implies that your heart beats very slowly. For the vast majority, a heart beats from sixty to hundred pulses a minute while very few are viewed as ordinary. In case your heart beats under sixty times each minute, it is slower than usual. A moderate heart rate can be ordinary and solid. On the other hand it could be an indication of an issue with the heart's electrical framework.

For a few people, moderate heart rate does not create any issues. It can be an indication ...more

Atrial fibrillation is a condition that results in rapid heartbeat leading to heart failure, stroke, and other cardiac complications. In this condition, the upper valves of the heart beat irregularly. Some of the common symptoms of this condition include weakness, heart palpitations and shortness of breath. There could be several episodes of Atrial fibrillation. Although it is not life threatening, there could be serious complications owing to the nature of the condition. Atrial fibrillation can...more

A sudden cardiac arrest is not same as a normal heart attack. While a heart attack refers to the blocking of blood flow to the heart, a sudden cardiac arrest refers to when the heart stops beating unexpectedly. Sudden cardiac arrests occur without warning and often this condition is triggered by electrical malfunctioning in the heart that causes arrhythmia. When the heart stops beating, blood cannot be pumped to the brain and other organs and the person loses consciousness. If a patient does not...more

Are you experiencing irregular and fluctuating heartbeats? Is your heartbeat too fast or too slow? If yes, then it signifies that you are suffering from arrhythmias or abnormal heart rhythms. This is a disorder which affects the heart rate or heart rhythm and the heartbeat becomes irregular.

Causes of abnormal heart rhythms
Arrhythmias occurs due to problems with the electrical conduction system of the heart. In this case, abnormal signals might occur; the electrical signals might g...more

Cerebral ischaemia or brain ischemia is a medical condition that restricts the flow of blood to the brain, resulting in an unmet metabolic demand. This leads to limited oxygen supply in the brain, which could result in death of brain tissues, cerebral infarction or an ischemic stroke. Thus, a cardiorespiratory arrest, a stroke, and irreversible brain damage are few possible consequences of cerebral ischaemia.

The heart is a muscular organ and beats at regular intervals. This is known as heart rate, which indicates a person s overall health. In a normal healthy individual, it ranges from 60 to 100 depending on overall health status. A heart rate outside of these ranges is usually a cause for concern.

Bradycardia is when the heart rate is below 60. While this could be a sign of fitness and health in some, it could also mean an underlying cardiac condition in others. Low heart rate is seen in m...more

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...more
