Atrial flutter is usually a precursor to the development of atrial fibrillation. This usually occurs in patients who underwent a heart surgery.

Atrial flutterĪn atrial flutter also causes abnormal contractions in the atria but these contractions are more organized and regular than atrial fibrillation. In this type of arrhythmia, the upper chambers of the heart or the atria are contracting in an abnormal manner. It is often described as the skipped heartbeat that is experienced occasionally. This is considered to be the most common type of arrhythmia that may occur in people even without a heart disease. The occurrence of this is usually harmless and do not require any treatment. Įlectrical impulses in the atria cause some extra early beats. There are different types of arrhythmia depending on the changes in the rhythm. Any irregularity in the heartbeat is known as arrhythmia and it can be caused by different factors. It is the atrioventricular node (AV node) found in the ventricles that send the electrical impulse for it to contract.

The sinoatrial node (SA node) is responsible for the electrical impulses that make the muscles in the atria to contract. There is an electrical system within the organ that powers it and puts out pulses in a regular rhythm. There are 4 chambers in the heart: the atria and the ventricles. Many of the changes in the heart rate are minor and usually do not require medical attention but if this condition persists for a long time, it can be a sign of a medical condition. The normal heart rate for an adult is between 50-100 beats per minute and the rate is higher in children. The heart beats in a regular rhythm at a rate that is appropriate for the body’s work at that particular moment. If this is caused by another medical condition, it should be managed immediately to avoid the development of complications. The irregularity of the heartbeat are typically harmless but it can be a symptom of an underlying medical condition. Irregular heartbeat is people may sometimes feel that their heart beats too fast or too hard.
