The condition is caused by a single electrical impulse that travels rapidly in the affected atrium.

However, it may occur in the left atrium as well. Atrial flutterĪn atrial flutter (AFL) typically occurs in the right atrium, which is one of the two upper chambers of the heart. It can elevate your heart rate to 100 to 200 BPM, which is a lot faster than the normal 60 to 100 BPM. It’s the most common arrhythmia.Ītrial fibrillation, or AFib, occurs when many unstable electrical impulses misfire and may result in the atria quivering out of control.ĪFib causes the heart rate to increase and become erratic. This disorganized heart rhythm occurs in the upper chambers of the heart. With sinus tachycardia, your heartbeat returns to normal once you get better or become calm. Sinus tachycardia is a normal increase in the heart rate that may occur when you’re sick or excited.Ventricular tachycardia occurs in the lower chambers known as the ventricles.Supraventricular tachycardia occurs in the upper chambers of your heart known as the atria.Tachycardia is any resting heart rate over 100 beats per minute (BPM). For example, a normal heart beats 60 to 100 times per minute in adults. Tachycardia means that your heart is beating too fast. The most common types of abnormal heart rhythms are: Tachycardia But to be on the safe side, you should report any abnormal heart rhythm to your doctor. Not all arrhythmias are life-threatening or cause health complications. If the functions of this vital system are disrupted, damaged, or compromised, it can change the pattern with which your heart beats.Īrrhythmias can cause no symptoms, or you may feel discomfort, fluttering, pain, or pounding in your chest. Within the heart is a complex system of valves, nodes, and chambers that control how and when the blood is pumped. An abnormal heart rhythm is when your heart beats too fast, too slow, or irregularly.
