Arrhythmia refers to an irregular heartbeat or abnormal heart rhythm. This condition occurs when the electrical impulses that coordinate your heartbeats don't work properly, causing your heart to beat too fast, too slow, or irregularly. While not all arrhythmias are harmful, some can be life-threatening and require immediate medical attention.

Arrhythmias can affect any age group and can be either temporary or persistent. They can vary in severity from harmless to severe, impacting your heart’s ability to pump blood efficiently, which can lead to various health complications.
