Cardiac Arrhythmia: A Disruption in Heart Rhythm

Understanding Arrhythmias

A cardiac arrhythmia, also known as an irregular heartbeat, occurs when the electrical impulses that coordinate the heart's contractions are disrupted. This can lead to the heart beating too fast, too slow, or irregularly.

Common Types of Arrhythmias

There are various types of arrhythmias, each with its unique characteristics:

• Tachycardia: Heart rate exceeds 100 beats per minute.
• Bradycardia: Heart rate falls below 60 beats per minute.
• Atrial Fibrillation: The most common arrhythmia, characterized by rapid and irregular contractions of the heart's atria.
