Cardiac arrest: Causes and triggers you must know

             Written by: Nancy Dixit

It occurs when an electrical malfunction in the heart disrupts its rhythm, preventing it from pumping blood to the brain, lungs, and other organs, causing the  heart to stop beating suddenly.

It can be caused by an underlying heart condition (such as arrhythmia, heart failure) or triggered by certain activities. Here are a few common causes:

Abnormal heart rhythms cause the heart to shake or quiver instead of pumping blood properly, which can cause cardiac arrest.

When the heart muscle thickens (cardiomyopathy), it disrupts normal contractions, increasing the risk of cardiac arrest.

Coronary artery disease restricts blood flow to the heart, leading to heart failure or arrhythmias—both potential triggers for cardiac arrest.

A lack of oxygen, heavy blood loss, or very high levels of potassium in the blood can also cause the heart to stop beating (cardiac arrest).

It includes binge drinking, drug use like cocaine,  excessive caffeine intake (especially energy drinks or powders), and recent emotional stress or flu infections.

While rare, cardiac arrest can happen during or after intense activity—especially in those with undiagnosed heart conditions.
