Cardiovascular collapse is a very dangerous condition that can cause permanent disability or sudden death in a short time. Understanding cardiovascular collapse and the risk of sudden death will help prevent disease more effectively.

Cardiac arrest and apnea can happen suddenly and people with cardiac arrest or apnea need first aid to compress the heart, give breathers before being transferred to the hospital. But if not done properly, it will lead to broken ribs.

In a healthy heart, cardiac signaling is usually smooth, with a normal resting heart rate of 60-100 beats/min. In people with arrhythmias, the heart rate may be faster or slower than the normal heart rate. This can cause uncomfortable, life-threatening signs and symptoms.

The conduction system in your heart is the network of nodes, cells, and signals that control your heartbeat. Each time your heart beats, electrical signals travel through your heart. These signals cause different parts of the heart to relax and contract. Dilation and contraction control blood flow through your heart and body.
