Heart Attack and Sudden Cardiac Death Symptoms

Understanding Heart Attacks

A heart attack, medically known as myocardial infarction, occurs when the coronary arteries become severely narrowed or blocked due to a buildup of plaque over time. This blockage prevents oxygen-rich blood from reaching a section of the heart muscle, leading to tissue damage or death. If not treated promptly, a heart attack can lead to severe complications such as shock or sudden cardiac arrest.

Signs of Sudden Cardiac Death

Sudden cardiac death typically presents with immediate and severe symptoms. The affected individual may suddenly lose consciousness, experience a drop in blood pressure, and show signs of absent heart rate. Breathing and heartbeat may also stop abruptly. In such cases, immediate action is crucial to increase the chances of survival.

Emergency Response and CPR

When faced with a cardiac emergency, it's vital to initiate cardiopulmonary resuscitation (CPR) as soon as possible. Proper CPR technique involves kneeling beside the patient, placing the heel of one hand on the center of the chest, and placing the other hand on top. Using your body weight, perform chest compressions at a rate of approximately 60 to 140 per minute. This helps maintain blood circulation and delivers oxygen to vital organs until professional medical help arrives.
