MEDICAL PHYSIOLOGY

Detailed explanation-1: -Myocardial infarction (MI): It occurs when an area of the heart muscle (myocardium) is damaged or dies after blood supply is blocked. It’s the classic medical term for a heart attack.

Detailed explanation-2: -People often use these terms interchangeably, but they’re not the same. A heart attack is when blood flow to the heart is blocked. Sudden cardiac arrest is when the heart malfunctions and suddenly stops beating.

Detailed explanation-3: -Damage Begins to Accumulate Your vital organs-meaning your brain, lungs, kidneys, and liver-depend on a steady diet of blood, oxygen, and nutrients, which the heart pumps to them. If your organs go without these essential supplies for too long, they too will become permanently damaged and begin to shut down.

Detailed explanation-4: -The most common cause of sudden cardiac arrest is an irregular heart rhythm called ventricular fibrillation. Rapid, erratic heart signals cause the lower heart chambers to quiver uselessly instead of pumping blood. Certain heart conditions can make you more likely to have this type of heartbeat problem.
