Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is the correct definition of Ischemia?
A
lack of adequate blood supply to the heart muscle
B
a rapid uncoordinated quivering of the ventricles
C
rapid heart rate over 100 beats per minute (bpm)
D
heart rate that is substantially slower than normal, less than 60 beats per minute (bpm)
Explanation: 

Detailed explanation-1: -Myocardial ischemia (or cardiac ischemia) means your heart muscle is not getting enough blood (which contains oxygen and nutrients) to work as it should. If this lack of blood from your coronary arteries is severe or goes on for more than a few minutes, it can damage your heart muscle.

Detailed explanation-2: -Ischemic means that an organ (e.g., the heart) is not getting enough blood and oxygen. Ischemic heart disease, also called coronary heart disease (CHD) or coronary artery disease, is the term given to heart problems caused by narrowed heart (coronary) arteries that supply blood to the heart muscle.

Detailed explanation-3: -Ischemia is an absolute or relative shortage of the blood supply to an organ, i.e. a shortage of oxygen, glucose and other blood-borne fuels. A relative shortage means the the blood being supplied is inadequate to maintain tissue metabolism. Ischemia results in tissue damage because of a lack of oxygen and nutrients.
