Is heart arrhythmia a heart disease?

Is Heart Arrhythmia The Same As A Heart Attack?

• There not the same. A heart attack (also known as a myocardial infarction) is the death of heart muscle from the sudden blockage of a coronary artery by a blood clot. Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. Blockage of a coronary artery deprives the heart muscle of blood and oxygen, causing injury to the heart muscle. Injury to the heart muscle causes chest pain and pressure. If blood flow is not restored within 20 to 40 minutes, irreversible death of the heart muscle will begin to occur. Muscle continues to die for 6-8 hours at which time the heart attack usually is "complete." The dead heart muscle is replaced by scar tissue. The heart continues to function as the tissue dies. the heart can become arrhythmic if enough of the tissue dies, this can happen in a few minutes or a few days.

• A Heart arrhythmia is when the heart has already stop beating and had no pumping function.

• An dysrhythmia (incorrectly called an arrhythmia "a-" referring to no or not) is an irregular heartbeat. Heart rates can also be irregular. A normal heart rate is 50 to 100 beats per minute. Arrhythmia's and abnormal heart rates don't necessarily occur together. Arrhythmia can occur with a normal heart rate, or with heart rates that are slow (called bradycardia -- less than 60 beats per minute). dysrhythmia can also occur with rapid heart rates (called tachycardia -- faster than 100 beats per minute). In the United States more than 850,000 people are hospitalized for an dysrhythmia each year.
