With tachycardia, the heart beats too quickly, resulting in a heart rate in excess of 100 beats per minute. When the heart beats too fast, it pumps the blood around the body less efficiently and the blood flow is reduced, starving the myocardial cells of oxygen, which could potentially cause heart attack.
