Detailed explanation-1: -In tachycardia, an irregular electrical signal (impulse) starting in the upper or lower chambers of the heart causes the heart to beat faster. Tachycardia (tak-ih-KAHR-dee-uh) is the medical term for a heart rate over 100 beats a minute. Many types of irregular heart rhythms (arrhythmias) can cause tachycardia.
Detailed explanation-2: -The word tachycardia came to English from New Latin as a neoclassical compound built from the combining forms tachy-+-cardia, which are from the Greek tachys, “quick, rapid” and , kardia, “heart".
Detailed explanation-3: -What Causes It? Any number of things. Strenuous exercise, a fever, fear, stress, anxiety, certain medications, and street drugs can lead to sinus tachycardia. It can also be triggered by anemia, an overactive thyroid, or damage from a heart attack or heart failure.
