CLINICAL MEDICINE

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: -Tachycardia in adults refers to a heart rate of more than 100 beats per minute.

Detailed explanation-3: -An electrocardiogram is the most common tool used to diagnose tachycardia. This painless test detects and records the heart’s electrical activity using small sensors (electrodes) attached to the chest and arms. An ECG records the timing and strength of electrical signals as they travel through the heart.

Detailed explanation-4: -What is tachycardia? When you have tachycardia, your heart beats faster than normal for a few seconds to a few hours. Normally, your heart rate is 60 to 100 beats per minute when you’re not active. When your heart beats more than 100 times a minute at rest, that’s tachycardia.
