The Causes, Symptoms and Types of Tachycardia

Tachycardia is a common type arrhythmia which causes the heart to beat faster while at rest. Heart rates naturally rise during exercise or in response to certain stress and trauma. However, with tachycardia, the heart beats abnormally fast while a person is at rest. There are several types of the condition and treatment options vary.

Information. Electrical signals sent across the heart control a person’s heart rate. A normal resting rate is between 60 beats and 100 beats per minute. With tachycardia, the heart beats anywhere from 100 to as much as 400 beats per minute. Reputable sources including the AHA consider a heart rate over 100 beats a minute is too fast for normal cardiac function. With tachycardia, electrical signals are sped up by an abnormality; as a result, the resting rate increases significantly. Tachycardia may not cause symptoms or lead to complications. However, if it does cause issues and is left untreated, tachycardia can lead to serious issues such as stroke, heart disease, sudden cardiac arrest or death. Treatment options are dependent on the type of tachycardia, severity and other health conditions. Your doctor will help determine the right treatment plan.
