In tachycardia, an irregular electrical signal, called an impulse, starts in the upper or lower chambers of the heart. This causes the heart to beat faster.

Tachycardia is when the heart beats too fast when at rest — at a rate of more than 100 beats per minute. This can depend on age, health status and physical condition.

Junctional tachycardia is an automatic tachycardia originating in the AV junction. It tends to be a regular, narrow complex tachycardia and may be a sign of digitalis toxicity.

Tachycardia is a common, treatable condition that causes rapid heartbeat. Learn what causes your heart to beat too fast, and how doctors diagnose and treat it.

Tachycardia is an abnormal heart rhythm with a fast heart rate of more than 100 beats per minute at rest. It can start in the upper or lower chambers of your heart and can range from mild to life-threatening.

Tachycardia, generally defined as a heart rate ≥100 bpm, can be a normal physiological response to a systemic process or a manifestation of underlying pathology. The normal heart rate varies with age. The normal sinus rate in infants is 110 to 150 bpm, which gradually slows with age.

A normal, healthy adult typically has a resting heart rate between 60 and 100 beats per minute. Tachycardia is defined as a heart rate over 100 beats per minute. Tachycardia that occurs as a response to stimuli, is called sinus tachycardia and is a normal heart response to meet the body's needs.

Tachycardia is a heart rate of more than 100 beats per minute. The heart normally beats at a rate of 60 to 100 times per minute, and the pulse (felt at the wrist, neck or elsewhere) matches the contractions of the heart's ventricles, the heart's two powerful lower chambers.

Symptoms can arise in every ventricular tachycardia, depending on the heart rate, the presence of underlying heart disease and the degree of systolic and diastolic heart failure.
