Ventricular tachycardia is a type of heart rhythm problem (arrhythmia) that starts in the heart’s bottom chamber. It typically occurs in people who have had a heart attack or other damage to their heart muscle.
VT speeds up the heartbeat in the lower chamber of the heart. This faster heartbeat affects the heart’s rhythm and its ability to pump blood to the rest of the body.
VT can be mild, with faster heart rhythms lasting only a few seconds. Others experience longer periods of VT, which can cause dangerously low blood pressure.
Over time, VT can lead to serious conditions like heart failure and cardiac arrest.
