Ventricular Tachycardia

Ventricular tachycardia is a rapid heartbeat that originates from the lower chambers of the heart (ventricles). It occurs when electrical signals in the heart become abnormal, causing the ventricles to beat too quickly. This fast rhythm can reduce the heart's ability to pump blood effectively, leading to symptoms like dizziness, shortness of breath, or even fainting. In some cases, it may resolve on its own, but it can also be serious, potentially leading to more dangerous heart rhythms or cardiac arrest if untreated. It often requires medical evaluation and treatment to manage.
