Supraventricular Tachycardia, SVT

Supraventricular tachycardia, or SVT, is a condition in which the heart beats too fast, which can prevent the body from getting enough blood flow. SVT begins in the upper chambers of the heart (atria), which are located above the heart’s lower chambers (ventricles), and is caused by abnormal electrical signals in the heart. SVT does not always cause problems, but in more serious cases it can result in symptoms such as light-headedness, fainting, chest pain, shortness of breath, and fatigue. It becomes a problem when episodes are frequent, last a long time, or symptoms are present. SVT is sometimes called paroxysmal supraventricular tachycardia (PSVT) or paroxysmal atrial tachycardia (PAT); paroxysmal means “from time to time”.
