| ventricular septal defect |
Hole in the heart...specifically a residual communication between the two lower heart chambers. The higher blood pressure is usually on the red (or left) side of the heart, so the blood flow across the defect is towards the lower pressure (right) side. In some complex congenital defects the pressure and flow are reversed. VSDs vary in size and location. Repair depends on the anatomy and the location of the defect.

| ventricular fibrillation |
(VF): a very fast, irregular heart rate caused by abnormal impulses starting from several areas of the ventricle. The heart beats so fast that it is unable to pump any blood to the body. A heart in fibrillation may beat over 300 times a minute. A person in fibrillation passes out and needs immediate medical attention in order to live.

| ventricular tachycardia |
(VT): a fast heartbeat caused by abnormal impulses coming from a single area of the ventricle. The rapid rate of 120-250 beats per minute may produce dizziness, weakness, blind spots and, eventually, unconsciousness.

| ventricular a. |
an aneurysmal dilatation of a portion of the wall of a ventricle, usually the left, or, rarely, a saccular protrusion through it (false a. of the heart). It is usually consequent to myocardial infarction but other causes, such as bacterial endocarditis or trauma, have been described.

| ventricular assist d. |
a circulatory support device that augments function of the left ventricle, the right ventricle, or both; it consists of one or two implanted or extracorporeal pumps with afferent and efferent conduits attached so as to provide mechanically assisted pulsatile blood flow. See left ventricular assist d., right ventricular assist d., and biventricular assist d.
