| ventricular aberration | Abnormal intraventricular conduction of a supraventricular beat, especially where surrounding beats are normally conducted. Synonym: ventricular aberration. (05 Mar 2000) |

| ventricular afterload | Formerly, the arterial pressure or some other measure of the force that a ventricle must overcome while it contracts during ejection, contributed to by aortic or pulmonic artery impedance, peripheral vascular resistance, and mass and viscosity of blood; now, more rigorously expressed in terms of the wall stress, i.e., the tension per unit cross-sectional area in the ventricular muscle fibres (calculated by an expansion of Laplace's law utilizing pressure, internal radius, and wall thickness) that is required to produce the intracavitary pressure required during ejection. (05 Mar 2000) |
| ventricular aneurysm | Aneurysm of the ventricular portion of the membranous septum, an aneurysm that bulges toward the right in systole, often consisting of the anterior leaflet of the tricuspid valve. Synonym: cardiac aneurysm. (05 Mar 2000) |
| ventricular arrhythmia | <cardiology> A cardiac arrhythmia which originates from within the ventricles. Isolated ventricular contractions are referred to as premature ventricular contractions. Frequent premature ventricular contractions can be potentially unstable and can degrade to a more serious rhythm or cardiac arrest. (12 Jan 1998) |
| ventricular arrhythmias | Abnormal rapid heart rhythms (arrhythmias) that originate in the lower chambers of the heart (the ventricles). Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation. Both are life threatening arrhythmias most commonly associated with heart attacks or scarring of the heart muscle from previous heart attack. (12 Dec 1998) |
| ventricular arteries | Branches of the right and left coronary arteries distributed to the muscle of the ventricles. Synonym: arteriae ventriculares. (05 Mar 2000) |
| ventricular assist device | A device that supports or replaces the function of a ventricle (LVAD or RVAD indicates which ventricle). The patient's heart remains in place when this device or system is used. The device is used in patients with potentially salvageable myocardium, where centrifugal or pneumatic devices can be placed in either heterotopic or orthotopic positions (the latter is termed a total artificial heart). The function of either the left, right, or both ventricles can thus be supported for days to weeks. Either recovery of heart function or need for transplantation then becomes apparent.

| ventricular band of larynx | One of the pair of folds of mucous membrane stretching across the laryngeal cavity from the angle of the thyroid cartilage to the arytenoid cartilage; they enclose a space called the rima vestibuli or false glottis. Synonym: plica vestibularis, false vocal cord, plica ventricularis, ventricular band of larynx, ventricular fold. (05 Mar 2000) |
| ventricular bigeminy | Paired ventricular beats, the common form consisting of ventricular extrasystoles coupled to sinus beats. (05 Mar 2000) |
| ventricular bradycardia | Slowness of ventricular rate, usually implying the presence of atrioventricular block. (05 Mar 2000) |
| ventricular capture | Capture of the ventricle(s) by an impulse arising in the atria or A-V junction. (05 Mar 2000) |
| ventricular complex | The continuous QRST waves of each beat in the electrocardiogram. (05 Mar 2000) |
| ventricular conduction | Conduction of the cardiac impulse through the ventricular myocardium, represented by the QRS complex in the electrocardiogram. H-R conduction time is from the onset of the first high frequency component of the His bundle electrogram to the onset of the QRS complex of the surface electrocardiogram (normally 43 ± 12 msec); H-V conduction time is from the onset of the first high frequency component of the His bundle electrogram to the onset of the ventricular electrogram (normally approximates the H-R interval but may be a little shorter). Synonym: ventricular conduction. (05 Mar 2000) |
| ventricular diastole | Period of relaxation and repolarization of the ventricular muscle. (05 Mar 2000) |
| ventricular diverticulum | A congenital outpouching of the right or left ventricle. (05 Mar 2000) |
| ventricular fibrillation |
fast, uncoordinated, fluttering beats of the heart's ventricles, causing heart beat and pulse beat to go out of synch. This is exremely dangerous

a condition in which the ventricles contract in rapid and unsynchronized rhythms and cannot pump blood into the body.

| ventricular fibrillation |
A condition in which the purposeful, forceful, and rhythmic contraction of the ventricle is lost. Ventricular fibrillation is one of several conditions known as "arrhythmias". With ventricular fibrillation, the heart muscle has no purposeful contractile motion, which results in a loss of the pumping action of the heart. Ventricular fibrillation is fatal if not quickly treated. Ventricular fibrillation can be treated with medications, or through an electrical shock known as a defibrillation.

| ventricular fibrillation |
A serious and dangerous variant of ventricular tachycardia, often the causative agent of death. Ventricular fibrillation can be effectively terminated by applying an electrical shock to the chest cavity over the heart region. Thus, when a television episode shows a doctor holding a set of paddles in each hand and delivering jolts of electricity into the body of an unconscious patient, you are witnessing an attempt to eliminate ventricular fibrillation. ...

(V-Fib) A lethal arrhythmia characterized by the rapid, chaotic movements of the heart muscle that causes the heart to stop functioning and leads quickly to cardiac arrest.
