Ventricular FibrillationAka: Pulseless Ventricular Tachycardia
Ventricular Fibrillation (C0042510) | |
|---|---|
| Definition (MSH) | A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST. |
| Definition (CSP) | arrhythmia characterized by fibrillary contractions of the ventricular muscle due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricle. |
| Definition (NCI) | Arrhythmia characterized by fibrillary contractions of the ventricular muscle due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricle. |
| Definition (NCI) | Arrhythmia characterized by fibrillary contractions of the ventricular muscle due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricle. |

Tachycardia, Ventricular (C0042514) | |
|---|---|
| Definition (MSH) | An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation). |
| Definition (NCI) | An abnormally rapid ventricular rhythm with aberrant ventricular excitation, usually in excess of 150 beats per minute. |
| Definition (NCI) | A tachycardia arising distal to bundle of His, with a rate greater than 100 beats per minute. |
