Ventricular fibrillation definition

Ventricular fibrillation means a disturbance in the normal rhythm of the heart that is characterized by rapid, irregular, and ineffective twitching of the ventricles of the heart.

Ventricular fibrillation means a disturbance in the nor- mal rhythm of the heart that is characterized by rapid, irregular, uncoordinated and ineffective twitching of the lower chambers, or ventricles, of the heart.

Ventricular fibrillation means the most common arrhythmia that causes cardiac arrest. It is a condition in which the heart’s electrical impulses suddenly become chaotic; often without warning, causing the heart’s pumping action to stop abruptly.

Examples of Ventricular fibrillation in a sentence

  • Ventricular fibrillation and ventricular tachycardia are rare complications, but follow appropriate protocols if either occur.2. Muscle tremors may complicate evaluation of pulses; femoral pulse may be more accurate.3. Pacing may cause diaphragmatic stimulation and apparent hiccups.

  • Ventricular fibrillation: In an attempt to evoke ventricular fibrillation, trains of simulated M26 or X26 Taser waveforms (designed to mimic the discharge patterns of the respective Taser devices) were applied to the ventricular muscle.

  • Method: Excised, spontaneously beating guinea-pig hearts (the Langendorff preparation) were used to determine if the predicted M26 and X26 waveforms in human heart could induce either or both of two phenomena:• Ventricular ectopic beats (VEBs) – cardiac contractions out with the normal inherent rhythmicity of the heart; • Ventricular fibrillation (VF) – chaotic, asynchronous contractions of the heart muscle fibres that result in no effective heart output.
