What is the difference between ventricular tachycardia and ventricular fibrillation quizlet

The difference between the two is that in ventricular tachycardia, the lower chambers of the heart are beating much faster than they should but the overall process is happening in the right order. In ventricular fibrillation, the heart's beating process isn't happening in the right order.

External electrical defibrillation remains the most successful treatment for ventricular fibrillation (VF). A shock is delivered to the heart to uniformly and simultaneously depolarize a critical mass of the excitable myocardium.

Ventricular fibrillation is a type of irregular heart rhythm (arrhythmia). During ventricular fibrillation, the lower heart chambers contract in a very rapid and uncoordinated manner. As a result, the heart doesn't pump blood to the rest of the body.

NSVT occurs when three or more consecutive PVCs occur at a rate greater than 100 beats-per-minute (Figure 1). They may be monomorphic or polymorphic and are often present in patients presenting with nonspecific cardiac symptoms.
