Question

what type of arrhythmia is most life threatening? multiple choice atrial flutter atrial fibrillation ventricular flutter ventricular fibrillation

Explanation:

Ventricular fibrillation is a chaotic, ineffective quivering of the ventricles, preventing the heart from pumping blood effectively and quickly leading to cardiac - arrest and death if not treated immediately. Atrial arrhythmias like atrial flutter and fibrillation are generally less life - threatening as the atria contribute less to cardiac output compared to the ventricles. Ventricular flutter can also be serious but ventricular fibrillation is more life - threatening due to its immediate impact on circulation.

Answer:

D. Ventricular fibrillation
