Question

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

Explanation:

Ventricular fibrillation is a chaotic, ineffective quivering of the ventricles. It prevents the heart from pumping blood effectively to the body and brain, leading to cardiac arrest and death if not treated immediately. Atrial arrhythmias like atrial fibrillation and atrial flutter are generally less immediately life - threatening as the atria contribute less to cardiac output compared to the ventricles. Ventricular flutter is also serious but ventricular fibrillation is more life - threatening due to its more disorganized and ineffective nature of heart muscle contraction.

Answer:

D. Ventricular fibrillation
