Uncontrolled contractions of the heart ventricle that are often associated with myocardial infarction are known as:
A) ventricular tachycardia
B) ventricular fibrillation
C) ventricular shock arrhythmias
D) atrial fibrillation
E) complete heart block

Question

Quizplus · Accepted Answer

Ventricular fibrillation is a life-threatening arrhythmia in which the ventricles contract in a rapid, uncoordinated manner, leading to a complete cessation of effective blood flow. It can result from myocardial infarction and requires immediate medical intervention, including defibrillation. Ventricular tachycardia is also a serious arrhythmia, but the ventricles still contract in a somewhat coordinated manner. The other choices are not directly related to the described symptom of uncontrolled ventricular contractions.
