Default Yes, the answer is ventricular fibrillation

The patient suffered from arteriolar plaque rupture, thrombus from which occluded the left anterior descending artery, which supplies anterior 2/3 intraventricular septum and the left ventricle myocardial muscles. Due to this condition, left ventricular muscles are short of blood and oxygen supply, which in turn interferes with ventricular function, leading to ventricular fibrillation. Ventricular fibrillation causes sudden death in patients with cardiovascular problems.

Atrial fibrillation can lead to rapid ventricular rate, in which state ventricular muscle still can contract simultaneously and pump out blood uniformly. But in the case of ventricular fibrillation, myocardial muscle of the ventrocule losses the ability to contract together, so they won't generate efficient force to pump out blood. In addition, left atrium is supplied by left circumflex coronary artery. In this question, it is anterior descending artery get occluded which transferring blood to left ventricle. So we think of problem regarding to ventricle instead of atrium.
