Question

During the injection of which coronary artery are ventricular arrhythmias most common?

1) Left main coronary artery
2) Left anterior descending artery
3) Left circumflex artery
4) Right coronary artery

Answer 1

Ventricular arrhythmias are most commonly seen during the injection of blood into the left anterior descending artery (LAD) of the left coronary artery.

Step-by-step explanation:

The ventricular arrhythmias are most commonly seen during the injection of blood into the left anterior descending artery (LAD) of the left coronary artery. The LAD is the second major branch arising from the left coronary artery and supplies blood to the anterior interventricular septum and portions of both ventricles. It is an important artery for the blood supply to the heart and any irregularities during its injection can lead to ventricular arrhythmias.
