D) An inverted T wave

Question

Quizplus · Accepted Answer

Ventricular dysrhythmias result from an ectopic focus in any portion of the ventricular myocardium.The usual conduction pathway through the ventricles is not used,and the wave of depolarization must spread from cell to cell.As a result,the QRS complex is prolonged and is always greater than 0.12 second.It is the width of the QRS,not the height that is important in the diagnosis of ventricular ectopy.
