Quizplus · Accepted Answer

Under normal conditions,the junction never has a chance to escape and depolarize the heart because it is overridden by the sinus node.However,if the sinus node fails,the junctional impulses can depolarize completely and pace the heart.In this strip,the ventricular rate is 38.P waves are absent,and the QRS has a normal width.
