Which of the following is NOT true about asynchronous pacemakers?

Question

Quizplus · Accepted Answer

Asynchronous pacemakers are not the same as demand pacemakers because they do not "demand" a heartbeat before firing. Instead, they fire at a set rate regardless of the heart's intrinsic activity. B is also not true because asynchronous pacemakers are not fixed-rate pacemakers, which fire at a constant rate but can be inhibited by intrinsic beats. Option C is true because, as mentioned, asynchronous pacemakers do not synchronize with the heart's intrinsic beats. Option D is true because an asynchronous pacemaker can cause fibrillation if the paced beat coincides with the vulnerable period of the intrinsic beat's cardiac cycle.
