A ____ pacemaker is effective when the heart is in asystole but can be dangerous if the patient still has a native underlying rhythm.

Question

Quizplus · Accepted Answer

A fixed mode pacemaker continuously paces the heart at the same rate, regardless of the underlying electrical activity of the heart. This can be effective in treating asystole, but if the patient still has a native underlying rhythm, the pacemaker may compete with the heart's own electrical signals, leading to irregular rhythms and potential harm to the patient. A random mode pacemaker randomly paces the heart, making it less effective than a fixed mode pacemaker. Standard and type I pacemakers are not specific types of pacemakers, so they do not apply in this scenario.
