Question

Quizplus · Accepted Answer

Undersensing occurs when the pacemaker fails to detect the patient's own cardiac electrical activity and inappropriately triggers pacemaker activity. This can lead to the pacemaker never turning off and can cause serious complications such as pacemaker-mediated tachycardia. Oversensing occurs when the pacemaker detects electrical activity that is not cardiac in origin, such as muscle or diaphragmatic activity, and can lead to inappropriate inhibition of pacemaker activity. Triggering and malsensing are not commonly used terms in pacemaker technology.
