Electrophysiological Evaluation Practice Test

The main concept tested is how a pacemaker or ICD is evaluated for actual performance and safety after implantation, focusing on how well the device and its leads will function in real life. The best endpoints are about electrical performance and therapy behavior: lead sensing and capture thresholds determine whether the device can reliably detect intrinsic heart activity and deliver pacing effectively; intact insulation checks ensure the leads won’t leak current or fracture, which could cause inappropriate sensing or failure to pace. The absence of unintended shocks is crucial for ICDs, confirming that the device does not misinterpret signals and deliver therapy when it isn’t needed. And appropriate therapy programming ensures the device’s detection criteria, therapy sequences, and pacing parameters are aligned with the patient’s rhythm and clinical needs, so therapies are delivered correctly and safely. Battery life estimates and cosmetic or wound-related aspects relate to other concerns, not the ongoing functional performance of the device.
