Patient Problems Low Blood Pressure/ Hypotension (1914); Tachycardia (2095)

Event Date 03/21/2023

Event Type  malfunction  

Event Description

It was reported that the patient had hypotension and was in ventricular tachycardia (vt).It was found that the right ventricular (rv) lead had t-wave oversensing (twos), an increase in pacing impedance, high thresholds, and consistent rv capture was unable to be confirmed, this is thought to be caused by fusion beats or rv undersensing.It was additionally noted that there was right atrial (ra) lead undersensing that did not appear to affect mode switch or detection.The leads remain in use.No further patient complications have been reported as a result of this event.
