Why the study?
Does device programming using V-V pace delay eliminate T-wave oversensing in patients with biventricular ICDs?
Does device programming using V-V pace delay eliminate T-wave oversensing in patients with biventricular ICDs?
Programming a V-V pace delay for sequential biventricular pacing can effectively eliminate T-wave oversensing and prevent inappropriate ICD shocks.
May resolve T-wave oversensing in biventricular ICDs without compromising detection; hypothesis-generating and requires prospective validation before broader adoption.
T-wave oversensing represents a common cause of inappropriate shocks in patients with implanted cardiac defibrillators. This case report demonstrates a strategy of device programming using V-V pace delay (sequential rather than simultaneous biventricular pacing) to eliminate T-wave oversensing without decreasing sensitivity to detect true tachyarrhythmia.
