T-wave oversensing during left ventricular pacing causing inappropriate defibrillation
Introduction Cardiac resynchronization therapy (CRT) with left ventricular (LV)-only pacing has emerged as an alternative to biventricular (Bi-V) pacing used to synchronize ventricular contraction by timing LV pacing with intrinsic right ventricular (RV) conduction. Additionally, RV pacing is minimized, improving device longevity. Despite its benefits, LV pacing may not the best modality for al...
متن کاملA Fortuitous Syncope. The pitfalls of Integrated Bipolar Defibrillator Leads
Myopotential oversensing in implantable defibrillators causing inhibition of pacing and inappropriate therapies is well described. Current literature is dominated by reports of diaphragmatic muscle as the source of such far-field oversensing. Those reporting pectoral muscle sources were invariably due to unipolar sensing circuits, incorrect DF-1 connections or inappropriate programming. We repo...
متن کاملInappropriate Shock Delivered By Implantable Cardioverter Defibrillator - Cardiac Resynchronization Therapy (ICD-CRT) Due To Myopotential Oversensing
The clinical efficacy of ICD-CRT therapy depends on accurate sensing of intracardiac signals and sensing algorithms. We report the occurrence of sensing abnormality in a patient with ICD-CRT. In this patient, oversensing of myopotentials during strenuous muscular activity resulted in an inappropriate ICD-CRT discharge. Although modern ICDs are highly effective in detecting and terminating malig...
متن کاملInappropriate inhibition of biventricular pacing due to diaphragmatic myopotentials amplified by the selectable sensing filter.
A 66-year-old man with a cardiac resynchronization therapy defibrillator (CRT-D: Quadra Assura 3367-40QC, St. Jude Medical Inc.) experienced asymptomatic intermittent inhibition of biventricular pacing, mainly after meals. All measured parameters of the true bipolar ventricular lead (Durata 7122Q, St. Jude Medical Inc.) were in the normal range and general provocative maneuvers could not reprod...
متن کاملIntraoperative analysis of cross-talk inhibition between diaphragmatic and cardiac pacemakers.
To cite: Fernandes K, McLeod RL, Nikfarjam M, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015213992 DESCRIPTION Diaphragmatic pacing is advocated in select patients with ventilatory failure due to weakness or paralysis of the diaphragm to eliminate or reduce the need for ventilatory support and to enhance quality of life. In our case, a 65-year-old ven...
