WebOn the other hand, the oversensing of a cardiac (T wave, P wave) or extracardiac (myopotential, interference, etc) signal can be extremely problematic in pacemaker … WebJun 5, 2010 · T wave oversensing may lead to loss of biventricular pacing [14,15]. This can be an important reason for lack of improvement or worsening functional status with biventricular pacing. Transient loss of biventricular pacing due to oversensing of tall T waves due to hyperkalemia in a patient undergoing dialysis has also been noted.
WebThe oversensing of T-waves in addition to ventricular events may push the ventricular rate into the VT/VF zone, leading to incorrect detection of VT or VF, and delivery of … WebJan 23, 2014 · Hyperkalaemia-induced T-wave oversensing during biventricular pacing will reduce the ‘dose’ of cardiac resynchronization therapy (CRT). 52 In the acute setting, when a decrease in sensitivity to an ICD system may be undesirable, T-wave oversensing may be abolished by programming to monochamber LV pacing or changing the V–V interval. 53, 54
WebOversensing may also occur when electrical events in one chamber is sensed by the lead in the other chamber, resulting in inappropriate inhibition of the pacemaker in the latter … WebT-wave oversensing is a lesser problem after paced than sensed beats because ICD blanking periods are longer after pacing and because postpacing T-wave oversensing …
