We presented a unique phenomenon of 2:1 cardiac resynchronization therapy pacing due to T wave oversensing. Ultimately, by utilizing a unique feature of integrated bipolar sensing, we succeeded to eliminate the T wave oversensing signals, and restore 1:1 CRTD pacing. Importantly, this feature enabled us to overcome the T wave oversensing issue, without the need to decrease the ventricular sensitivity, which could potentially interfere with ventricular arrhythmia detection and appropriate shock delivery when required.
