WebIn one case, inappropriate atrial antitachycardia pacing due to R wave oversensing triggered sustained ventricular tachycardia, terminated eventually with a high energy shock. In dual chamber ICDs, FFRWOS may represent a frequent phenomenon possibly leading to serious consequences. WebJul 1, 2004 · Far-field R-wave sensing (FFS) has been identified as the most common cause of inappropriate mode switch in dual chamber pacemakers [7, 8]. False positive mode switches can result in a loss...

WebFar-Field R-Wave Oversensing. Far-field R-wave (FFRW) oversensing by the atrial lead is a relatively frequent issue, and may occur with ventricular sensing or with ventricular pacing ( Fig. 37-22 ).
