title: Loss of biventricular pacing due to T-wave oversensing.
abstract: The benefits obtained with cardiac resynchronization therapy are directly related to the occurrence of continuous biventricular pacing. We report a case of intermittent loss of biventricular pacing due to ventricular oversensing that worsened the functional status of the patient.
