Event or Problem Description
It was reported that during the implant procedure of the subcutaneous right ventricular (rv) lead, there were high defibrillation threshold (dft) testing with multiple shocks and some needed external methods to convert the rhythm.The first two dft failed on the first device check and were converted externally.The mobile programmer abort command was pressed after the arrhythmia was terminated but prior to the charge delivery by the device, and it did not respond twice, resulting in the patient receiving an extra shock twice on separate dft attempts even after pressing abort multiple times.The third dft was performed after the lead was repositioned.Following the procedure, it was reported that the patient had a pneumothorax.The rv lead remains in use.No further patient complications have been reported as a result of this event.
