The purpose of this study is to evaluate long-term performance of the DF4 Connector System. This evaluation is based on the number of DF4 lead-related complications occurring during the study compared to the number of leads enrolled in the study. The DF4 systems will be followed for 5 years after implant. This study is required by FDA as a condition of approval of the DF4 Connector Systems. This study is conducted within Medtronic's post-market surveillance platform.
DF4 Lead Related Complication Rate [ Time Frame: Up to 5 Years ]
To demonstrate that the complication-free probability is greater than 92.5% at five years post-implant for the high voltage DF4 lead
Secondary Outcome Measures
Types of DF4 lead related events [ Time Frame: Up to 5 years ]
Number of DF4 lead related events grouped by type
Bipolar pacing impedance (ohms) [ Time Frame: 5 years ]
Summary statistics at 5 years post-implant will be reported.
High voltage impedance (ohms) [ Time Frame: 5 years ]
Summary statistics at 5 years post-implant will be reported
Pacing threshold (volts) [ Time Frame: 5 years ]
The pacing threshold is the minimum electrical stimulus needed to consistently depolarize the heart outside of the heart's refractory period. Summary statistics at 5 years post-implant will be reported.
Sensing amplitude (millivolts) [ Time Frame: 5 years ]
The amplitude of the intrinsic cardiac electrical signals detected by electrodes on the defibrillator lead will be summarized at 5 years post-implant.
