Eligibility
Inclusion criteria
* Subject is willing and capable of providing informed consent * Subject has a Class I or II indication for implantation of a single(VVI (R) only) or dual chamber pacemaker or a CRT-P system according to the ACC/AHA/HRS, or ESC guidelines * Subject is willing and capable of participating in all testing/ visits associated with this clinical study at an approved clinical study center and at the intervals defined by this protocol * Subject is age 18 or above, or of legal age to give informed consent specific to state and national law
Exclusion criteria

Primary
| Measure | Time frame | Description |
|---|---|---|
| Effectiveness 3 | Lead implant through 3 month follow up | Clinically acceptable pacing impedance between 300 Ω and 1300 Ω |
| Safety 1 - Percentage of Leads Free From Complication (0 - 3 Months) | Lead implant through 3 month follow up | Lead-related complication-free rate from lead implant through the three month follow-up, based on complications that are related to the INGEVITY Lead. The performance goal based on similar leads was set in collaboration with FDA at 91.4% |
| Safety 2 - Percentage of Leads Free From Complication (3 - 24 Months) | 3 months through 12 months post implant | Lead-related complication-free rate from three months post-implant through twelve months post implant, based on complications that are related to the INGEVITY Lead. The performance goal based on similar leads was set in collaboration with FDA at 94%. |
| Safety 3 - Hazard Rate of Lead-Related Complications | Implant through 12 months (including available data beyond 12 months) | Hazard rate of lead-related complications over time. This endpoint will use the Weibull distribution to estimate the hazard over time by evaluating the Weibull shape parameter. A Weibull shape greater than one (\>1), equal to one (=1) and less than one (\<1) indicates accelerating, constant, and decelerating hazard of lead-related complications over time, respectively. This endpoint requires the Weibull shape estimate to be less than 1. |
| Effectiveness 1 | Lead implant through 3 month follow up | The bipolar pacing threshold at 0.5 ms at three months post-implant \< 1.5 V |
| Effectiveness 2(Right Atrium) | Lead implant through 3 month follow up | P-wave sensed amplitude at three months post-implant \> 1.5 mV |
| Effectiveness 2(Right Ventricle) | Lead implant through 3 month follow up | R-wave sensed amplitude at three months post-implant \> 5 mV |
