Study Results
Participant Flow
Recruitment Details | Per the clinical investigation protocol, IDE subjects (n=54) who did not consent to roll over into the post approval study (PAS) at sites participating in the post approval study, were included in primary endpoint analyses. Since these subjects are not enrolled into the PAS, they are not reflected in the participant flow. |

Adverse Events
Time Frame | Complications and observations post implant through 5 years | |
---|---|---|
Adverse Event Reporting Description | Complications are considered serious adverse events. A complication is an event caused by or associated with the study device, system component(s) and/or procedure that requires invasive intervention (e.g. post-implant lead dislodgement requiring repositioning). An observation is an event caused by or associated with the study device, system component(s) and/or procedure that does not require invasive intervention (e.g. over-sensing or loss of pacing capture requiring reprogramming) | |
