简要总结
This investigation is designed to demonstrate the clinical safety of the EVIA/ ENTOVIS pacemaker system when used under specific MRI conditions.
详细描述
In the past, MR scans were always contraindicated for pacemaker patients. If particular prerequisites and conditions are fulfilled, MR scans can now be conducted on patients with BIOTRONIK's EVIA/ENTOVIS pacemakers in combination with the Safio S pacemaker leads, scheduled to be part of this clinical study.
The specific MRI conditions for this investigation with the EVIA/ENTOVIS pacemaker family and Safio S pacemaker leads are defined in the study protocol

结局指标
主要结局
Primary hypothesis 5: R-wave sensing attenuation
时间窗: 1 month
R-wave attenuation: R-wave amplitude decrease (between pre-MRI follow-up and 1-month follow-up) exceeding 50% or a R-wave amplitude at 1-month follow-up smaller or equal to 5.0 mV.
Primary hypotheses 2 and 3: pacing threshold rise (atrial and ventricular)
时间窗: 1 month
The atrial or ventricular MRI induced pacing threshold rise is not larger than or equal to 0.5 V between Pre-MRI and 1-month follow-up
Primary hypothesis 4: P-wave sensing attenuation
时间窗: 1 month
P-wave attenuation: P-wave amplitude decrease (between pre-MRI follow-up and 1-month follow-up) exceeding 50% or a P-wave amplitude at 1-month follow-up smaller or equal to 1.5 mV
Primary hypothesis 1: MRI and pacing system related Serious Adverse Device Effect (SADE) free rate
时间窗: 3 months
MRI and pacing system related Serious Adverse Device Effect (SADE) Free-Rate is greater than 90%.
