结局指标
主要结局
Epicardial potentials
时间窗: Day one, direct measurement
Primary outcome data include reconstructed electrical heart activity such as: - epicardial potentials (units: millivolts \[mV\]) These outcome data are obtained at the moment of inclusion. The primary outcome measures are a comparison of the primary outcome data with invasive outcome data available from clinical records: - Reconstructed epicardial potentials (mV) will be compared to selected invasive epicardial potentials (mV) obtained from catheter-based recordings or pacemaker-based recordings available as clinical data
Epicardial electrograms
时间窗: Day one, direct measurement
Primary outcome data include reconstructed electrical heart activity such as: - epicardial electrograms (units: millivolts \[mV\] over milliseconds \[ms\]) These outcome data are obtained at the moment of inclusion. The primary outcome measures are a comparison of the primary outcome data with invasive outcome data available from clinical records: - Reconstructed electrograms (mV) will be compared to selected invasive epicardial electrograms (mV) obtained from catheter-based recordings or pacemaker-based recordings available as clinical data
Epicardial activation and recovery sequences
时间窗: Day one, direct measurement
Primary outcome data include reconstructed electrical heart activity such as: - epicardial activation and recovery isochrones (units: milliseconds \[ms\]) These outcome data are obtained at the moment of inclusion. The primary outcome measures are a comparison of the primary outcome data with invasive outcome data available from clinical records: - Reconstructed activation and recovery sequences (ms) will be compared to recorded catheter-based sequences from clinical data (ms).
