Trial Outcomes & Findings for BIO|CONCEPT.ECG-Library (Collection of ECG Signals for Development of Algorithms) (NCT NCT04243070)

NCT ID: NCT04243070

Last Updated: 2025-03-11

Results Overview

All ECG recordings were evaluated by an internal board and all patients were allocated to one of 15 groups (covering 14 ECG patterns of interest and one group for "no ECG pattern of interest recorded").

3-channel Holter ECG Recording for EPS Patient
Patients participating in an EPS will undergo a 3-channel Holter ECG recording in parallel to the standard 12-channel Holter ECG recording during the EPS followed by an optional 24 h observation period 3-channel Holter ECG recording: 3-channel Holter ECG recording for patients undergoing an EPS
12-channel Holter ECG Recording for Non-EPS Patients
Patients scheduled for a follow-up for their heart disease will undergo a 12-channel Holter ECG recording while participating in a Body Motion test followed by a 24 h observation period 12-channel Holter ECG recording: 12-channel Holter ECG recording for patients undergoing a routine follow-up

PRIMARY outcome

Timeframe: 24 hours

Population: According to the statistical analysis plan it was pre-specified to report the number of successful Holter recordings per ECG pattern for all patients irrespective of the method for Holter recording.

All ECG recordings were evaluated by an internal board and all patients were allocated to one of 15 groups (covering 14 ECG patterns of interest and one group for "no ECG pattern of interest recorded").
