Data Collection for Pacemaker Recognition Through Capacitive ECG


This study evaluates the signal quality of capacitive ECG (cECG) on pacemaker patients and whether paced rhythms of the pacemaker can be distinguished from the normal beats using cECG signals.

Detailed Description

In contrast to classical gold-standard ECG, cECG electrodes can sense the electrical activity of the heart even over the clothing of the subject, which allows several applications in out-of-hospital monitoring. The proposed scenarios for cECG revolve around the unobtrusiveness of the measurement with an inferior signal quality to gold standard ECG. The electrical spikes, that come into existence due to the paced rhythms given by a pacemaker, are only visible in ECG signals recorded by adequate medical instrumentation. Whether cECG can deliver enough signal quality to identify the electrical spikes of the paced rhythms needs to be investigated by recording simultaneous normal and capacitive ECG signals.


  • Device: Capacitive ECG
    • Patients having a pacemaker will sit down on a seat bearing capacitive ECG electrodes during their routine heart checkup at the cardiology.

Arms, Groups and Cohorts

  • Other: Patients having a pacemaker
    • Patients having a pacemaker will sit down on a seat bearing capacitive ECG electrodes during their routine heart checkup at the cardiology. Simultaneously standard routine ECG measurements will take place.

Clinical Trial Outcome Measures

Primary Measures

  • Sensitivity and Specificity of Paced Rhythm Identification
    • Time Frame: up to 10 weeks after the data collection is completed for each patient
    • Cardiologists are asked to classify the heart-beats as “paced” and “normal” in a blind test of mixed normal and capacitive ECG recordings.
