Summary
Non-invasive His bundle signal recording was improved using body surface potential maps. Unipolar beat-to-beat measurement is recommended for clinical His electrocardiography.
Area of Science:
- Cardiovascular Electrophysiology
- Biomedical Engineering
Context:
- Accurate non-invasive His bundle signal detection is crucial for diagnosing cardiac conduction abnormalities.
- Existing methods for His bundle potential measurement face challenges with signal clarity and clinical applicability.
Purpose:
- To refine non-invasive His bundle potential measurement techniques using body surface potential maps (BSPM).
- To evaluate different electrode configurations and signal processing methods for optimal His signal recording.
Summary:
- His bundle signals were measured in ten healthy individuals using a 64-channel ECG system, generating body surface potential maps (BSPM) during the PQ-segment.
- Atrial potentials were filtered using difference and differentiation methods. Various unipolar and bipolar electrode placements were tested for beat-to-beat His signal recording.
- A unipolar method with eight chest electrodes and a common true potential (CTP) reference was found optimal for clinical application, alongside stable PQ-times and HV intervals.
Impact:
- The study introduces an improved, clinically applicable unipolar beat-to-beat measurement method for non-invasive His electrocardiography.
- This advancement facilitates more accurate and accessible assessment of cardiac conduction, particularly for His bundle potentials.
