    Ventricular repolarization proceeds from the heart base to apex, independent of activation. This study clarifies repolarization sequence and electrical systole duration, impacting T wave interpretation in bundle branch block.

    Area of Science:

    • Cardiology
    • Electrophysiology
    • Cardiac Anatomy

    Context:

    • Understanding ventricular repolarization is crucial for interpreting electrocardiograms (ECGs).
    • Previous studies have not fully elucidated the precise sequence and directional properties of ventricular repolarization.
    • Investigating the relationship between activation and repolarization sequences is essential for cardiac health assessment.

    Purpose:

    • To determine the sequence and direction of ventricular repolarization.
    • To compare the duration of electrical systole between right and left ventricles.
    • To analyze the impact of bundle branch block on T wave morphology and repolarization.

    Summary:

    • This study investigated ventricular repolarization in dogs using epicardial and bipolar leads.

  • Findings indicate repolarization progresses from the base to the apex, independent of activation.
  • Electrical systole duration differs between ventricles and is affected by block, influencing T wave interpretation.

    • Impact:

    • Provides a foundational understanding of ventricular repolarization sequence and its determinants.
    • Offers insights into the electrophysiological basis of T wave abnormalities in bundle branch block.
    • Contributes to improved diagnostic interpretation of ECGs in various cardiac conditions.
