Description
Teodor Serban and co-authors check how the spot where doctors record a key heart signal changes its reading, in this 2026 study. The His-ventricular interval times the heart's lower wiring and flags hidden conduction disease. Sixty-seven patients having ablation for atrial fibrillation had the interval mapped with a high-density catheter at three sites. A standard catheter reading served as reference.
Site mattered a lot. The proximal spot gave the longest times and caught the most abnormal delays; the right bundle spot gave the shortest. Sex mattered too: women's intervals ran systematically shorter than men's, while wiring speed itself did not differ. Surface ECG numbers predicted the mapped values poorly. The authors urge precise recording sites and sex-aware cutoffs when judging conduction delay.
