Implication

Prospective study reveals conduction system pacing preserves interventricular synchrony in advanced AV block, highlighting ultra-high-frequency ECG for noninvasive assessment.

Key Points

Conduction system pacing preserves electrical and mechanical synchrony over one year, whereas right ventricular pacing markedly worsens interventricular dyssynchrony.
Interventricular electrical delay showed 0 ± 4 ms change with conduction system pacing, contrasting with a 24 ± 5 ms increase observed following right ventricular pacing.
Prospective assessment across 53 patients confirms that ultra-high-frequency ECG reliably tracks interventricular mechanical delay and identifies pacing dyssynchrony.
