Markers of sudden cardiac death associated with the ventricular-paced 12-lead ECG.

ABSTRACT:

Introduction

ECG markers are associated with increased risk of sudden cardiac arrest (SCA) on the sinus rhythm ECG. A sizeable subgroup of patients at risk receives cardiac implantable electrical devices, but there are no known markers of SCA risk on the ventricular-paced (VP) ECG.

Methods and results

We conducted a case-control analysis within a community-based SCA study in Oregon USA (2002-2020; ∼1 million catchment population) with validation in an identically designed study in California USA (2015-2023; ∼850 000 catchment population). SCA cases included adults (≥18 years) with archived VP ECGs obtained prior and unrelated to their SCA. Controls met the same ECG criteria but without history of ventricular arrhythmias or SCA. The discovery analysis included 158 participant
