Does right ventricular apex pacing using a real time magnetic resonance guided electrophysiology system identify abnormal potentials more frequently in the gray zone compared to healthy tissue or dense infarct in chronic myocardial infarction?
In chronic myocardial infarction, the gray zone identified by LGE-CMR is a frequent site of abnormal electrophysiological potentials during right ventricular pacing.
Our data suggests that gray zone quantified by LGE-CMR exhibits abnormal potentials more frequently than in healthy tissue or dense infarct when right ventricular apex pacing is used.
