Abstract excerpt
BACKGROUND: The PR interval on the ECG reflects atrial depolarization and atrioventricular nodal delay which can be partially differentiated by P wave duration and PR segment, respectively. Genome-wide association studies have identified several genetic loci for PR interval, but it remains to be determined whether this is driven by P wave duration, PR segment, or both. METHODS AND RESULTS: We replicated 7 of the...
