title: RSR' pattern and the risk of mortality in men and women free of cardiovascular disease.
abstract: This study included 6,398 participants (mean age 55 ± 0.34 years; 54% female; 49% white; 22% black; 24% Mexican; 4.3% other) free of clinical cardiovascular disease (CVD) and major ECG abnormalities. Cox regression was used to examine the association between the RSR' (incomplete right bundle branch block (RBBB) or right ventricular conduction delay) pattern and CVD and all-cause mortalities. The RSR' pattern was not associated with an increased risk of CVD (HR=1.10; 95%CI=0.63, 1.91) mortality or all-cause (HR=0.95; 95%CI=0.66, 1.35) mortality. The results were similar when the RSR' pattern was further separated into incomplete RBBB and right ventricular conduction delay. In conclusion, the RSR' pattern is a benign finding in older adults free of clinical CVD.
