Continuous variables are presented as mean±SD, and categorical data are presented as number (percentage). Differences between the 2 groups were examined using the Student t test and chi‐square or Fisher exact probability tests according to the characteristics of the data distribution. ACEI/ARB indicates angiotensin‐converting enzyme inhibitor/angiotensin receptor blocker; DDD, dual‐chamber pacemaker; RVAP, right ventricular apical pacing; RVOT, right ventricular outflow tract; VVI, ventricular demand pacing.
