ECGs recorded at baseline, discharge, and 12 months were retrospectively analyzed. Intrinsic rhythm, PQ interval, QRS duration, and atrioventricular and intraventricular conduction were evaluated and compared between both groups.<\/jats:p>\n                  <jats:p>Patients in both groups had comparable Society of Thoracic surgeons risc (STS) scores (2.9\u2009\u00b1\u20091.6 vs. 3.1\u2009\u00b1\u20092.2, p\u2009=\u20090.32) and comparable baseline characteristics.

At baseline, the mean QRS width was 95.7\u2009\u00b1\u200925.5\u2009ms in the RDAVR group, and 97.3\u2009\u00b1\u200923.5\u2009ms in the AVR group, respectively (p\u2009=\u20090.590). At discharge, the mean QRS width in the RDAVR group was significantly increased with 117.4\u2009\u00b1\u200928.6\u2009ms and a mean \u0394QRS width of 21.7\u2009\u00b1\u200926.3\u2009ms (p\u2009&lt;\u20090.001) compared with baseline.
