Patients were categorized into 4 groups: ARBBB (n=348), typical right BBB (n=374), left BBB (n=366), and non\u2010BBB (n=12\u2009798). The primary end points were in\u2010hospital SCD and CR, the secondary end points were 2\u2010year major adverse cardiovascular and cerebrovascular events. During the in\u2010hospital observation period, 334 patients (2.4%) experienced SCD, with 98 (0.7%) attributed to CR. The incidences of in\u2010hospital SCD and CR in the group with ARBBB were significantly higher than those in the other 3 groups (ARBBB versus left BBB versus typical right BBB versus non\u2010BBB: SCD, 10.6% versus 5.7% versus 4.3% versus 2.0%,\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      =0.001; CR, 5.7% versus 2.7% versus 1.3% versus 0.5%,\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      &lt;0.001).
