“…Some rare findings described in case reports include electrical alternans ( 12 ) and ST-segment elevation in lead aVR, with ST-segment depression in leads I and V4-V6 ( 13 ). Specifically, the RBBB has been identified as an indicator of RV strain found in more severe cases of PE, with reported incidences ranging from 6% to 67% ( 8 ). However, the prognostic significance of an ECG result indicating RV strain remains inconclusive ( 14 , 15 ).…”

“…However, the incidence of complete atrioventricular block (CAVB) remains rare and noteworthy in patients with PE. Only a limited number of cases have been reported in the literature ( 3 8 ). Herein, we present the case of a 91-year-old woman who presented with CAVB and review the relevant literature.…”

“…Our case describes a patient with no known history of arrhythmias or heart disease presenting with a PE that led to acute changes in her cardiopulmonary physiology resulting in hemodynamic collapse. In PE, the pulmonary artery obstruction leads to a rise in the right ventricular pressures and a volume overload state [ 4 ]. With this volume expansion, the right ventricle may compress the interventricular septum leading to a new RBBB on the EKG.…”

“…If the patient is still in complete heart block post-treatment of PE, a long-term pacemaker device can be placed. If the heart block is resolved, then an EP study can be done to evaluate whether or not the patient requires or will benefit from a long-term pacemaker [ 4 ].…”
