Key result
In a patient with inferior wall myocardial infarction, right bundle branch block, and left anterior hemiblock, administration of intravenous tenecteplase led to resolution of chest discomfort and >50% resolution of ST-segment elevation.
Why the study?
Conduction disturbances like fascicular and bundle branch blocks alter QRS morphology and secondary ST-T waves, presenting challenges in diagnosing acute myocardial ischemia and STEMI.
Case Report (n=1)
Conduction disturbances such as RBBB and LAHB can alter QRS morphology and ST-T waves, complicating the ECG diagnosis of acute myocardial infarction.

Requires careful ECG interpretation in inferior MI with bifascicular block; hypothesis-generating for refined diagnostic criteria.
Bhasin et al. (2022) conducted a case report in Inferior wall myocardial infarction with conduction abnormalities (n=1). Intravenous tenecteplase followed by percutaneous coronary intervention was evaluated on Resolution of chest discomfort and ST-segment elevation. In a patient with inferior wall myocardial infarction, right bundle branch block, and left anterior hemiblock, administration of intravenous tenecteplase led to resolution of chest discomfort and >50% resolution of ST-segment elevation.
