Key result
Intravenous nitroglycerin and streptokinase infusion resulted in dramatic clinical improvement and ST-segment resolution in a 70-year-old man with acute myocardial infarction.
Why the study?
To describe a case of acute myocardial infarction presenting with right bundle branch block.
Case Report (n=1)
This case report highlights that acute myocardial infarction can present with right bundle branch block and changeable trifascicular block, which resolved with streptokinase therapy.
Rationale: Acute myocardial infarction in the presence of right bundle branch block.Patient concerns: A 70-year-old, male heavy smoker presented with angina and hypertension.Interventions: Electrocardiography, intravenous nitroglycerin infusion, intravenous streptokinase infusion.Diagnosis: Acute myocardial infarction in the presence of with changeable trifascicular heart block.Outcomes: Dramatic clinical improvement with electrocardiographic ST-segment (whether elevation or reciprocal ST-depression) resolution.Lessons: Acute myocardial infarction may be associated right bundle branch block. Accompanied trifascicular heart block had pre-streptokinase left anterior fascicular block with left axis deviation and post-streptokinase left posterior fascicular block with right axis deviation.

YasserMohammed Hassanain Elsayed (2019) conducted a case report in Acute myocardial infarction with right bundle branch block and changeable trifascicular block (n=1). Intravenous nitroglycerin and streptokinase infusion was evaluated on Clinical improvement and electrocardiographic ST-segment resolution. Intravenous nitroglycerin and streptokinase infusion resulted in dramatic clinical improvement and ST-segment resolution in a 70-year-old man with acute myocardial infarction.
