Key result
Apparent ST elevation in RBBB mimics ACS and may predict sudden cardiac death.
Why the study?
Differential diagnosis of apparent ST segment elevation in right bundle branch block is critical, as right bundle branch block is often complicated with ACS and can predict sudden cardiac death.
Case Report (n=1)
Apparent ST elevation in right bundle branch block can mimic acute coronary syndrome and requires careful differential diagnosis and monitoring.
We report a case of right bundle branch block, in which the patient's symptoms and the electrocardiogram findings mimicked those of acute coronary syndrome. In this case report, we stress the significance of apparent ST segment elevation in right bundle branch block. The differential diagnosis is important because right bundle branch block is often complicated with acute coronary syndrome. In addition, right bundle branch block with an ST segment elevation in the specific leads can be a predictor of sudden cardiac death. In such cases, close monitoring of the electrocardiogram findings and careful observation of the patient's symptoms would be necessary.

Kazama et al. (2019) conducted a case report in Right bundle branch block mimicking acute coronary syndrome (n=1). Apparent ST segment elevation in right bundle branch block can mimic acute coronary syndrome and may serve as a predictor of sudden cardiac death, requiring close electrocardiogram monitoring.
