Summary
This study presents a case of left bundle branch block causing exercise-induced pain despite normal coronary arteries. An ischemic theory is proposed as the primary cause for this condition.
Area of Science:
- Cardiology
- Electrophysiology
- Clinical Case Study
Background:
- Left bundle branch block (LBBB) can present with diverse symptoms, including chest pain during exertion.
- Coronary artery disease is a common cause of exertional chest pain, but LBBB can occur independently.
- Understanding the pathophysiology of LBBB in the absence of obstructive coronary artery disease is crucial for accurate diagnosis and management.
