Right and left bundle branch block in acute inferior myocardial infarction
Singapore Medical Journal
|March 10, 2000
Insights
An 88-year-old man experienced acute myocardial infarction affecting multiple heart regions. This cardiac event was complicated by intermittent bundle branch blocks affecting both sides of the heart.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Myocardial infarction (MI) is a leading cause of mortality and morbidity worldwide.
- Bundle branch block (BBB) can complicate the presentation and management of acute MI.
Observation:
- An 88-year-old male patient presented with symptoms indicative of acute myocardial infarction.
- The infarction involved inferior, posterior, and right ventricular regions of the heart.
Findings:
- The patient exhibited intermittent complete right bundle branch block (RBBB) and left bundle branch block (LBBB).
- These conduction abnormalities occurred concurrently with the acute Q wave myocardial infarction.
Implications:
- This case highlights the complex interplay between acute myocardial infarction and conduction system disturbances.
- Understanding these associations is crucial for accurate diagnosis and effective patient management in elderly individuals.
Abstract:
An 88-year-old man presented with acute Q wave inferior, posterior and right ventricular myocardial infarction which was associated with intermittent complete right and left bundle branch block.
