Transient complete right bundle branch block due to lung contusion: case report

Abstract

Introduction: Right bundle branch block (RBBB) may occur in lung diseases and cardiovascular diseases. Case Report: A 25-year-old male patient was admitted to emergency department after a motorcycle accident. Contusion was detected in bilateral lungs, and pneumothorax with laceration were detected in the right lung. ECG revealed 103 bpm, right axis deviation, and complete RBBB. ECG revealed 83 bpm, complete RBBB continued at the 6th hour after tube thoracostomy, and high sensitive TnI was normal. Chest X-ray was normal on the 4th day of hospitalization, and ECG revealed 74 bpm, normal sinus rhythm. Conclusion: In thoracic trauma, ECG changes may develop as a result of lung contusion. ECG findings improve as the lung contusion heals.
