New ECG changes associated with a tension pneumothorax: a case report

Chest. 1999 Jun;115(6):1742-4. doi: 10.1378/chest.115.6.1742.


This case report reveals new ECG changes associated with a left tension pneumothorax, specifically, PR-segment elevation in the inferior leads and reciprocal PR-segment depression in the aVR lead. A mechanism of atrial injury and/or ischemia is proposed as the cause, and the ECG changes associated with a left tension pneumothorax are briefly reviewed.
