Pneumothorax electrocardiogram
Introduction
Overview
Overview
Left-sided pneumothorax ECG will show rightward shift of the frontal QRS axis, decreased precordial R voltage, decrease in QRS amplitude, and precordial T-wave inversion. Right sided pneumothorax ECG may show decreased precordial QRS voltage, right axis deviation, and prominent R wave in V2 with loss of S wave voltage.
