Changes in electrocardiographic findings after closed thoracostomy in patients with spontaneous pneumothorax

View Article: PubMed Central - PubMed

ABSTRACT

Objective: We aimed to describe electrocardiographic (ECG) findings in spontaneous pneumothorax patients before and after closed thoracostomy.

Methods: This is a retrospective study which included patients with spontaneous pneumothorax who presented to an emergency department of a tertiary urban hospital from February 2005 to March 2015. The primary outcome was a difference in ECG findings between before and after closed thoracostomy. We specifically investigated the following ECG elements: PR, QRS, QTc, axis, ST segments, and R waves in each lead. The secondary outcomes were change in ST segment in any lead and change in axis after closed thoracostomy.

Results: There were two ECG elements which showed statistically significant difference after thoracostomy. With right pneumothorax volume of greater than 80%, QTc and the R waves in aVF and V5 significantly changed after thoracostomy. With left pneumothorax volume between 31% and 80%, the ST segment in V2 and the R wave in V1 significantly changed after thoracostomy. However, majority of ECG elements did not show statistically significant alteration after thoracostomy.

Conclusion: We found only minor changes in ECG after closed thoracostomy in spontaneous pneumothorax patients.

Mentions: Moreover, in 1 case of a 72% volume of right-sided pneumothorax, the axis was changed from a normal axis to a right axis deviation after closed thoracostomy (Fig. 1). However, in 1 case of left-sided pneumothorax with a 78% volume, the axis was not changed after closed thoracostomy. In this case, left axis deviation (-70°) was present both before and after closed thoracostomy (Fig. 2).
