Abstract

Patients with chronic obstructive pulmonary disease (COPD) have an increased risk for cardiovascular events, and electrocardiography has an important role in detecting cardiac side effects of COPD-related hypoxia.

Keywords: Electrocardiography; Chronic obstructive pulmonary disease; QT interval; QT dispersion; Frontal plane QRS-T angle; Fragmented QRS

Core Tip: QT parameters and frontal plane QRS-T angle may provide useful information regarding subclinical left ventricular dysfunction in patients with chronic obstructive pulmonary disease. In addition to standard electrocardiography parameters, these parameters may also be useful in demonstrating cardiac side effects of chronic obstructive pulmonary disease.
