Exercise-induced changes in QT interval are smaller in COPD patients and have no impact on mortality

[摘要] ExtractChronic obstructive pulmonary disease (COPD) is a systemic disorder with significant pulmonary and extrapulmonary manifestations [1]. The right and left heart and the great vessels may be affected [2]. Specifically; patients with COPD (especially those with hypoxaemia) have functional alterations in cardiac autonomic modulation; manifested by tachycardia at rest; reduced baroreflex sensitivity; reduced heart rate variability and abnormal recovery of heart rate following exercise [3].
