Clinical analysis of chronic pulmonary heart disease complicated with arrhythmia

Abstract

Objective To observe the clinical features,types and pathogenesis of patients with chronic pulmonary heart disease complicated with arrhythmia. Methods One hundred and ninety-three patients with chronic pulmonary heart disease were enrolled from May 2009 to May 2013. 24 h ECG mo-nitor and repeated 12 - lead ambulatory electrocardiogram were carried out. One hundred and twenty pa-tients complicating arrhythmia were found. All patients underwent conventional treatment,and types and complications of arrhythmia were investigated. Results Among the 193 patients,120 cases were compli-cated with arrhythmia,and there were 52 cases of Sinus tachycardia, 26 cases of atrial premature contraction,11 cases of atrial tachy-cardia,10 cases of atrial fibrillation,6 cases of ventricular premature contraction,4 cases of right bundle branch block,3 cases of left bundle branch block,3 cases of atrioventricular block,5 cases of atrial flut-ter. The incidence of pulmonary infection,heart failure,hypoxemia,electrolyte imbalance and acid-base disorders were higher in arrhythmia patients than that in patients without arrhythmia（P 〈 0. 05）. Con-clusions There is high proportion of patients with chronic pulmonary heart disease complicated with ar-rhythmia,such as sinus tachycardia and atrial/ ventricular premature contraction. Lung infections,hypox-ia,heart failure and electrolyte imbalance are common inducing factors,therefore,chronic pulmonary heart disease complicated with arrhythmia may be ameliorated under appropriate treatment.
