Electrocardiographic detection of emphysema

Abstract

Emphysema of any pathogenesis (nearly always chronic obstructive pulmonary disease) verticalizes the frontal P-wave axis >60° in adults, which, as a single criterion, has screened for obstructive pulmonary disease. In patients with emphysema, the QRS was of a significantly shorter duration than that in matched control patients. We investigated whether combining these 2 criteria would better detect or screen for emphysema. From consecutive unselected daily electrocardiograms with sinus rhythm, 50 were selected with a P-wave axis of >60°. An equal control group from the same electrocardiogram continuum with a P-wave axis of ≤60° was matched for age and gender. The QRS durations were those measured by the electrocardiographic computer and manually verified individually. The charts were then reviewed for the diagnosis of chronic obstructive pulmonary disease and/or pulmonary emphysema according to the pulmonary function test and chest radiographic findings, respectively. The patients and controls were well matched demographically. Those with a vertical P axis had a strikingly greater incidence of emphysema than did the controls (86% vs 4%, respectively). The sensitivity of a P axis >60° was 96% and the specificity was 87%. The mean...Continue Reading

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
