[Clinical function of the myocardium and cardio- and hemodynamics in patients with pectus carinatum deformity].

Seventy patients with pectus carinatum were examined. All the patients demonstrated the minimal signs of connective tissue deficiency. The ECG readings showed incomplete blockade of the bundle of His, ventricular extrasystole, WPW and CLC syndromes, and metabolic alterations in the myocardium. Mitral valve prolapse was discovered in 97% of cases by echocardiography. There was a decrease in myocardial contractility along with changes in cardio- and hemodynamics, which were more marked in patients having the corporocostal type of pectus carinatum. The correlation of these values with chest deformity was revealed.
