Diagnostic value of electrocardiographic investigations in preoperative evaluation of patients with lung cancer.
The pulmonary hypertension and cor pulmonale in patients before lung tissue resection must be predicted even if invasive studies are required. The purpose of the study was to evaluate the diagnostic value of electrocardiographic investigation for patients with lung cancer, considered to be candidates for lung tissue resection. The study comprised 50 male patients with bronchial carcinoma before lung tissue resection. All of them had gasometric, and hemodynamic parameters of pulmonary circulation assessed at rest and after exercise. The ECG and spirographic investigations were done in all patients. It was found that 23 of 50 patients had electrocardiographic traits of right ventricle hypertrophy and only one of them had normal pulmonary circulation parameters. There were also found correlations between ECG curve and FEV1%, most of gasometric and some of pulmonary hemodynamic parameters.
