Forced Expiratory Volume in One Second and ECG Sign of Cor Pulmonale in Coal Workers' Pneumoconiosis
Abstract
- The medical record of ECG and pulmonary function test of 297 cases who were dead at hospital or admitted as coal workers' pneumonociosis were used for the study of the relationship between forced expiratory volume in one second(FEV1.0) and ECG sign of pulmonale. The incidence of T wave inversion in V1 lead was significantly increased as FEV1.0 decrease. The incidence of T wave inversion in V1 lead was over the half in the group of FEV1.0 less than 0.7 liter.
