탄광부 진폐증자의 일초폐활량($FEV_{1.0}$)과 폐성심의 심전도 소견

Forced Expiratory Volume in One Second and ECG Sign of Cor Pulmonale in Coal Workers' Pneumoconiosis

The medical record of ECC and pulmonary function test of 297 cases who were dead at hospital or admitted as coal workers' pneumoconiosis were used for the study of the relationship between forced expiratory volume in one second($FEV_{1.0}$) and ECG sign of pulmonale. The incidence of T wave inversion in $V_1$ lead was significantly increased as $FEV_{1.0}$ decrease. The incidence of T wave inversion in $V_1$ lead was over the half in the group of $FEV_{1.0}$ less than 0.7l.
