A Study on the Relation between Ballistocardiogram and Pulmonary Artererial Mean Pressure in Pulmonary Tuberculosis and Silicotuberculosis

概要

Ballistocardiography and right cardiac catheterisation were performed in succession in pulmonary tuberculosis as well as silicotuberculosis An amplitude of NO or LM segment was definitely larger in the group of pulmonary hypertension than in the group of normal pulmonary arterial pressure. There was a close positive correlation between pulmonary arterial mean pressure and the amplitude of NO or LM. Such NO (LM) showed a sharp descent with deep amplitude beneath the base line and this characteristic pattern was more significantly observed in Valsalva ballistocardiogram than in rest-breathing ballistocardiogram, "Pulmonary NO (LM)" was presented as a new concept to the diagnosis of pulmonary hypertension.
