title: Changes in the ballistocardiogram in pulmonary hypertension.
abstract: A comparison of Bcg changes was made between a group of healthy individuals, a group of pneumopaths with normal blood pressure in the pulmonary artery at rest and another group of pneumopaths with pulmonary hypertension at rest. The tension in the pulmonary artery was measured by venous catheterization. It was found that: (1) the H wave of the Bcg was significantly higher in both groups of pneumopaths than in the group of healthy individuals, and (2) the L wave was significantly higher in pneumopathics with pulmonary hypertension at rest than in pneumopaths with pulmonary normotension and healthy individuals.
