Title:
患者の血行関連状態を測定するための圧モニタ・システム
Document Type and Number:
Japanese Patent JP3566725
Kind Code:
B2
Abstract:
A method and apparatus for monitoring and measuring the hemodynamic status of a patient's pulmonary pressure and right atrial pressure. The aforementioned is achieved by using an implanted absolute pressure sensor located in the right ventricle, coupled to an implantable monitoring device, which records pressure values in response to a combination of sensed electrical depolarizations of the atrium and ventricle and occurrence of first and second derivatives of the pressure signal having values less than zero.
