Saul E Greenhut: Apparatus and method for diagnosis of cardiac disease using a respiration monitor. Pacesetter, Gottlieb Rackman & Reisman P C, September 24, 2002: US06454719 (121 worldwide citation)

The cardiac condition of a patient is determined by a cardiac monitor apparatus using a respiration parameter such as a current respiration signal or a respiration rate. The variability of the respiration parameter is used to generate a signal indicative of the current heart failure status of the pa ...
