Respiratory stress response: a novel diagnostic method for detection of significant coronary artery disease from finger pulse wave analysis during brief respiratory exercise.
Respiratory maneuvers can uncover manifestations of myocardial ischemia. Some pulse wave characteristics are associated with significant coronary artery disease (S-CAD). An innovative test using the respiratory stress response (RSR) has been developed for the detection of S-CAD based on spectral analysis of finger pulse wave oscillations measured using photoplethysmography (PPG) during deep, paced breathing at a rate of 6 breaths per minute (0.1 Hz) for 70 seconds. We evaluated this test (RSR) as an indicator of S-CAD.
