METHODS AND APPARATUS FOR MONITORING CARDIOVASCULAR REGULATION USING HEART RATE POWER SPECTRAL ANALYSIS.

摘要

A patient monitor (4 ) having an electrocardiographic signal source (2) and an electroplethysmographic respiratory signal source (3) provides inputs to an ECG trigger circuit (5) and an analog-to-digital interface respectively which in turn provide data and control signals to a personal computer (7) programmed to automatically correct the data for artifacts and analyze the spectral densities of the signals which are then shown on display (9).
