Abstract:
An analyzing system including a detector system for measuring electrocardiograms, pulses and voice sounds at the same time, the detector system comprising:a flexible framework; a electrocardiogram detector comprising at least two electrodes, wherein these two electrodes are integrated by the flexible framework and the flexible framework can pressurize to keep the electrodes in contact with a subject for detecting electrocardiograms from the subject's neck; and a pulse detector comprising at least a microphone, wherein the microphone is disposed on the subjects' neck adjacent to the subject's carotid arteries and collects pulse sounds and vibrations from the carotid arteries and voice sounds from the subject's vocal chord, and wherein the microphone is integrated with the electrodes by the flexible framework and the flexible framework can pressurize to keep the microphone in contact with the subject, wherein the electrocardiogram detector and the pulse detector further comprise at least an amplifier, a filter and a analog-to-digital converter, so that the collected pulse sounds, vibrations and voice sounds are transformed into electrical signals and the electrocardiograms and transformed electrical signals are process and outputted as digital signals; and the analyzing system further comprising a computing system for analyzing the digital signals from the electrocardiograms, pulse sounds, vibrations and voice sounds, wherein the computing system detect and mark heart beats from the digital signals from the electrocardiograms, pulse sounds and vibrations and perform digital signal processing processes to characterize heart rate variability with quantified parameters, thus obtaining an analyzing result.
