| Popis: |
It is fair to conclude that people with a disorder in the brain and/or cardiovascular system are more likely to experience physical condition changes while driving, which may cause health-induced traffic accidents as a result. In response, we developed a sound sensing system that uses stochastic resonance to continuously capture the trunk acoustic pulse wave (or APW) transmitted through the body. We extracted a pressure waveform derived from the apical beat and the ejection wave to the chest and a pressure waveform generated by the abdominal aorta from the APW. We compared the information obtained from electrocardiogram and blood pressure readings and duly examined the possibility of predicting fluctuations in physical condition via the APW. The pressure waveform extracted from the APW was similar to the data created by heart rate and blood pressure fluctuations and showed a tendency to be disturbed when an arrhythmia occurred. Therefore, the APW could show changes in cardiovascular dynamics and fluctuations in systolic blood pressure and highlight an arrhythmia. |
