METHOD, DEVICE AND ARRANGEMENT FOR DETERMINING PULSE TRANSIT TIME |
摘要 |
An arrangement (100) and a device (101) for determining pulse transit time comprise an accelerometer (102) and a pulse wave sensor (103) for sensing a pulse wave. The accelerometer (102) determines a cardiac systole, and the pulse wave sensor (103) determines the pulse wave induced by said cardiac systole ejection. A first trigger signal is determined at the moment of said determined cardiac systole, and a second trigger signal at the moment of said determined pulse wave. The pulse transit time is then determined as a time difference between said first and second trigger signals. |
