Abstract
An arrangement () and a device () for determining pulse transit time comprise an accelerometer () and a pulse wave sensor () for sensing a pulse wave. The accelerometer () determines a cardiac systole, and the pulse wave sensor () 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.
