A device (10) for collecting cardiovascular data relating to an individual user (U), comprising a control unit assembly (1) with an electronic controller (6) and a pneumatic unit (5), an arm band (2) having an inflatable bladder (53) and configured to surround the left arm (BG) of the individual, wherein the pneumatic unit has a pump (7) and a pressure sensor (61), and is configured to inflate and deflate the inflatable bladder, so that the electronic controller can determine the arterial pressure of the user, the device further comprising an acoustic sensor (4) being coupled to the external wall of the arm band and having a sensitive side (41) such that in use configuration, the sensitive side is adjacent to the chest of the user, whereby at least a cardiovascular timing characteristic can be inferred from signals from the acoustic sensor (4) and the pressure sensor (61). The device may also comprise a set of contact electrodes (3) to provide additionally ECG functionality.
