ABSTRACT:
A mobile diagnosis device comprised of an ECG unit (1) to record an ECG signal (55), with the ECG unit (1) being connected or connectible to two or more ECG electrodes (27, 28) to dissipate electrical signals from a patient's body, and comprised of a pulsoximetry unit (2) for simultaneous recording of a volume pulse signal (56), with the pulsoximetry unit (2) comprising at least one light source (17, 18) and at least one light sensor (20) for optical measurement of blood perfusion in the vascular system of a patient's body tissue, and comprised of a program-controlled evaluation unit (4) to evaluate the ECG signal (55) and the volume pulse signal (56). To provide such a diagnosis device that is suitable for auto-diagnosis of cardiovascular diseases, the device proposes that the evaluation unit (4) be appropriately equipped to allow for automatic recognition of R peaks (57) in the ECG signal (55), automatic recognition of extreme levels (58) in the volume pulse signal (56), and for determination of the time difference (60) between an R peak (57) and a successive extreme level (58) in the volume pulse signal (56). Furthermore, the evaluation unit (4) can be appropriately equipped to allow for determination of the time difference (61) between the main and secondary peak values (58, 59) in the volume pulse signal (56).
