The present invention relates a cardiovascular monitoring device including a first housing and a second housing, a circuitry with at least a processor, distributed in the first and second housings to form a first unit and a second unit, for providing functions of blood pressure and electrocardiogram measurements, an inflatable cuff connected with the first housing for being used during blood pressure measurement, and at least two electrodes, at least one of which is a dry electrode and mounted on the second housing for contacting the users hand. The processor can detect an activation of the functions of blood pressure and electrocardiogram measurements, and based on a detecting result, trigger the device to enter different operation modes. The processor can further provide diastolic and systolic blood pressures when the blood pressure measurement function is activated, and provide a heart rhythm information when the electrocardiogram measurement function is activated.
