1. A method for adjusting a VAD device parameters using a wearable device placed on a patient's arm comprising steps of:
acquiring a set of signals from sensors in said wearable device, wherein said sensors comprise at least one of the following sensors: pressure sensor placed on the radial artery, photopleythysmograph (PPG) sensor, oxygen saturation level (SpO2) sensor, accelerometer, and temperature sensor;
acquiring signals from sensors within an implanted device, wherein said implanted device is selected from a group consisting of a defibrillator, pace-maker, cardiac resynchronization therapy-CRT, vagal stimulator or any combination thereof;
computing using a processor of the wearable device at least one quality metric based on the signals acquired from said wearable device and said implanted device; and
adjusting at least one VAD parameter so as to optimize at least said one quality metric, wherein said VAD parameter being optimized includes at least the VAD rotational speed or frequency.
