A monitoring system including a master device adapted for wireless communication with at least one slave device having a sensor. The sensor of the at least one slave device is adapted for acquiring a physiological signal. The master device is adapted for providing a synchronization signal to the at least one slave device and instructing the at least one slave device to acquire the physiological signal based on timing instructions. The at least one slave device is adapted for acquiring the physiological signal by means of the sensor according to the received timing instructions and transmitting the acquired physiological signal wirelessly to the master device. The master device includes a processor for processing the synchronized, physiological signals acquired by sensors synchronized via wireless communication.
