CardioNet received FDA clearance for a remote cardiac-monitoring device in 2002. The device automatically and wirelessly transmits arrhythmic signals to the monitoring center. In 2003, the FDA approved the first Bluetooth wireless medical device, the Serial Port Adapter developed by Swedish Bluetooth company ConnectBlue. The device lets operating room equipment communicate, enabling wireless printing of electrocardiograms or transmission of medical images.
