Abstract
A pacemaker and heart monitoring and transmitting device connects by telephone to a remote receiving station by both cradle coupling to a patient telephone handset and hands-free communication modes. The device collects an analog patient signal, including electrical EKG activity and pacemaker stimulation pulse width information, and applies such analog signal to a microcontroller executing conversion to digital form and application of digital signal processing (DSP) to produce a digitally generated tone representing patient EKG and stimulation pulse width information for delivery by telephone connection to a remote receiving station. The device further reacts to DTMF tones originating from the remote station to alter operation including increase or decrease in speaker volume, activation of a patient alert signal, initiation of hands-free mode, and a variety of other command features.
