摘要
A circuit and method for radiotelemetry of an esophageal pH signal in an electrocardiogram (ECG) signal radiotelemetry system includes esophageal and reference pH electrodes (16 and 17) connected to a pH meter (15) for monitoring esophageal pH and generating a signal proportional thereto and a waveform converter circuit (12) for converting the same to a signal whose waveform is similar to an ECG waveform and one of whose parameters, such as frequency, is proportional to esophageal pH. A conventional ECG radiotelemetry system (13) includes an ECG signal transmitter (31) receiving and broadcasting the converted signal to a remote ECG signal receiver (32). A display (14) receives the demodulated converted waveform from ECG signal receiver (32) and displays indicia of esophageal pH.
