This reference design implements a compact hardware-based circuit to detect the pacemaker pulse during ECG measurement. It provides indication of valid pace signal through a flag and onboard LED. This design enables the user to configure various parameters of the pace signal (amplitude, rise time, pulse duration, polarity) with software using an onboard DAC. The measured values can be read through an onboard ADC. The Pace signal is extracted, amplified, and conditioned from the noisy ECG signal on the board. It adds the Pace detection feature while used in conjunction with TI’s ADS129X series of devices.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
