Beschreibung

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.

Eigenschaften

• Programmable thresholds for detecting : rise time (30 μs to 200 μs), amplitude (8 mV to 700 mV), duration (0.1 μs to 2000 μs) and polarity of pace pulse
• Availability of measured parameters and conditioned pace signal on I2C bus for further analysis and processing conditioned pace signal on I2C bus for further analysis and processing
• Interface with TI’s ADS129X series of ECG front-end devices
• Enables identification of various types of pacemaker signals
• Compact form factor (29 mm × 35 mm)

Typische Anwendungen

• Electrocardiogram (ECG)/Wearable fitness and activity monitor
