ECG Small Signal Generation and Analysis

应用文章

Electrocardiogram (ECG or EKG) is the most common way to identify various ailments, especially when the ailment is related to the heart. Today there is a wide array of cardiac equipment that displays and interprets ECG signal patterns and medical equipment. Designers need a flexible, reliable and accurate way to seamlessly generate ECG signal patterns to verify their designs.

Small Signal Generation Solution

Key factors to consider when generating ECG signals, including:

  • Low amplitude signal ± 1 mV or ± 0.5 mV;
  • Large offset due to half potential developed at electrode;
  • System noise (50/60 Hz) from the power lines which forms the common mode signal; and
  • Complex ECG signal pattern.

The firmware design of the ECG equipment can resolve the offset developed by electrode and common mode signal from power lines. The best solution to generated clean, low amplitude ECG and create complex ECG signal pattern is to use a waveform generator.
