Abstract
ECGwaveGen generates a synthetic ECG signal with user-settable heart rate, signal duration, sampling frequency, QRS amplitude and duration, and T-wave amplitude. The synthesized ECG is not intended to be highly realistic. The primary application is for testing the fidelity of analog signal-processing components of cardiac monitors and similar instruments.
Description
ECGwaveGen generates a synthesized ECG signal with user-settable heart rate, signal duration, sampling frequency, QRS amplitude and duration, and T-wave amplitude; it uses QRSpulse to create premature beats followed by compensatory pauses.
The algorithm is based in part on the algorithm described in "A real-time microprocessor QRS detector system with a 1-ms timing accuracy for the measurement of ambulatory HRV" [1], in which the authors describe an artificial ECG signal based on the standard test waveforms specified in ANSI/AAMI EC13:1992 (American National Standard: Cardiac Monitors, Heart Rate Meters, and Alarms) [2].
The synthesized ECG is not intended to be highly realistic; the primary application is for testing the fidelity of analog signal-processing components of cardiac monitors and similar instruments, using an ECG-like signal with well-defined characteristics.
EC13 also specifies the use of a specific set of non-synthesized waveforms available on PhysioNet [3]. Potential users of ECGwaveGen may also wish to consider ECGSYN, which generates realistic ECG signals and provides a somewhat different set of capabilities [4].
