ECG waveform generator for Matlab/Octave

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.

Estimating Activity from Instantaneous Heart Rate

Using only a heart rate time series, it is possible to measure a number of features that reflect the level of physical activity. Here we provide software for deriving an "activity index" based on measurements of mean heart rate, total powe…
