Notebook Difficulty Level: ★★☆☆☆
Like described on another Jupyter Notebook entitled “Event Detection – R Peaks (ECG)” , periodicity is one of the distinctive characteristics of electrocardiographic signals.
For studying periodicity it is necessary to detect a specific event in all the cardiac cycles. The QRS complex is the most prominent structure of ECG signal, being the event commonly chosen.
After detecting each R peak the time interval between them can be determined. With each time interval a time series may be generated, named Tachogram .
Essentially, the tachogram describes how the cardiac period changes along time and is the inverse of heart rate time series.
Here, it will be presented a simple way to generate a tachogram from the acquired data.
