### General

A simple script to display ECG waveform graphs based on data previously collected from the ECG recorder. The script accepts a CSV file whose first column contains time samples and the second column contains ECG signal samples. The signal is filtered using a Butterworth bandpass filter.

### Usage

```

positional arguments:

  fname                 File path

options:

  -h, --help              show this help message and exit

  -fs FS                  Sampling frequency; default 1000Hz

  --delimiter DELIMITER   Columns delimiter; default ','

  -tstart TSTART          Signal recording start time in seconds; default 0

  -tstop TSTOP            Signal recording stop time in seconds; default signal duration time

  --lowcut LOWCUT         Butterworth filter lowcut frequency [Hz]; default 0.5Hz

  --highcut HIGHCUT       Butterworth filter highcut frequency [Hz]; default 150Hz

  -dt DT                  Displaying window width as time in seconds; default 5s

```

### Requirements

The script uses external libraries: matplotlib, scipy and numpy.

### Demo

```

python ecg_monitor.py 'ecg.csv' -tstart 140

```






```

python ecg_monitor.py 'ecg.csv' -tstart 100 --lowcut 0.1

```



Too low filter lowcut value - low frequencies components (breathing chest movements) causes signal floating.
