How to Graph an Electrocardiogram (EKG) in Python (Complete Beginner)
Create a graph of heartbeats from an EKG (as in voltage data from heart muscle contractions) in Python. This tutorial assumes you are new to Python and coding in general.
Kaggle notebook with Python code: https://www.kaggle.com/code/protobioe...
We use the free coding website, Kaggle, to open a file of electrocardiogram (EKG) data and create a graph of real heartbeats. Once you have a free Kaggle account, you can write Python or R code directly on the website without having to download or install anything. Kaggle also has thousands of free datasets to analyze and play around with. Start coding here: https://kaggle.com

*Overall Steps for Graphing an EKG*
1. Get EKG data
2. Import libraries that help open and graph the data (Pandas, Matplotlib)
3. Open the data with the Pandas library
4. Get one of the voltage columns from the data
5. Graph the voltage data with Matplotlib's "plot()" function
6. (Optional) Add a title
