This project does a couple of things:
1) Loads in and plots ECG data from three areas: resting, box breathing, and post-exercise
2) Develops an algorithm to detect peaks in data, isolating heartbeats from noisy signals
3) Builds histograms/box plots comparing heart rate distributions for the three conditions
4) Calculates heart rate and plots voltage change rates
5) Utilizes a two-sided t-test comparing resting vs. exercise heart rates to confirm that exercise significantly affects heart rate.
