The electrocardiogram (ECG) is a clinical tool used by practitioners to evaluate a patient's myocardial health. In addition to a resting state, the robust ECG signal can be collected during physical activity. This feature of ECG allows the practitioner to diagnose heart pathologies that only occur during exercise. For your BIOE 1331 project, you are tasked with writing a MATLAB program to analyze two ECG signals, and form a conclusion as to the circumstances under which the ECG recording was performed. You should be able to conclude with valid reasoning which patient was exercising, and which patient was at rest.

It is mandatory that you include the following in your program: 1. Define a time series for both patients. 2. Plot the raw signals on a reasonable time scale.

3. Filter the power line noise from the signals. 4. Plot the filtered signals on a reasonable time scale.

5. Detect, mark, and plot all R waves in each signal with reasonable accuracy. 6. Calculate average pulse rate across the entirety of both acquisitions.

7. Calculate the R to R intervals for each signal. 8. Plot the heart rate variation for each signal.

In addition to your MATLAB code, you will need to write a project report describing what you did, how you did it, and what your final conclusions are. Your report should include the following sections.

 Introduction/Background

 Methods  Results

 Discussion

 Conclusion
