Clean an ECG, find each heartbeat, classify it with a small network, and test on patients the model never saw.

What does an ECG show?See the parts of a heartbeat and why some beats are different

1Remove ECG Baseline WanderClean the signal

2Slope Energy for QRS DetectionMake every beat stand out

3Pick R Peaks with an Adaptive ThresholdFind every heartbeat

4Cut a Window Around Every BeatOne example per heartbeat

5Per-Class Sensitivity and PrecisionScore every class

From Beats to a ClassifierSee how your functions fit together before the notebook

Build and Honestly Test a Heartbeat ClassifierDetect beats in 44 real recordings, train a small CNN, and see what changes when the patients are new
