Collect and prepare ECG signals
Use a licensed ECG dataset (for example PhysioNet or MIMIC‑ECG), convert raw waveforms to a consistent sampling rate and annotate beats or rhythms with clinician labels.
Analyse ECG signals. Prioritise clinical review.
ECG analysis systems learn to detect rhythms or pathologies from ECG waveforms and require careful signal preprocessing, patient-aware splitting, and clinically meaningful metrics. Common error cases include noisy leads, missing channels, labelling disagreement among clinicians and demographic biases in the training set.

ECG analysis systems learn to detect rhythms or pathologies from ECG waveforms and require careful signal preprocessing, patient-aware splitting, and clinically meaningful metrics. Common error cases include noisy leads, missing channels, labelling disagreement among clinicians and demographic biases in the training set.
A proposed application: a clinical‑review assistant that highlights ECGs with suspected abnormal rhythms for cardiologist review. This extension must keep a clinician in control and is not implemented in the supplied starter code.
Use a licensed ECG dataset (for example PhysioNet or MIMIC‑ECG), convert raw waveforms to a consistent sampling rate and annotate beats or rhythms with clinician labels.
Compute time‑domain and frequency‑domain features, or prepare fixed-length waveform windows for a deep model; handle missing leads and noisy segments explicitly.
Split by patient, train a baseline model and report sensitivity, specificity and AUC; inspect failure modes by rhythm type and noise level.
Provide a UI that shows the ECG trace, model confidence and a way for clinicians to correct labels; add monitoring for drift and alerting.
The supplied starter generates a synthetic classification dataset with sklearn.datasets.make_classification (800 samples, 10 features), trains a Pipeline with StandardScaler and RandomForestClassifier, then prints a sklearn classification report on a random test split. It does not load ECG waveforms, perform signal processing, or use clinical labels.
model = Pipeline(
steps=[
("scale", StandardScaler()),
("classifier", RandomForestClassifier(n_estimators=250, random_state=RANDOM_STATE)),
]
)
model.fit(X_train, y_train)
predictions = model.predict(X_test)
print(PROJECT_NAME)
print(classification_report(y_test, predictions))The starter uses synthetic tabular features from make_classification rather than ECG waveforms; it lacks any signal preprocessing, beat/rhythm labelling, patient‑level splitting, and clinical evaluation metrics. Results from this code do not validate ECG detection or diagnosis.
Proposed extension: replace the synthetic data with a curated ECG corpus (PhysioNet or MIMIC‑ECG), add signal preprocessing and beat/rhythm labelling, train a waveform model or feature‑based classifier, and produce a clinician review UI that reports sensitivity and specificity for target rhythms.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
