Cardiorenal Interorgan Assessment via a Novel Clustering Method Using Dynamic Time Warping on Electrocardiogram: Model Development and Validation Study

Cardiorenal Interorgan Assessment via a Novel Clustering Method Using Dynamic Time Warping on Electrocardiogram: Model Development and Validation Study

By treating each ECG record as a singular data point, we can perform DTW on the ECG as a time series. DTW is a technique that calculates the optimal match between given sequences (it can be thought of as clustering curves via distance rather than individual data points). This way, different clusters of ECG records can be formed and then analyzed for disease endpoint incidence, cluster stability, and other performance metrics.

Then, potentially eligible participants were invited to a preparticipation health screening conducted by a physician with the assistance of a nurse. The preparticipation health screening consisted of a thorough interpretation of an individual’s medical history, clinical status, resting blood pressure, resting ECG, and body mass and height measurements.
