Coupled Oscillator Representation of Cardiac Electrical Activity The Synthetic ECG generation process begins with cardiac dynamics as network of biological oscillators. This network includes the Sinoatrial node (SA), the Atrioventricular (AV) node, and the His–Purkinje (HP) complex, each exhibiting an intrinsic rhythm and distinct electrical properties. Their ordered interaction gives rise to the heart's electrical signaling, guiding how these impulses propagate and enabling

A Brief Overview of Synthetic Data Synthetic data is information that is artificially generated by computer algorithms rather than collected from real-world events or individuals. While it contains no real personal records, it accurately mimics the mathematical patterns, distributions, and correlations of the original dataset. In the context of machine learning, this is typically achieved using generative AI techniques. For example, instead of relying on a database of highly
