Artificial Intelligence-Enhanced Electrocardiography and Health Records to Predict Cardiac Arrest.

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) is a public health burden with the majority occurring in the general population for whom there is no firm strategy to predict risk. OBJECTIVES: The authors evaluated whether artificial intelligence enhanced electrocardiography (ECG) and clinical information from electronic health records (EHRs) can stratify risk of OHCA in the general population. M...

Minority class-aware multiclass arrhythmia detection using conditional GAN augmentation.

The detection of cardiac arrhythmias from electrocardiogram (ECG) signals is essential for preventing sudden cardiac deaths. However, model performance on minority classes, such as supraventricular (S) and fusion (F) beats, which make up less than 3% of samples, is severely hampered by severe class imbalance in benchmark datasets like MIT-BIH. Conventional methods, such as basic GAN-based augmenta...
