Abstract

The 12-lead electrocardiogram is the most widely used first line test for heart disease, but expert review is a bottleneck in busy clinics. This paper compares two deep models for detection of myocardial infarction against confirmed normal recordings on the PTB-XL corpus. The first is a 1D Residual Network with eight residual blocks over the raw signal. The second is a convolutional front end followed by a bidirectional LSTM with attention pooling. Both models are trained end to end on the standard PTB-XL split with light augmentation and class weighted cross entropy. On the held out fold the ResNet reaches 0.9630 accuracy and AUROC 0.981, and the recurrent model reaches 0.9520 accuracy and AUROC 0.981. Both improve over a strong handcrafted feature baseline. The models fit on a single RTX 6000 Ada GPU and train in under two minutes each.
