The architecture features parallel processing through two specialized attention mechanisms: a channel attention submodule that adaptively weights clinically significant ECG leads using complementary feature pathways, working in concert with a spatial attention submodule that captures essential morphological patterns through synergistic multi\u2010scale pooling and convolutional feature extraction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In a comparative study of nine classical CNNs, ResNet50 demonstrated superior performance, achieving the highest sensitivity and specificity and validating the efficacy of residual learning for this task. The proposed CSPANet, integrating our novel channel and spatial parallel attention (CSPA) mechanism, achieved a test set accuracy of 92.6%, sensitivity of 79.0%, specificity of 95.0%, and precision of 79.7%, surpassing all other representative attention mechanisms. Ablation studies confirmed the individual and synergistic contributions of the CSPA and Stem modules, with their combined integration yielding the most significant performance gains, including an 11.7% increase in sensitivity and an 8.8% increase in precision over the baseline ResNet20 model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>CSPANet's ability to differentiate CAP and AVNRT from sinus rhythm ECGs offers a transformative clinical tool, facilitating optimized ablation planning and enhancing procedural safety.
