本研究针对心电图（ECG）心律失常人工诊断效率低、易出错的问题，开发了一种将ECG信号转化为二维图像并结合EfficientNetB0与Transformer的混合深度学习框架ECG-CNNTX。该模型在MIT-BIH数据库的PVC检测中达到99%的准确率，并通过Grad-CAM实现可视化解释，为临床提供高精度 ...

In tracing "a" of Figure 1, there seems to be only one P wave in front of each QRS complex, suggesting sinus rhythm. However, during the compensatory pauses after the PVCs (↑) in tracing "b," there ...

Wide QRS regular tachycardia is present in Figure 1. No definite P waves are identifiable. There is one PVC in the lower tracing. During the compensatory pause, there is definitely a P wave (↓ on ...
