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 ...

《ECG-LM: Understanding Electrocardiogram with a Large Language Model》一文开发了多模态大语言模型（ECG-LM）用于处理心电图（ECG）信号。该模型在心血管疾病检测等任务上表现出色，能有效捕捉 ECG 特征，为疾病预测和问答等应用提供支持，具有重要研究价值。 ### 引言 心电 ...

A narrow QRS tachycardia at a rate of 105 beats/min. is present. No P waves are identified in front of the QRS complexes, suggesting accelerated AV junctional rhythm. However, there are two PVCs.
