Objective:

To develop an efficient deep learning model based on surface and esophageal ECG for the identification and classification of paroxysmal supraventricular tachycardia (PSVT), specifically targeting slow-fast atrioventricular nodal re-entrant tachycardia (S-F AVNRT), orthodromic atrioventricular reentrant tachycardia involving the left accessory pathway (AVRT-L), and orthodromic atrioventricular reentrant tachycardia involving the right accessory pathway (AVRT-R).

Approach:

Key Findings:

• The deep learning model demonstrated high accuracy and stability in classifying PSVT types.
• The model was trained on a dataset split at the patient level to prevent data leakage.

Interpretation:

The integration of surface and esophageal ECG data with deep learning may enhance the accuracy of PSVT classification.

Limitations:

• The study is retrospective and may have inherent biases.
• The model's performance needs validation in larger, diverse populations.

Conclusion:

The study presents a novel deep learning approach for PSVT classification, potentially improving diagnostic accuracy.
