Correlation of AI-enabled ECG model output with clinical, routine ECG, and echocardiographic parameters. (A) Correlation plot between clinical and echocardiographic parameters and AI-ECG model output. (B) Plot of individual parameters correlated with AI-ECG model output, grouped by whether patients developed AF after HCT. ∗∗∗P < .001; ∗P < .05. LAVI, left atrial volume index; LVEDDi, left ventricular dimension at end diastole index; LVMI, left ventricular mass index; PR, PR interval; QTC, corrected QT interval; TR MAX Vel, tricuspid regurgitant maximum velocity.
