Giá trị dự đoán của biến thiên khoảng ghép trong chẩn đoán phân biệt vị trí khởi phát ngoại tâm thu thất từ đường ra thất phải và đường ra thất trái

Key Result

Coupling interval variability was significantly higher in premature ventricular contractions originating from the left ventricular outflow tract compared to the right ventricular outflow tract.

Key Points

• The aim was to evaluate the predictive value of gap variation in differentiating the origin of ventricular premature beats from right and left outflow tracts.
• Data from 87 patients who underwent successful radiofrequency catheter ablation in 2019-2020 were analyzed.
• Gap variation was calculated as the difference between the maximum and minimum confidence intervals.
• Statistical analysis was performed to determine the significance of differences between groups.
• Gap variation was significantly higher for ventricular premature beats originating from the right outflow tract compared to the left (p < 0.05).
• The findings indicate a strong potential for using gap variation in clinical decision-making.
