Abstract
Objective: To investigate the diagnostic value of the VT score on a 12-lead electrocardiogram in determine the mechanism of wide QRS tachycardia.
Results: During the period from May 2017 to September 2023, we used the VT score to differentiate wide QRS tachycardia in a total of 58 patients, the results of sensitivity and specificity were the accuracy with VT ≥ 1 is 88.1%, 62.5%, and 81%, respectively. Especially in our study, VT score ≥ 3 points, with results showing that the sensitivity, specificity, and accuracy were 33.3%, 100%, 51.7% respectively. Score ≥ 3 points specificity in our study is almost absolute specificity for a diagnosis of ventricular tachycardia.
Conclusion: Regarding the diagnostic value of VT score in differentiating the mechanism of wide QRS tachycardia: The VT score used 7 features on the electrocardiogram with sensitivity, specificity, and accuracy. 88.1%, 62.5%, 81% respectively with VT score ≥ 1
