Abstract
Purpose. The aim of the study was to compare the accuracy of non-invasive topical diagnosis of ventricular arrhythmias and the data of intracardiac mapping.
Materials and methods. Thirty-six patients (16 male and 20 female) 44.2±7.6 years of age having ventricular ectopic arrhythmias were included in retrospective study. Patient selection was based on the results of intracardiac mapping in such a way to form six equal groups by six patients in each. Before the ablation procedure, non-invasive mapping was performed in all patients. After the procedure, the accuracy of non-invasive mapping was evaluated in comparison with invasive procedure results.
Results. Non-invasive mapping allows to localize the ectopic foci in the same anatomical zone with successful ablation site in 24 (67 %) of cases (p=0.0001 in comparison with invasive mapping). The correct localization of the ectopic foci using traditional topical diagnosis algorithm was possible in 23 (64 %) of cases (p=0.0001 in comparison with invasive mapping and p=0.805 in comparison with non-invasive mapping). Statistically insignificant bias of greater accuracy of non-invasive mapping in case of outflow tract location of the ectopic foci was registered.
Conclusion. The accuracy of non-invasive mapping varies from 50 to 83 % depending on ectopic focus location (mean 67 %) that is comparable with traditional electrocardiographic topical diagnosis algorithm accuracy.
