Key result
Combining clinical features with ECG differentiated the origins of focal atrial tachycardias with 93% accuracy for LSPV vs. LAA and 82% accuracy for RSPV vs. SVC.
Why the study?
Does combining clinical features with ECG improve the accuracy of localizing focal atrial tachycardias compared to ECG alone in patients undergoing electrophysiological study?
Population
194 patients who underwent electrophysiological study for focal atrial tachycardia
Comparison
Electrocardiography combined with clinical… vs Electrocardiography (ECG) alone

Does combining clinical features with ECG improve the accuracy of localizing focal atrial tachycardias compared to ECG alone in patients undergoing electrophysiological study?
Combining clinical features and Holter monitoring with ECG improves the diagnostic accuracy of localizing focal atrial tachycardias originating from adjacent structures.
Uhm et al. (2013) conducted an observational in Focal atrial tachycardias (n=194). ECG combined with clinical features vs. ECG alone was evaluated on Accuracy in differentiating the origin of focal atrial tachycardias. Combining clinical features with ECG differentiated the origins of focal atrial tachycardias with 93% accuracy for LSPV vs. LAA and 82% accuracy for RSPV vs. SVC.
