About this trial
Study of ECG and electrophysiological criteria which discriminate right versus left septal AP (both posteroseptal and anteroseptal AP). Both manifest and concealed APs will be considered .
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
All patients with suggested septal AP (both manifest and concealed AP) undergoing electrophysiological study and ablation in EP cath lab in cardiology department, Assiut University Heart hospital.
Disqualifiers
Patients with redo AP or failed ablation.
Patients with more than one AP.
Congenital or structural heart diseases.
Trial population
All patients with suggested septal AP (both manifest and concealed AP)

Trial outcomes
Primary outcomes
1
Differentiate right from left septal manifest accessory pathway using ECG
Onset of delta wave in each lead will be measured from the onset of the earliest delta wave in any of the ECG leads.The polarity of the delta wave will be measured within the initial 20 msec of the preexcitation and will be classified as positive (+), negative (-), or isoelectric (+-). Localization of the site of the accessory pathway will be done using Arruda's algorithm and Fitzpatrick's algorithm
