    Determining the incidence of SAN and AVN dysfunction before and after percutaneous ASD closure Comparing ECG and EP parameters of SAN and AVN before and after percutaneous ASD closure

Study Arms (1)

Incidence of AV node dysfunction after ASD Closure

EXPERIMENTAL

Determining the incidence of SAN and AVN dysfunction before and after percutaneous ASD closure Comparing ECG and EP parameters of SAN and AVN before and after percutaneous ASD closure

Procedure: Electrophysiology study of heart

Interventions

The procedure will be done comparatively for each patient; before the device placement and immediately after the procedure. This will be done approaching the same sheath that is placed for ASD device closure (the right femoral vein). Only one quadripolar EP catheter will be used, it will be placed in high right atrium then at His bundle. The EP study will include: Assessment of SAN function using cSNRT (through HRA pacing) Assessment of AH and HV intervals (through His bundle EGM) Assessment of antegrade AVN RP (refractory period) and AVN WP (Wenckebach point) through extra-stimuli and incremental atrial pacing. Any inducible arrhythmia will be reported
