Abstract
Atrial Fib & Atrial Flutter are two kind of atrial arrhythmia with mechanism of reentry.Site of origin of atrial Fib in 90% cases is PVs. Also around the CS-OS and SVC and IVC junction to RA could be the origin of APCs initiating Atrial Fib. Atrial Flutter (AF) has a macrorentery circuit in the RA. Objective: RFCA is applicable in the patients with A.F and A.Fib with single site lesion.We studied 3 patients with AF and A.Fib , after locating CS and halo Catheters we induced AF which converted to A.Fib before sinus rhythm appearance. Prominent APCs with a little different AA intervals were seen around CS OS.APCs .RF energy was delivered to the isthmus between CS OS and IVC , and bilateral block was showed with CS and Halo catheter pacing. Then we could not induce AF, also no APCs was seen.After 12 to 6 months fallow up no patients experienced any arrhythmia without any anti arrythmic agent , neither 48 hours holter monitoring disclosed any arrhythmia. Coincidence of AF and A.Fib is common . In these cases the site of origin of A.Fib could be the isthmus region and RFCA of these area would eradicate both of them.
