Background: Atrial Fib and 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. Method: 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 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. Result: After 12 to 6 months fallow up no patients experienced any arrhythmia without any antiarrythmic agent, neither 48 hours holter monitoring disclosed any arrhythmia. Conclusion: 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 this area would eradicate both of them.
