Laser Application To Arrhythmia Surgerysinus Node Modification With NdYAGr Laser

Summary form only given. As the treatment of inappropriate sinus tachycardia, P-drenoreceptor blockade therapy is the most common method for pharmacological heart rate control, but it is occasionally limited by side effects of the drugs, especially in patients with cardiac dysfunction. On the other hand, cryoablation or surgical exclusion of the sinu node have not been accepted, generally for their necessity of permanent pacemaker implantation.
