The First Demonstration Of 3Ding Mapping System in Gansu Province
February 21,2020

On May 2017, Dr Jing Nie from Tianjing Medical University General Hospital was successful cured a patient in atrial premature originated from left superior pulmonary vein and two patients in premature ventricular contractions from ventricular outflow tracked by 3Ding Mapping System and Catheters RF Ablation. It is the first time of 3Ding Mapping System which is used in Circumferential Pulmonary Vein Isolation in Gansu province.

12 Leads Electrocardiogram before Operation

Atrial Fibrillation Triggered by Premature Atrial Contraction

The earliest RA activation is in the high-interventricular septal. The ablation catheter potential is behind of CS12 to prompt activation through Bachmann to RA.

Mapping for LA

The earliest activation is in the top of LSPV so isolate the left pulmonary vein.

Intravenous infusion of isoproterenol after ablation is observed

The result without AE, AT, AF symptoms
