I.2. Методика **эндокардиального электрофизиологического исследования** и радиочастотной абляции неишемических желудочковых нарушений ритма

Под местной анестезией 0,5% раствором новокаина пунктировали правую и левую общие бедренные вены. Под рентгенологическим контролем через интродъюсер 8 Fr, установленный в левой бедренной вене, **квадриполярный диагностический катетер** 5-6 Fr (Medtronic, Cardiorhythm, Mpls, USA) размещали в верхушке правого желудочка.

The performance of **catheter ablation** requires skills detailed previously as necessary for the performance of **diagnostic electrophysiologic testing**. The indications, contraindications, and complications for catheter ablation are largely derived from the ACC/AHA Guidelines for Clinical ****Intracardiac Electrophysiologic**** and Catheter Ablation **Procedures** (17).

Иногда - даже просто "electrophysiology study" (мол, "внутрисердечность" здесь и так понятна...):



Electrophysiology (EP) Study and Endocardial Catheter Ablation

What is an EP Study?:

An electrophysiology (EP) study is a method for assessing the heart’s electrical function. During the study a specialized physician, called a cardiac electrophysiologist, inserts electrode catheters (long and flexible wires) into the veins and guides them into the heart. This is performed on a special sterilized room and is performed under sedation or general anesthesia. The catheters are inserted through the groin and shoulder veins under local anesthesia (numbing medicine). Once inside the heart, this catheter can sense electrical impulses in various areas. The catheters can also be used to stimulate different parts of the heart.

...and 10 patients underwent 12 **intracardiac electrophysiologic investigations**. Left atrial, right atrial or biatrial P wave abnormalities were present in 60% of the surface ECGs. Evidence of abnormal AV node or infranodal conduction was present on **intracardiac electrophysiologic study** or surface ECG in 27% of patients. Atrial flutter or fibrillation was induced by single atrial extra stimuli in 10 of the 12 **intracardiac electrophysiologic studies**. ...
