[Ablation of ventricular tachycardia in thoracotomy without artificial circulation].

Seventeen patients were operated on for ventricular tachycardia (VT). Closed heart radical surgeries destroying the arrhythmia substrate were made without employing extracorporeal circulation. A VT episode was inducible in 16 (94%) patients for VT intraoperative mapping.

Cryosurgery in tachycardia treatment.

Cryosurgical techniques have become established and acceptable therapy in the treatment of resistant arrhythmias. In this report, both experimental and clinical data are presented describing the results of various cryosurgical techniques used at the Cardiac Rhythm Disturbance Center in Lithuania, USSR.

[Electrodes for epicardial electrical mapping].

Medical-technical characteristics of electrodes for epicardial mapping are examined. Most electrodes are bipolar. The differences between them lies either in the contact configuration or in the fixation mode.
