[Electrophysiologic study and endocardial ECG mapping in the detection of causes of heart rhythm disorders].
Accessory pathways and ectopic heart focuses tachycardias are often cause of tachycardias. AV reentry tachycardias are great diagnostic and therapeutic problems. Using the electrophysiological investigation and ECG mapping, there is possibility to find out abnormal pathways and ectopic atrial and ventricular focuses. In electrophysiological investigations we can use bipolar, threepolar and multipolar electrodes and mapping electrodes, as well. The ablation catheter is introduced by transveins way in electrophysiological investigation of right atrium and ventricle, and via the femoral artery to the left atrium and ventricle. We investigated 45 patients, who are hospitalised at the Cardiology clinic Ependorf, of the University in Hamburg Accessory pathways were found out in 37 (82.22%) patients. Successful RF catheter ablation was done in 34 (91.89%) patients and unsuccessful in 3 (8.10%). Ectopic focuses were found out in patients with left ventricle aneurysm. It was indication for aneurysmectomia in two cases and for implantation of antitachycardia pacemaker in one case.
