DIAGNOSTICS AND TREATMENT OF PAROXYSMAL NODAL RECIPROCATING TACHYCARDIAS WITH TRANSESOPHAGEAL STIMULATION
Abstract
The aim of the study was to estimate the effectiveness of transesophageal electrophysiologic assay in diagnostics of paroxysmal nodal reciprocating tachycardias compared to intracardiac electrophysiologic assays and working out treatment strategies in patients with supraventricular paroxysmal tachycardias.
We have studied 100 patients with nodal reciprocating tachycardias. Diagnostic transesophageal stimulation was performed in all, and intracardiac electrophysiologic assays to elaborate the nature and mechanism of tachycardias in 85. Effective antiarrhythmic treatment was adjusted by using transesophageal electrophysiologic assays. Series of tests supposed the usage of all 4 classes of antiarrhythmic drugs.
Comparative analysis of the data obtained showed the in most cases there was no reliable difference between anterograde functional and effective refractory periods of various parts of the conductive system, as measured by transesophageal and intracardiac electrophysiologic assays. We have worked out principal electrophysiologic criteria of diagnosing paroxysmal nodal reciprocating tachycardias based on transesophageal assays.
Individually effective antiarrhythmic treatment was managed in 96% cases. Class I drugs proved most effective (in 70% patients), and propranolol had the best individual result in the daily dose of 20-40 mg (in 50% patients).
