[Short-term pharmacological block of the atrioventricular node in the diagnosis of cardiac arrhythmias].
73 patients were examined with the aim of establishing the clinical importance of the method of short-term pharmacologic blockage (SPB) of atrioventricular node (AVN) in the diagnosis of paroxysmal tachycardias, latent forms of ventricular pre-excitation and attached forms of parasystole. SPB AVN was performed as an intravenous bolus of adenosinetriphosphate (ATP) in graded doses (10-30 mg) with simultaneous ECG recording. If adverse effects of ATP occurred its reinfusions were tapered to a dose of 5-10-15 mg in the presence of preliminary intravenously administered verapamil (5 mg). Objective nature of the diagnostic information obtained by using SPB AVN in the above outlined cardiac arrhythmias is analysed.
