The authors analyzed paroxysmal atrioventricular blocks which were not frequency-dependent. It was a clinical, electrocardiographic and electrophysiological evaluation. The authors draw attention to the pitfalls of diagnosis and emphasize that the problem of interpretation of atrioventricular (intraventricular) conductivity is unequivocally associated with the problem of indication of permanent cardiac pacing. Based on their own experience, the authors describe the procedure used for establishment of the diagnosis of paroxysms of atrioventricular blocks. What are the main conclusions? 1. In the first place it is necessary to pay attention to the history of syncopes. 2. On the conventional ECG we find usually disorders of atrioventricular and intraventricular conductivity. 3. Electrophysiological examination should be always supplemented also by pharmacological intervention, using Gilurytmal by the i.v. route.
