Abstract
122 persons who had participated in the Chernobyl nuclear power station disaster control were passed through ECG examinations, as a result of which susceptibility to bradycardia was revealed. To exclude a marked vagal influence on the myocardium, orthostatic, atropine and ephedrine tests were performed. Weakened reactions to atropine and ephedrine indicated a secondary vagotomy caused by the lowered sensitivity of beta-adrenoreceptors.

Abstract
The aim of this study was to compare the incidence and predictive factors of complete atrioventricular block (AVB) and permanent pacemaker implantation (PPI) after transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement (SAVR).
No data exist on the need for PPI after TAVI versus SAVR in patients with similar baseline electrocardiographic (ECG) findings.
A total of 411 patients with severe aortic stenosis (AS) and no prior pacemaker who underwent TAVI with the balloon-expandable Edwards valve (Edwards Lifesciences, Irvine, California) were matched (1:1) with 411 elderly patients with severe AS who underwent isolated SAVR on the basis of baseline ECG findings. The incidence, reasons, and predictive factors for PPI within 30 days after the procedure were compared between groups.
Mean age was similar in both groups (p = 0.11), and the TAVI group had a higher Society of Thoracic Surgeons score (p
