WebJun 10, 2024 · Corrected SNRT was measured as SNRT minus the baseline sinus BCL. Atrioventricular nodal Wenckebach period is determined by pacing at progressively rapid fixed cycle lengths, and it is reached when there is atrial capture without capture of the His bundle or ventricle. WebThe QT intervals were rate-corrected with Bazett's formula, and JT intervals also were rate-corrected by analogy using the formula JT/RR 1/2, ... The sinus node function was evaluated by indirect measurement of SNRT by pacing for 30 seconds at cycle lengths of 200, 150, and 100 ms and measuring the duration of the return cycle.

WebCorrected SNRT was not different between groups despite the larger noncorrected SNRT obtained in trained animals. Thus training depresses sinus chronotropism, A-V nodal conduction, and increases ventricular refractoriness by intrinsic mechanisms, which do not involve changes in myocardial mass and/or coronary flow.
