We evaluated atrioventricular conduction time (PR), heart rate (HR), and QT interval patterns defining the range of normality of these electrocardiographic parameters. The PR interval ranged from 154± 10 ms (mean±SD) for HR¤60 to 102±12 ms for HR 120 (range 85180). The absolute mean ...

An apparently normal ECG is defined by the following [30]: 1) heart rate between 55 and 100 bpm; 2) presence of P waves in all leads, with normal morphology; 3) presence of a QRS complex following each P wave; 4) PR interval between 0.12 to 0.20 seconds; 5) QRS duration ≤ 0.12...
HR - Heart rate; bpm - beats per minute; ms - milliseconds; PRI – PR interval; QTI – QT interval; QTIc - QT interval corrected. Women showed higher median heart rate values, as well as the QT interval corrected by the Hodges, Bazzet, Fridericia and Framinghan formula, while men disp...
(Zeiss, Oberkochen, Germany) was used to acquire z-stacks with a 63× objective (numerical aperture of 1.4) in Airyscan mode. An interval of 0.19 μm was used between images within each stack (~ 50 slices), while focus stacking was performed using the Zen 3.1 software (Blue edition, ...
