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 ...

HR - Heart rate; bpm - beats per minute; PRI - PR interval; QTI - QT interval; QTIc - QT interval corrected; Sokolow-Lyon index (SV1 or SV2 + RV5 or V6), Cornell Index (S in V3 + R in aVL). ⁎ P-values obtained by the Mann-Whitney test. Table 3. Normal ECG ...
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...

During the second stage of labor, perineal massage with lubricants and warm compresses may soften and stretch the perineum and thus reduce the rate of third- and fourth-degree perineal tears (6). These techniques are widely used by midwives and birth attendants. ...
Her baseline 12-lead electrocardiogram showed normal sinus rhythm with normal PR interval and preexisting right bundle branch block with QRS duration of 138 milliseconds. Profound Sinoatrial Arrest Associated with Ibrutinib (14) identified normal sinus rhythm in 76%, sinus tachycardia in 9%, sinus br...
An ECG reading contains a P wave, QRS copmlex, and T wave with intervals that include the PR interval and QT interval. The P wave represents atrial...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a ques...
