WebNormally, the QRS interval is 0.07 to 0.10 second. An interval of 0.10 to 0.11 second is considered incomplete bundle branch block or a nonspecific intraventricular conduction delay, depending on QRS morphology. An interval ≥ 0.12 second is considered complete bundle branch block or an intraventricular conduction delay. WebThe PR interval reflects whether impulse conduction from the atria to the ventricles is normal. The PR interval must not be shorter than 120 msec or longer than 220 msec. …

WebR-wave peak time (Figure 9) is the interval from the beginning of the QRS-complex to the apex of the R-wave. This interval reflects the time elapsed for the depolarization to spread from the endocardium to the epicardium. R-wave peak time is prolonged in hypertrophy and conduction disturbances. Normal values for R-wave peak time follow: Web7 de jul. de 2024 · First-degree atrioventricular (AV) block is a condition of abnormally slow conduction through the AV node. It is defined by ECG changes that include a PR interval of greater than 0.20 without disruption of atrial to ventricular conduction. This condition is generally asymptomatic and discovered only on routine ECG.
