2021年2月4日 · The PR interval is the time from the onset of the P wave to the start of the QRS complex. It reflects conduction through the AV node. The normal PR interval is between 120 – …

2019年11月18日 · La durée normale entre le début de l’onde P et le complexe QRS (assimilé à l’onde R ou Q) est comprise entre 120 et 200 ms. Cette durée (PR) doit être interprété en …

In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS …

双向P波是指波的描迹线在参考水平线两侧各有一个转折点，双向P 波的起始转折在参考水平线以上称正负（＋－）双向，起始转折在参考水平线以下称负正（－＋）双向，如果正向P波终末 …

The PR interval is assessed in order to determine whether impulse conduction from the atria to the ventricles is normal. The flat line between the end of the P-wave and the onset of the QRS …

The flat line between the end of the P-wave and the onset of the QRS complex is called the PR segment and it reflects the slow impulse conduction through the atrioventricular node. The PR …

2021年2月4日 · PR segment elevation or depression in patients with myocardial infarction indicates concomitant atrial ischaemia or infarction. This finding has been associated with poor …

2025年2月2日 · The most important findings in Wolff-Parkinson-White syndrome are a short PR interval, the presence of the delta wave and wide QRS complex. In ectopic atrial pacemaker or …

2 天之前 · Understanding a Short PR Interval on an ECG: Causes and Clinical Implications. Electrocardiography (ECG) is a critical tool in cardiovascular medicine, providing valuable …

The PR segment is the flat line between the end of the P-wave and the start of the QRS complex. The PR segment reflects the time delay between atrial and ventricular activation. The PR …
