WebA 28-year-old man with a 3-year history of frequent attacks of tachycardia was admitted to our hospital because of palpitations. The ECG revealed a sinus rhythm of approximately 60 beats/min, a PR interval of 0.10 s, and a QRS duration of 0.14 s (with a delta wave), with rS pattern in lead V 1, suggestive of WPW syndrome type B . Web15 de fev. de 2024 · Absence of P Waves. A lack of visible P waves preceding QRS complexes suggests a lack of sinus beats; this may occur with sinus dysfunction or in the presence of fibrillation or flutter waves. The P wave may also be hidden within the QRS complex. Atria. Ventricles.

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 complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration. The PR interval is sometimes termed the PQ interval. WebUniversity of Nottingham
