If the rhythm is sinus rhythm (i.e. under normal circumstances) the P-wave vector is directed downwards and to the left in the frontal plane and this yields a positive P-wave in lead II (Figure 2, right-hand side). The P-wave is always positive in lead II during sinus rhythm.

8 Οκτ 2024 · Overview of normal sinus rhythm (NSR) The default heart rhythm; Pacemaking impulses arise from the sino-atrial node and are transmitted to the ventricles via the AV-node and His-Purkinje system; This results in a regular, narrow-complex heart rhythm at 60-100 bpm
Sinus rhythm (which is the normal rhythm) has the following characteristics: (1) heart rate 50–100 beats per minute; (2) P-wave precedes every QRS complex; (3) the P-wave is positive in lead II and (4) the PR interval is constant.
Definition (criteria) for sinus rhythm. Regular rhythm with ventricular rate between 50 and 100 beats/min. P-wave with constant morphology preceding every QRS complex. The P-wave is positive in lead II. Figure 1 (below) shows normal sinus rhythm at paper speed 25 mm/s.
10 Νοε 2022 · This article is a guide for interpreting abnormal Normal Sinus Rhythm EKGs, including qualifying criteria and a sample EKG rhythnm strip. Normal sinus rhythm is indicated by a heart rate in the normal range of 60-100 beats per minute with a steady rate, aside from variations due to respiration.
A regular heart rhythm originating from the sinoatrial node, characterized by a rate of 60-100 beats per minute, upright P waves before each QRS complex, and a consistent PR interval.
An electrocardiogram - an ECG - or the dutch and german version of the word - elektrokardiogram or EKG, is a tool used to visualize “gram” the electricity “electro” that flows through the heart “cardio”.
