Sinus rhythm is the normal rhythm of the heart with a constant P-wave preceding every QRS complex. Learn how to identify sinus rhythm on the ECG and its clinical implications with this article.
Sinus rhythm is a cardiac rhythm where depolarisation starts at the sinus node. Normal sinus rhythm (NSR) is a specific type of sinus rhythm with normal ECG measurements, but the term is sometimes discouraged.
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.
7 Ιουν 2024 · What Is a Normal Sinus Rhythm? Normal sinus rhythm (NSR) is another name for a normal heart rhythm. The heartbeat is controlled by electrical signals that are transmitted to the four chambers of the heart, causing them to contract and relax in sequence to pump blood in and out of the heart.
