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

Schematic representation of normal sinus rhythm showing standard wave, segments, and intervals. A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. [1]
5 Μαΐ 2022 · When an EKG tracing meets these criteria —sinus-originating, fixed P-QRS-T repeating pattern, and HR between 60 and 99— it can be called Normal Sinus Rhythm. Normal Sinus Rhythm means: An EKG rhythm starting at the SA Node with a rate between 60 and 99 which follows the expected electrical path through the heart.
Normal sinus rhythm is when the heart's electrical activity is regular and originates in the heart's natural pacemaker, the sinoatrial (SA) node. The (SA) node is located in the right atrium and regularly fires electrical impulses.
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.
The diagnosis of the normal electrocardiogram is made by excluding any recognised abnormality. It's description is therefore quite lengthy. normal sinus rhythm. each P wave is followed by a QRS. P waves normal for the subject. P wave rate 60 - 100 bpm with <10% variation. rate <60 = sinus bradycardia. rate >100 = sinus tachycardia.
31 Οκτ 2023 · In adults, normal sinus rhythm usually accompanies a heart rate of 60 to 100 bpm. However, it’s possible for sinus rhythm to be faster or slower than this and still be considered normal.
