A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. [1] It is necessary, but not sufficient, for normal electrical activity within the heart. [2] On the electrocardiogram (ECG), a sinus rhythm is characterised by the presence of P waves that are normal in morphology. [2]
31 Οκτ 2023 · Your sinus rhythm is the pattern of electrical pulses from your sinus node, your heart’s pacemaker. It’s not uncommon for sinus rhythm to be too slow or too fast, but symptoms that...
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 is the normal rhythm of the heart and no treatment is relevant. Learn the definition, physiology, criteria for sinus rhythm, with emphasis on ECG interpretation. Arrhythmias from the sinoatrial node are also discussed.
10 Αυγ 2022 · Normal sinus rhythm (NSR) is the rhythm that originates from the sinus node and describes the characteristic rhythm of the healthy human heart. The rate in NSR is generally regular but will vary depending on autonomic inputs into the sinus node.
A cardiac rhythm strip only indicates normal sinus rhythm (NSR) when all of the following criteria are fulfilled: The rhythm is regular with consistent R-R intervals. Atrial and ventricular rates between 60 – 100 beats per minute (bpm) Each QRS complex is preceded by a distinct P wave.
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.
