Oct 31, 2023 · Sinus rhythm refers to the rhythm of your heartbeat, determined by the sinus node of your heart. The sinus node creates an electrical pulse that travels through your heart...
A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. It is necessary, but not sufficient, for normal electrical activity within the heart. On the electrocardiogram (ECG), a sinus rhythm is characterised by the presence of P waves that are normal in morphology.
Mar 21, 2022 · What is sinus arrhythmia? Sinus arrhythmia is a kind of arrhythmia (abnormal heart rhythm). For the most common type of sinus arrhythmia, the time between heartbeats can be slightly shorter or longer depending on whether you’re breathing in or out. Your heart rate increases when you breathe in and slows down when you breathe out.
Aug 10, 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.
5 days ago · Sinus rhythm is the pattern of your heartbeat. Heart rate is the number of times the heart beats per minute. A normal sinus rhythm is associated with a heart rate between 60 and 100 beats per minute. What Is a Normal Sinus Rhythm?
Mar 11, 2021 · Mar 11, 2021. Home ECG Library. ECG Library Homepage. 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.
