Oct 31, 2023 · Normal sinus rhythm is defined as the rhythm of a healthy heart. It means the electrical pulse from your sinus node is being properly transmitted throughout the heart muscle. In adults,...

Jan 14, 2024 · What Is a Normal Sinus Rhythm? Normal sinus rhythm is when your heart beats in a regular, organized way. Your body has a built-in pacemaker called the sinoatrial (SA) node, or sinus node.

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]

Jun 7, 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.

Oct 8, 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

Mar 20, 2025 · Sinus rhythm is the heart’s natural beat, and arrhythmias occur when a disruption in the heart’s natural beat occurs. For example, a normal sinus rhythm shows a steady, predictable pattern on an ECG. This indicates the heart is beating normally.

Nov 8, 2021 · What is a Sinus Rhythm? This page provides an introduction to sinus rhythms and links to our EKG interpretation courses and drills. A normal sinus rhythm refers to both a normal heart rate and rhythm. Normal heart rates are from 60 to 100 beats per minute.

At its core, the heart functions through electrical impulses that dictate its rhythm. These impulses originate from specialized cells within the heart known as pacemaker cells. The primary pacemaker is located in the sinoatrial (SA) node, situated in the right atrium.

Jul 7, 2020 · What is a sinus rhythm? The sinus node is one of the natural pacemakers of the heart, creating an electrical pulse that travels through the muscles in the heart, causing it to beat. A sinus rhythm is any cardiac rhythm where depolarization of the …

Learn the definition, physiology, criteria for sinus rhythm, with emphasis on ECG interpretation. Arrhythmias from the sinoatrial node are also discussed.
