Dec 19, 2025 · What Is a Normal Sinus Rhythm? Normal sinus rhythm means the heartbeats are regular and between 60 and 100 beats per minute. Sinus rhythm is controlled by the sinus node, which …

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 …

Jun 16, 2025 · Is your heart beating normally? Learn how to identify a normal sinus rhythm on an ECG. Discover key features, common patterns, and what it all means

Oct 8, 2024 · In normal sinus rhythm, pacemaking impulses arise from the SA node and are transmitted to the ventricles via the AV-node and His-Purkinje system

Nov 18, 2024 · 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 …

Aug 18, 2025 · Beyond the rate, a healthy sinus rhythm is notably regular and consistent, with minimal variation between successive beats. This regularity reflects the precise timing of electrical impulses …

Nov 8, 2021 · With normal sinus rhythms, the heart beat's electrical impulse originates in the sinoatrial node (SA). The P waves are upright and appear before each QRS and have the same shape.

The sinoatrial (SA) node is the heart’s pacemaker under normal circumstances and the rhythm is referred to as sinus rhythm. Hence, sinus rhythm is the normal rhythm of the heart.

Oct 2, 2025 · The normal sinus rhythm is the rhythm and rate of impulses generated by certain muscle cells as a signal to the upper heart chambers (atria) to contract. The heart contains a cluster of …

Mar 17, 2025 · Sinus rhythm is the heart rhythm which arises from the sinusnode. In most cases these electrical stimulus is transmitted throughout the conduction system and depolarizes the atria and the …
