2024年10月8日 · Sinus bradycardia = sinus rhythm with resting heart rate < 60 bpm in adults, or below the normal range for age in children; Sinus arrhythmia = sinus rhythm with a beat-to-beat variation in the P-P interval (the time between successive P …

A rhythm is defined as three consecutive heartbeats with identical waveforms on the ECG. The similarity of the waveforms indicates that the origin of the impulse is the same. 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 ...

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]

2023年10月31日 · 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,...

2025年1月29日 · On an Electrocardiogram (ECG), the normal sinus rhythm (NSR) appears as a consistent and orderly pattern, indicating healthy heart function. NSR, also known as the heartbeat, is driven by electrical signals from the Sinus Node. These signals travel through the heart’s valves and cause contraction and expansion to facilitate blood flow.

2025年2月2日 · Sinus rhythm has a heart rate higher than 60 bpm and lower than 100 bpm. If heart rate is lower than 60 bmp it is called sinus bradycardia, if heart rate is higher than 100 bpm it is called sinus tachycardia. Sinus rhythm: Minimum R-R interval (100 bpm = 3 squares) and maximum R-R interval (60 bpm = 5 squares).

2021年11月8日 · A normal sinus rhythm refers to both a normal heart rate and rhythm. Normal heart rates are from 60 to 100 beats per minute. The shape of the electrocardiogram (EKG) tracing will exhibit certain key attributes to be considered normal, as discussed below.

Learn about sinus rhythm in ECGs, including the P wave, its relation to the EKG curve, and frequency analysis for accurate cardiac assessment.

Sinus rhythm is the name given to the normal rhythm of the heart where electrical stimuli are initiated in the SA node, and are then conducted through the AV node and bundle of His, bundle branches and Purkinje fibres. Depolarisation and repolarisation of the atria and ventricles show up as 3 distinct waves on ECG.

Sinus rhythm is the normal, regular rhythm of the heart, set by the natural pacemaker known as the sinoatrial (SA) or sinus node. When interpreting an ECG, healthcare professionals look for specific criteria to confirm that the heart is in sinus rhythm:
