2022年5月5日 · Normal Sinus Rhythm (NSR) is the expected rhythm on an EKG in patients without pathophysiology. It represents the normal electrical cycle of the heart, which was discovered once a tool capable of detecting it was invented: the electrocardiogram (EKG/ECG).

2024年10月8日 · 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

Characteristics and Criteria for Normal Sinus Rhythm. The p wave represents the atrial rhythm and rate. Therefore, the atrial rhythm should be regular and rate 60-100 bpm. PR interval should measure 0.12-0.20 seconds….anything greater than 0.20 seconds, think HEART BLOCK.

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.

2025年3月17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).

扩展卡尔曼滤波（Extended Kalman Filter，EKF）通过局部线性来解决非线性的问题。 将非线性的预测方程和观测方程进行求导，以切线代替的方式来线性化。

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

2006年5月1日 · An ECG signal is considered as NSR as long as all the P, Q, R, S, T waves are present in the waveform and the heart rate is normal, i.e. between 60 and 80 cycles per minute for an adult. Hence, the NSR class covers a broad range of ECG signals.

2019年3月23日 · 普通的扩展卡尔曼滤波（ekf），通过对动态方程的线性化，来估计状态与状态的协方差。 比如有一个系统定义为 其中 是系统状态， 是输入， 是系统噪声。

2021年11月8日 · Normal sinus rhythm is indicated by a heart rate in the normal range of 60-100 beats per minute with a steady rate, aside from variations due to respiration. P waves should be positive and within a normal amplitude (< 2.5mm at lead II and III). This article is a guide for the ECG interpretation of Normal Sinus Rhythm, including a sample ECG strip.
