窦性心律(Sinus rhythm)是指心脏的起搏点位于窦房结(心脏的自主起搏点)并以正常的频率发放冲动,从而使心率保持在正常范围内。窦性心律是一种正常的心律,通常被认为是心电图报告中最理想的心律。在心电图报告中,窦性心律通常表示为"Sinus rhythm"或"S.R.",它具有以下特征:1、P波:窦性心律的P波形态...

Ventricular tachycardia (VT) substrate in left ventricular (LV) nonischemic cardiomyopathy (NICM) consists of fibrosis with surviving myocardium.#The purpose of this study was to determine whether, in patients with LV NICM and sustained VT, reduced QRS amplitude and QRSf during sinus rhythm can ...
In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect? ECG: An ECG, or electrocardiogram, is an electrical readout of the heart which measures the electrical output of all heart chambers during cardiac cycles. T...
Rhythm of the coronary sinus. 冠状窦性节律(coronary sinus rhythm)与逆行P波在QRS波前之结性节律所不同者,仅P-R超过0.12秒.按Scherf氏的臆断,其节奏点系位于右房冠状窦附近,故称此种异位节律为冠状窦性节律;但以后Scherf氏也承认此节律不可能与起源于房室结上部的结性节律区别.Langend... L Bugaro,L ...
Review of the Holter monitor data revealed a preictal rhythm consisting of sinus tachycardia rapidly deteriorating to sinus bradycardia with a 19-second period of asystole during the event. Arrhythmias in the epilepsy monitoring unit: watching for sudden unexpected death in epilepsy Our study was desi...
(Fig. 38-6,D). ECG analysis shows P waves at one rate and wide QRS complexes at a separate rate. As with other forms of heart block, finding and eliminating the causative agent are curative. If hemodynamically stable, observation is often suitable. However, if the rhythm deteriorates or ...
Twenty-six patients demonstrated a type A and seven a type B WPW pattern during periods of sinus rhythm. Male patients predominated. The average age was 38.5 years among patients with a type A pattern compared with 25.3 years among those with a type B pattern. The shortest R-R cycle ...
Unresolved tachycardia in a 14 year old with acute lymphoblastic leukemia patient Analysis of the ECG changes revealed that 22 subjects developed sinus tachycardia (36.67), 13 subjects transient ischemic changes (21.67) and 1 subject each developed occasional atrial ectopics and junctional rhythm (1.67...
