2. 2. The average duration of the QRS complex in 100 normal adults was 0.0777 second. Fifty of the patients were males with an average duration of the QRS time interval of 0.0833 second, and 50 were females with a shorter time interval of 0.0722 second. The average duration of the QRS ...
Objective To explore the relativity of normal QRS complex duration(QRSd) and heart failure. Methods155 patients with chronic heart failure( HF) were admitted,and 40 persons without heart failure were choosed as controls. According to the measurements of QRSd,patients of HF were classified into ...
LV diastolic dimension ( L M ) was measured at the onset of the QRS complex of the EKG in a sector of the LV containing the mitral valve echoes. LA dimension (LAD) on echo was obtained at the period of maximal anterior excursion of the arotic root in an ultrasound plane containing ...
The QT interval extends from the beginning of the QRS complex to the end of the T wave. Since the report of Jervell and Lange-Nielsen in 1957, it has been difficult to determine whether to measure a QT or a QU interval. U waves are more prominent in the left chest leads and less pr...

QRS间期正常1. Objective:The aim of this study was to assess the prevalence of systolic dyssynchrony of the LV walls in patients of HF with a normal QRS duration by Doppler tissue imaging(DTI). 目的:应用多普勒组织显像(DTI)评估严重心衰而QRS间期正常的患者左室收缩不同步的发生率。
An earlier study of 1555 normal 12 lead electrocardiograms has shown that the mean QRS duration in men is 8 ms longer than in women. To establish the sex related normal limits of the signal averaged electrocardiogram. PEOPLE: 195 people (160 men and 35 women aged 40 to 69) with normal cl...

Rate-dependent effects of intravenous lidocaine, procainamide and amiodarone on intraventricular conduction In this study, the duration of the QRS complex during ventricular pacing was used as an index of intraventricular conduction to quantitate the rate-depende...

Note the remarkably fast heart rate (260 bpm) and narrow QRS complexes without discernible P waves. It often can be difficult to interpret the ECG in this setting, because the normal QRS complex width is shorter in infants and young children. View article Left-to-Right Shunt Lesions Myung K...
