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 ...
Duration of QRS Complex 喜欢 0 阅读量: 12 作者:P Fazzini,F Marchi 摘要: The paper considers automatic, specification-based detection of failures (differences between observed and specified behavior) in external behavior of software systems. The external behavior is recorded in traces, which are ...
Fill in the blanks: In an ECG under normal conditions, the duration of the QRS complex is less than ___ second, or ___ small squares. The Ventricles of the Heart: The ventricles refer to the bottom two chambers of the heart. The right ...
The clinical background, QRS complexes before pacing, and the echocardiographic findings were assessed. Males (P < 0.05), those with H-V block (P< 0.05) and a wider QRS complex of conducted and escape beats (both P < 0.01) were dominant in group I. The incidence of underlying heart ...
Left-sided intraventricular conduction delay is associated with more advanced myocardial disease, worse left ventricular (LV) function, poorer prognosis, and a higher all-cause mortality rate compared with narrow QRS complex. It also predisposes heart failure patients to an increased risk of ventricular...

This paper evaluates the QRS complex duration (QRSd) as a parameter for measuring heartbeat-alignment, using both Derivative Dynamic Time Warping (DDTW) and Piecewise Linear Approximation (PLA). Results show that using those algorithms it is possible to reach acceptable SNR, significant QRSd ...
last-to-depolarize ventricular chamber of the heart; and a control circuit coupled to the timing circuit and the sensing circuit to adjust the length of the at least one time interval based on the measured duration of the QRS complex of the last-to-depolarize ventricular chamber of the heart...
