英文原文: The importance of defining QRSduration by sex, particularly in left bundle branchblock (LBBB), has been advocated by Strauss et al,as women have been reported to show response toCRT with QRS durations starting at 130 ms, whereasmen do ...
QRS duration immediately postexercise shortened by 7.1 +/- 4.3 ms (range 2-11.5 ms), which was not significantly different from the results obtained with the digital ECG. We conclude that decreased QRS duration is a physiological response to moderate treadmill exercise in healthy men, reflecting ...
3. 3. Total QRS duration in XYZ leads was measured in 115 men, aged 20 to 50 years. The range of values was 0.0801 second to 0.1309 second, the mean 0.1010 second, the standard deviation 0.010 second. 4. 4. It is suggested that 0.12 second be the "upper normal limit" of QRS ...
Comparison of QRS Duration and Associated Cardiovascular Events in American Indian Men versus Women (The Strong Heart Study)Resting electrocardiographic QRS duration is associated with sudden cardiac death and death from coronary heart disease in the general population. However, its relation to ...
In some series,7,9 however, the QRS duration was less than 0.10 second in almost one third of the cases, presumably due to fusion between preexcited and normally conducted complexes. The sum of the PR and QRS intervals usually remains within the normal range. A normal “septal” q wave ...
myocardial volume alone. In proportional terms, adult heart sizes are less variable compared to the QRS duration11and while heart size reasonably correlates with body size12, the QRS duration does not9. This all potentially makes the broad range of the normal QRS complex durations somewhat ...
Duration of QRS Complex in Resting Electrocardiogram Is a Predictor of Sudden Cardiac Death in Men Background—Previous studies indicate that increased QRS duration in ECG is related to the risk of all-cause death. However, the association of QRS duratio... S Kurl,Timo H Mkikallio,P Rauta...
