These findings support the theory that patients with low parasympathetic activity (low short-term RR interval variability) have an increased risk for sudden death independent of other risk factors. 展开 关键词: AUTONOMIC NERVOUS SYSTEM HEART RATE RISK FACTORS ...

The risk of sudden death from myocardial infarction was increased in subjects with a resting heart rate that was more than 75 beats per minute (relative risk, 3.92; 95 percent confidence interval, 1.91 to 8.00); in subjects with an increase in heart rate during exercise that was less than ...
Background— In a recent cohort study, prolongation of the corrected QT interval (QTc) was associated with an independent increased risk of sudden cardiac ... SS Chugh,K Reinier,T Singh,... - 《Circulation》 被引量: 394发表: 2009年 Risk of Serious Cardiovascular Problems with Medications for...
QTD and heart rate each were significantly ( P <.01) and independently associated with increased risk for SUCD. Only primary prevention can reduce the risk for SUCD. Hence, this relationship between QTD and heart rate and SUCD emphasizes the importance of longitudinal noninvasive QT measurements...

Increased mortality but not increased rate of sudden cardiac death is associated with low haemoglobin levels in chronic heart failure patients 来自 ResearchGate 喜欢 0 阅读量: 11 作者:T Karhausen,W Doehner,SD Anker,D Wietholt 摘要: The SPRINTT project has two major objectives. First, it will...
We have tested the hypothesis that autonomic instability, reflected in increased variability of heart rate and respiratory frequency, characterized high risk babies who died of sudden infant death syndrome. Using computer-based methods, we compared the power spectra of instantaneous heart rate and ...

These abnormalities increased with advancing stages of the syndrome. These findings suggest a possible role of cardiac dysfunction in the sudden death associated with RETT syndrome.关键词: Rett syndrome Heart rate variability Sudden death QTc
