It has been suggested that we state "Prolonged QT" whenever the QTc exceeds 460 milliseconds (Bazett correction). Although 460 milliseconds is above the 98th percentile of QTc for most age groups of normal subjects, large numbers of ECGs have QTc more than 460 milliseconds for which the ...
What conditions or situations cause prolonged QT intervals in the electrocardiogram besides the use of antidepressants? If there is a need for an antiarrhythmic in a patient on an antidepressant, which antiarrhythmics are less likely to cause further prolongation of the QT interval?. ...
(R–R cycle length), so heart rate correction is required in the analysis of repolarization duration. Various heart rate cor- rection formulae have been developed in order to determine whether the QTinterval is prolonged in comparison to its pre- dicted value at a reference heart rate of 60...
Vascular eye-based measures are considered a proxy for the status of the cerebrovascular system,73,74 which is assumed to play, among other factors, a vital role in the positive relationship between physical activity and fitness and measures of cognitive performance.13,34,36,75 Various approaches...
CHAPTER IX. WHAT IS NOBLE? 257. EVERY elevation of the type "man," has hitherto been the work of an aristocratic society and so it will always be—a society believing in a long scale of gradations of rank and differences of worth among human beings, and requiring slavery in some form ...
Libya was clearly the template for intervention suggestions, but such moves died in the security council or were only tepidly considered by NATO. Specifically: “too much had been set in motion for the Assad regime to calmly hold on to power, as what began as a protest movement has become ...
14 A notable feature of these newer V-agents is that they are more persistent—i.e., they do not wash away or degrade easily and can remain active on surfaces for weeks or even months. In contrast, G-agents are considered non-persistent. While V-agents primarily work by contact, they ...
Lebanon and Jordan are the countries most immediately affected by Syria's conflict, with M&A in the two countries having virtually dried up. In Iraq, however, M&A is expected to continue, predominantly in the energy sector. It is Iraq's northern region, Kurdistan, that is considered to have...
(2021) found 18 QTLs and 7 QTNs were associated with the increasing planting density, suggesting genetic variations for the PH trait at various densities. But the QTLs and QTNs for PH that were considered stable were also repeatedly detected by multiple statistical methods, densities, or environm...
In the past, asthma was considered mainly as a childhood disease. However, asthma is an important cause of morbidity and mortality in the elderly nowadays. In addition, the burden of asthma is more significant in the elderly than in their younger counterparts, particularly with regard to mortalit...
