In an analysis of 44896 ECGs representing all adult non鈥搗entricular-paced ECGs in a major hospital ECG database over the course of 1 calendar year, the computerized interpretation program stated "Prolonged QT" on 9.8% of the ECGs. However, 36.2% of all ECGs had a QTc more than 460 ...
The ECG interpretative statement "Prol onged QT" means different things to different people. It can be taken as a purely descriptive statement referring to the QT interval beyond a certain threshold. Alternatively, it could be taken to refer to a disease state (eg, congenital long QT syndrome...
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?. ...
14 Although it is standard practice to measure the QT interval from the beginning of the QRS complex to the end of the T wave, the actual methods of measurement have not been standardized. Because the QT interval is prolonged at slower heart rates and shortened at faster heart rates, many ...

On the basis of the original plan of “four vertical and four horizontal” main structure, the existing railways are fully utilized to form a high-speed railway network with “eight vertical and eight __...
[155]. The sometimes associated reduction in serum potassium and electrocardiographic changes in QT interval may be of concern in cardiac patients, although rarely significant. Long-acting β-adrenergic agonists can be used in association with ICS to improve asthma control in more than mild severity...
HIIE = high-intensity interval exercise; HRmax = maximal heart rate; HRR = heart rate reserve; LT = lactate threshold; LUT = mid-luteal; MET = metabolic equivalent of task; MICE = moderate-intensity continuous exercise; mph = miles per hour; MVPA = moderate...

HVE colleges focus on talent cultivation, which does not mean they will never engage in academic research. The key is to decide and evaluate the research types for HVE colleges. First, a survey was conducted on the current status and practical needs of HVE colleges globally and especially in ...
