简要总结
- The primary objective of this study is to assess the effect of an energy drink on ventricular repolarization as measured by the interval between the cardiac Q wave and the cardiac T wave (QT interval)obtained from the body surface ECG.
- The secondary objective is to assess the effects of an energy drink on heart rate and blood pressure (hemodynamic effects).
To place the observed changes in context, comparison will be made to a commonly consumed drink, coffee: Starbuck's K-cup Breakfast Blend.
详细描述
This study will assess cardiac repolarization before and after three conditions each of which will involve the subject drinking beverages of varying caffeine content.

结局指标
主要结局
QT interval will be measured in msec
时间窗: 19 hrs
The investigators will be measuring cardiac QT interval before (baseline) and for 5 hours post beverage consumption. The measurements will be made in msec.
次要结局
- Heart rate will be measured as beats per minute.(19 hrs)
- Blood Pressure will be measured in the brachial artery as mmHG(19 hrs)
