Target heart rate (THR) has always been based on a unisex formula, but now researchers say that works out to be too high for women. The new calculations are in this chart. Why the big range? If you're a newcomer to exercise (or a return visitor), aim for the lowest part of the ...
Exercise should be a part of any healthy individual's fitness plan. There are certain characteristics of exercise that can make workouts more effective for increasing fitness or for maintaining fitness. These characteristics can be summarized in something called the FITT formula. ...

Summary We studied the relationship between QT interval and RR interval when the heart rate was changed by atrial pacing, atropine, isoproterenol, and exercise in nine healthy adult males. The following results were obtained: (1) QT shortening with an increase in heart rate was minimal in atrial...
Fetal gestational age is an important consideration, as the likelihood of a nonreactive fetal heart rate test is greater at preterm GAs. Given these considerations, most centers do not initiate these screening tests until 32 to 34 weeks unless there are indications for earlier testing (e.g., ...

While there is substantial familiarity with the Bazett (QTcB) formula (QT/ (RR) 1/2), the Fridericia (QTcF) formula (QT/ (RR)1/3) is preferred in the cancer population as it is often more accurate at heart rate extremes [5]. Accordingly, the Fridericia formula is currently the ...
