By now, his mail was dominated by glossy Chinese flyers for ginseng products — Prince Gold Heart Formula, Pure American Ginseng Powder — all of them coming from a company called Prince of Peace Enterprises, in Wausau, Wisconsin.
The objective of this paper was to determine how age-predicted heart rate formulas can be used with fibromyalgia syndrome populations as well as to find out which mathematical models are more accurate to control exercise intensity.

For QTc interval calculation, in addition to Bazett's formula, linear and parabolic heart rate correction formulas with two separate α values were used.
To compare 4 heart rate correction formulas for calculation of the rate corrected QT (QTc) interval among infants and young children.
Significant difference in QTc between waking and NREM sleep obtained in our study by certain heart rate correction formulas seems to have no clinical importance as the mean values of the parameter remained in physiological range.
Malik and coauthors [ 10] have converted several QT/RR regression models (linear, hyperbolic, parabolic, logarithmic, shifted logarithmic, and exponential models) to generic heart rate correction formulas to provide QTc interval values that are independent of the corresponding RR interval values.
Cardiac output (CO) was calculated with special program of echocardiography using [(end diastolic volume − end systolic volume)/1000] × heart rate] formula for each infant.
Moreover, the use of ad hoc heart rate correction formulae (such as Bazett's) may bias the result (Aytemir et al, 1999).
The published non-clinical QT data were included irrespective of the animal model conditions (anaesthesia, restrained or unrestrained, conscious), the drug treatment protocol, the ECG methodology used to monitor the QT interval or the heart rate correction formula.
