With control of body temperature within +/- 0.2 degree C of the set point, heart rate is stabilized and, in turn, repetition time (TR) during cardiac-gated studies is less variable.
At each sampling time point, heart rate was recorded from an electrocardiograph (Quinton Q750, Seattle, WA, USA).
At similar time points, heart rate and systemic and pulmonary pressures were registered.
There were no significant differences between Groups, Assessments, or Interaction (Groups × Assessments) for the four VAS end-points, heart rate variability, or breath rate (p > 0.05, for all comparisons).
At the 8 h time point, the heart rate change from baseline remained near maximum, but at 24 h, the mean increase in heart rate had dropped to near baseline.
This score included the H-FABP bedside-test (a positive result was assigned 1.5 points), tachycardia (heart rate above 100 beats/min on admission assigned 2 points), and syncope (presence of syncope assigned 1.5 points).
"Seeing at what points my heart rate peaks and things like that will make it easier for me to tailor my own workouts when I'm not with the team," he said.
Secondary end points include heart rate variability, diurnal blood pressure, glucagon suppression and inflammatory response (urine, blood and adipose tissue).
The clinical parameters evaluated at the pre-determined time points included heart rate (HR), respiratory rate (RR), rectal temperature (RT), capillary refill time (CRT) and systolic blood pressure (SBP).
In group A (n = 10), at time point 3 compared with time point 2, the heart rate significantly decreased (from 75±10to66o 66 ± 7 beats/min).
Impress your pals Seals can dive as deep as 200 metres for 30 minutes at a time - at which point their heart rates slow from 120 beats a minute to just four or five.
