We obtained heart rate from the transmitter signals using methods described elsewhere [19].
We divided flights into initial ascent and cruise phases that we analyzed separately; data for a final descent phase were insufficient for analysis and we were unable to obtain heart rate during the initial ascent phase for one of the 15 thrushes.
However, the obtained heart rate values from the two instruments correlated much better.
HRRs are based upon where most Medicare recipients living in contiguous zip codes obtain heart surgery and neurosurgery [ 11].
Therefore, we first obtained heart rate from ECGs and then acquired HRV and the power spectrum of HRV.
The difficulty to obtain heart tissues from healthy and HCM human hearts is the major obstacle for studying HCM using human cells.
To obtain heart cells of a more mature phenotype, the generation of three-dimensional (3D) so-called engineered heart tissue (EHT) could be an option.
These measurements were then used to obtain heart rate corrected Q-T interval durations using Bazett's [ 2] formula: Q-Tc = Q-T/ R-R)½.
Blood pressure was measured in triplicate and the last two measurements were averaged to obtain heart rate and systolic and diastolic blood pressure.
To obtain heart recovery rate, the amount of flies that restores their heart beat at 4 minutes after being in a state of cardiac-arrested at 0 minute was measured [ 10].
