Mean RVSP over the first ten stable heartbeats was recorded.
Shear wave velocity estimates ranged from 0.82 to 2.65 m/s and were stable across multiple heartbeats for the same interrogation region, with coefficients of variation less than 19% for all matched acquisitions.
In this method, a heartbeat is delineated into stable and flexible segments which are resampled at two different rates and then concatenated again.
However, this paradigm is often difficult in live animal due to animal movement (breathing and heartbeat): z-stack recording requires a stable tissue volume to avoid any distortion for the duration of the acquisition which can be several seconds.
To keep their blood pressure stable, phocids have an elastic aorta that dissipates some energy of each heartbeat.
Periodicity and instability of the heartbeat sequence may also affect pulse-counting accuracy Heartbeat rhythm may not be constant and stable even in healthy people; fluctuations always exist.
His position was stable for now, but with Blackhawk in the process of buying the company out, that could change in a heartbeat.
