Summary
| Description |
English: The flow velocity, pressure, and instantaneous microvascular resistance were calculated over the wave-free period and during that of the complete cardiac cycle. Flow velocity is higher, and pressure is lower over the wave-free period. This results in lower microvascular resistance during the wave-free period in comparison to the complete cardiac cycle. Values are expressed as median+/-interquartile range.
