• Added a new single-beat detection method ‘Sinusoidal pressure fit’.
• Added single-beat ESPVR (end-systolic pressure-volume relationship) into the hemodynamics table.
• Added single-beat Piso (max pressure of an isovolumic beat) into the hemodynamics table.
• Added a new ‘Loop tangent fit’ method for calculating ESPVR and the End Systolic points from multiple beats during occlusions.

Note: the Sinusoidal pressure fit’ and ‘Loop tangent fit’ methods are especially useful for right ventricle measurements and other situations where the PV loop has a ‘triangular’ shape.

Bug fixes:

• Fixed potential crash when Stroke Volume mode set to ‘Stable EDV - ESV’.
• Fixed incorrect macro descriptions for ‘SetESPVRegressionType’ and ‘SetEDPVRegressionType’.

Known issues:

• The ES Pressure and ES Volume Channel Calculations do not show the ES points derived from the tangent fit (unlike the Hemodynamics Table). Instead they show either the max (P/V) ES points or the sine fit ES points depending on the setting in the PVLoop Settings dialog.
