Examples from two patients (A and B) showing RT-PC velocity data as analysed by the software plugin. Each cardiac cycle is marked by vertical grey line and E-wave peak maximum velocity within each cardiac cycle is marked by a blue circle. Maximum and minimum peak velocity levels within that interval are shown as horizontal red and green lines, respectively. The vertical blue lines denote the 10-second interval showing the lowest velocity variation. Patient A had a variation of 7% and patient B was the patient with 20 mm pericardial effusion and a variation of 34%. Patient A had a heartrate of 54 beats/min and patient B had a heartrate of 88 beats/min. Due to a relatively high heart rate patient B had partial E and A-wave fusion.
