Unfortunately, it is often difficult to measure. The isovolumic contraction and relaxation phases exactly It does not have too. | Unfortunately, it is often difficult to measure. The isovolumic contraction and relaxation phases exactly It does not have too. | ||
What you can use is the time between the conclusion of the TV and access the back of the TV ( tricuspid closing to opening time). This can be determined by measuring between the end of the A wave and the beginning of the next E -top on the TV influx signal on the recording AP4CH the duration. | What you can use is the time between the conclusion of the TV and access the back of the TV ( tricuspid closing to opening time).

If you are also in the measurement of RV ejection in Plax shot, here you can quickly and easily determine the total duration of the isovolumic times. This is because the difference between the TV closing to opening time and the EJECT time. Share time again by the EJECT time and you have the MPI. | If you are also in the measurement of RV ejection in Plax shot, here you can quickly and easily determine the total duration of the isovolumic times.
