Repeat the Find cycle steps as briefly summarized below.

Manually removing duplicate event place markers

To remove extra systole and diastole events, use the tool by right clicking on the extra event markers. Systole and diastole events should only be at the peak and lowest points of each cycle respectively.

...

Click on “Clear Event” to remove the event. You should have to do this twice since the extra events automatically come in pairs. Check to make sure you delete both the systole and diastole events. You can also click on “Edit Event” to see the selected event and the event for all events.

...

Manually adding systole or diastole events

To add systolic or diastolic events, use the event marker set to add a hemodynamics “Systole” or “Diastole'' marker. Left click and hold down on the flag icon, then select “Hemodynamics” => “Blood Pressure” => “Systole” or “Diastole”

...

Once you have selected what you want to add, simply click on areas where event markers were missed. It is easiest to do all the systole markers first and then all the diastole markers.
