9.1. ECG View-Plugin

The ecg view-plugin displays ECG and ECG related information (e.g. type of the heart beat, RR interval). The user can edit the evaluation of the ECG, he can insert or delete a beat or he can change the type of the beat. Additionally he can "create" ECG specific selections which can be helpful while inspecting/correcting an automatic evaluation.

If the user wants to edit a beat, the beat has to be selected first by clicking in the area around the position of the beat (marked by the beat annoation). The current selected beat is highlighted by a bold beat annotation and the cursor (vertical line) is on the postion of the beat. After selecting a beat the following actions can be done:

• 'd': delete current selected beat

• 'n': mark current selected beat as normal

• 'v': mark current selected beat as ventricular

• 'x': mark current selected beat as artifact

If the user wants to insert a beat, the position has to be marked by the cursor by clicking at the wanted position. Then use one of the following keys to insert a beat:

• 'n': insert a normal beat

• 'v': insert a ventricular beat

• 'x': insert an artifact

The following ECG specific selections are available (press the key while the ecg view has the input focus):

• 'k': select all beats sorted with the shortest RR interval first

• 'l': select all beats sorted with the longest RR interval first
