Loading annotations to be edited

To load annotations from `100s.qrs' into WAVE , click right on \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~File~\ensuremath{\nabla}~}, and click left on the Load... selection in the File menu.
Figure 2.3: The Load window.

\end{figure}
The Load window (see figure 2.3) appears. It contains text items that specify a record and and an annotator name. Click left next to the Annotator field, type `qrs', and, as always, press \Ovalbox{\small\sf Enter}. The contents of `100s.qrs' are loaded into WAVE , and annotations appear in the signal window. The title bar changes to indicate the annotator name. The Load window also contains items that specify the name of the calibration file and the database path you will not need to change these items for this exercise. You may dismiss the Load window or leave it up as you wish.

If you have looked through the record using the navigation buttons, use them now to return to the beginning of the record. The time indicator in the lower left corner of the signal window should read `0:00'. Since the \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Mark QRS complexes~} button only produces `N' (normal) beat labels, the eighth beat in the window (an atrial premature beat) is mislabelled. In the next part of this exercise, we will correct this label.
