ECG Quiz Documentation

Each interpretation in the ECG Quiz contains a textual explanation of the interpretation located in the Explanation Section on the Results Page. The objective of the explanation is to provide greater detail on the interpretation for the user. In addition, to assist with identifying specific items in the ECG in the explanations, the ECG Quiz provides graphical annotations in the ECG display.

Adding graphical annotations to ECGs provides several benefits for explanation purposes. Here are some of the advantages:

Enhanced clarity and understanding

Graphical annotations help highlight specific features or abnormalities in an ECG, making it easier for you to understand the underlying information. Annotations are used to mark important points, waveforms, intervals, or segments, making it clearer and more comprehensible, especially for those who may not have extensive ECG interpretation experience.

Accurate identification of key events

Adding annotations to an ECG precisely identifies and labels important events, such as P waves, QRS complexes, ST segments, or T waves. This assists in the accurate interpretation of the ECG and allows for better communication and documentation of findings.

Facilitation of teaching and learning

Graphical annotations are particularly useful in educational settings, where ECGs are used to teach students or trainees about cardiac rhythms and abnormalities. Annotations help focus attention on specific elements, aid in explaining concepts, and facilitate the understanding of ECG interpretation principles.

Communication and collaboration

When sharing ECGs between healthcare professionals, graphical annotations serve as visual cues, drawing attention to specific areas of interest or concern. They provide a means of highlighting specific findings or abnormalities, making it easier to convey important information during consultations, discussions, or referrals, improving communication and collaboration.

Documentation and reference

Annotations serve as a permanent record or reference point for future analysis or comparisons. By marking significant features or abnormalities, healthcare professionals can refer back to the annotations for follow-up assessments, treatment evaluations, or longitudinal monitoring. This promotes continuity of care and assists in tracking changes in the ECG over time.

In the Explanation Section on the Results Page, the button will be enabled if graphical annotations are available. Clicking on this button will toggle the display of graphical annotations in the ECG display.

Clicking on the button toggles the display of annotations on the ECG tracing. An example of annotations available are shown in Fig. 2.
