What indicates a positive outcome on a voltage map during atypical flutter evaluation?

• A. Red indicates dead tissue
• B. Red indicates health
• C. Purple indicates high voltage
• D. Purple indicates scar tissue

Answer: (A)

In the context of voltage mapping during an atypical flutter evaluation, a positive outcome is typically indicated by the detection of healthy myocardial tissue. This is represented by specific color coding on the voltage map. The correct answer, which states that red indicates dead tissue, is often used in voltage maps to denote areas with low or non-existent electrical activity, highlighting regions where myocardial tissue is not functioning properly. A positive outcome generally involves identifying good-quality tissue for successful ablation or intervention, allowing practitioners to achieve targeted results. In standard voltage maps, healthy and functional myocardium is often represented by colors other than red, reflecting a positive outcome. Thus, understanding the significance of the color coding is crucial for interpreting a voltage map correctly in the context of atrial flutter evaluations.
