What should clinicians visually monitor to avoid misinterpretation in ECG?

Clinicians should visually monitor the baseline and T wave morphology in an ECG to avoid misinterpretation because these aspects are crucial indicators of underlying cardiac conditions. The baseline provides context for assessing any changes in the ECG, allowing for the identification of artifacts or fluctuations that can lead to misinterpretations. T wave morphology, in particular, can indicate several conditions, including ischemia and electrolyte imbalances. Abnormalities in T wave shape, direction, or height are often key markers for cardiovascular issues.

By focusing on these elements, clinicians can gain clearer insights into the heart's electrical activity and detect potential problems early, ensuring more accurate diagnoses and effective treatment. Monitoring T wave changes in conjunction with the baseline can help differentiate between normal variations and pathological conditions, thereby enhancing the clinical relevance of the ECG readings.
