Which of the following is an indication for performing a 12-lead EKG?

Explanation:
A 12-lead EKG is used when there is suspicion of a dysrhythmia or other cardiac issue, because it records the heart’s electrical activity from multiple angles to reveal rhythm, rate, conduction problems, and signs of ischemia or infarction. When a patient presents with an irregular heartbeat or palpitations, the ECG helps confirm the presence and type of rhythm disturbance and guides treatment. Dehydration, facial laceration, or normal vital signs do not by themselves mandate a 12-lead ECG. Dehydration may affect electrolytes and rhythm in some cases, but it’s not a direct cardiac indication. A facial laceration is a non-cardiac injury, and normal vital signs suggest there is no immediate electrical abnormality needing an ECG.
