As an expert in medical diagnostics, particularly in the field of electrocardiography (ECG), I can provide you with an accurate answer to your question. The term "12 lead" refers to a standard ECG that records electrical activity from 12 different angles of the heart. However, the question seems to be asking about the duration of time that these leads are used, which is typically measured in minutes, not seconds.
In a standard ECG, the leads are applied to the patient and remain in place for the duration of the test, which usually lasts around 10 seconds. This is enough time to capture a full cardiac cycle and provide a comprehensive view of the heart's electrical activity.
So, the answer to your question is that a 12-lead ECG is typically recorded for about 10 seconds.
