What is the first step in transmitting a 12-Lead ECG?

The first step in transmitting a 12-Lead ECG is to prepare the skin. Proper preparation of the patient's skin is crucial for obtaining an accurate and high-quality ECG. This preparation often involves cleaning the skin where the leads will be placed. Removing any lotions, oils, or dirt helps improve electrode adhesion and ensures that the electrical signals from the heart are captured clearly without interference.

By preparing the skin, you eliminate issues that could result in artifacts on the ECG, which can complicate diagnosis and treatment. Once the skin is prepared, you can proceed to correctly place the leads, but the initial step ensures that the entire process is set for success.
