The first step in troubleshooting an ECG recording that shows no discernible cardiac information is to check the leads. This is crucial because leads are responsible for transmitting the electrical signals from the heart to the ECG machine. If there is a poor connection, faulty lead placement, or a problem with the leads themselves (such as broken wires or poor contact with the skin), it can result in a lack of clear cardiac data. By ensuring that the leads are properly connected and functioning, you can determine if the issue lies with the recording setup or if further investigation is needed.

Other options, such as replacing batteries or ordering a replacement monitor, may be considered later if checking the leads does not resolve the issue. Documenting the time of the recording, while important in a clinical context, does not address the immediate technical problem of the ECG not displaying any data, making it a less relevant first step in troubleshooting.
