1. PURPOSE AND SCOPE

The purpose of this document is to establish the standardized clinical protocol for the acquisition of a 12-Lead Electrocardiogram (ECG) to ensure diagnostic quality, patient safety, and regulatory compliance. This procedure applies to all [___________] (e.g., nursing staff, cardiology technicians, medical assistants) authorized to perform cardiac monitoring.

2. PATIENT IDENTIFICATION AND PREPARATION

Prior to the commencement of the procedure, the practitioner must verify the patient’s identity using at least two (2) clinical identifiers.

• Patient Name: [___________]
• Date of Birth: [___________]
• Medical Record Number (MRN): [___________]
• Ordering Physician: [___________]

Clinical Contraindications: Before proceeding, the practitioner must confirm there are no contraindications such as [___________] (e.g., severe skin trauma, allergic reaction to electrode adhesive).

3. EQUIPMENT SPECIFICATIONS

The following equipment must be inspected and calibrated per the manufacturer’s specifications:

• ECG Machine Model/Serial Number: [___________]
• Lead Cable Integrity Verified: [ ] Yes / [ ] No
• Electrode Expiration Date: [___________]

4. CLINICAL PROCEDURE STEPS

1. Patient Positioning: The patient shall be positioned in a [___________] (e.g., supine/semi-fowler’s) position to minimize artifact.
2. Skin Preparation: The electrode sites must be cleansed with [___________] (e.g., alcohol prep, skin abrading agent) to ensure optimal signal impedance.
3. Electrode Placement: Electrodes must be placed according to the International Standard for 12-Lead ECG placement (Wilson’s Central Terminal).
4. Lead Verification: Ensure all leads are secured.
   • V1: 4th intercostal space, right sternal border.
   • V2: 4th intercostal space, left sternal border.
   • V4: 5th intercostal space, mid-clavicular line.
   • V3: Midway between V2 and V4.
   • V5: Anterior axillary line, level with V4.
   • V6: Mid-axillary line, level with V4.

5. ACQUISITION AND QUALITY CONTROL

• Filter Settings: [___________] (e.g., 0.05–150 Hz standard).
• Report Verification: The practitioner shall review the tracing for baseline wander, muscle tremor, or power-line interference.
• Technical Notes: [___________]

6. CLINICAL DISPOSITION

The acquired data has been transmitted to: [___________] (e.g., Cardiology Information System/Physician Inbox).

Action Taken: [ ] Routine Transmission [ ] Urgent Over-read Requested (Reason: [___________])

Roles and responsibilities

Procedure

1. Verify the patient identity using [Number] distinct patient identifiers before starting any preparation steps. (Responsible: [Attending Nurse])
2. Explain the electrocardiogram procedure to the patient and answer any immediate clinical questions. (Responsible: [Attending Nurse])
3. Position the patient in a comfortable supine orientation on the examination table at [Angle] degrees. (Responsible: [Cardiac Technician])
4. Expose the chest, wrists, and ankles completely while maintaining patient privacy using [Tool]. (Responsible: [Attending Nurse])
5. Cleanse the electrode placement sites with alcohol wipes to reduce skin resistance and signal artifact. (Responsible: [Cardiac Technician])
6. Attach the four limb leads to the fleshy parts of the arms and the legs securely. (Responsible: [Cardiac Technician])
7. Place the six precordial chest leads across the designated intercostal spaces from position [Position] to position [Position]. (Responsible: [Cardiac Technician])
8. Program the electrocardiogram machine by entering the patient identification number, age, and current medications. (Responsible: [Cardiac Technician])
9. Instruct the patient to remain completely still and breathe normally during the active rhythm tracing capture. (Responsible: [Cardiac Technician])
10. Press the acquisition button to record the twelve lead electrocardiogram tracing for a duration of [Number] seconds. (Responsible: [Cardiac Technician])
11. Review the printed tracing for baseline wander, electrical interference, or mislabeled leads before removing equipment. (Responsible: [Quality Supervisor])
12. Disconnect the lead wires, remove the electrodes, clean the skin sites, and assist the patient to a sitting position. (Responsible: [Attending Nurse])
