Differences Between 3-Lead and 12-Lead ECG
Understanding the distinctions between a 3-lead and a 12-lead ECG:
3-Lead ECG
A 3-lead ECG focuses on three areas of the heart, despite having four leads.
Limitations of 3-Lead ECG
Diagnostically, a 3-lead ECG may not provide enough information to determine:
- Pre-existing heart conditions
- Medication reactions
- Impact of illness on the heart
12-Lead ECG
A 12-lead ECG provides a broader overview of the heart from different angles.
Diagnostic Benefits of 12-Lead ECG
Performing a 12-lead ECG helps in:
- Obtaining a comprehensive diagnostic picture
- Identifying existing problems or concerns
- Monitoring medication effects
- Assessing the impact of illness on the heart
Transition to 3-Lead Monitoring
After conducting a 12-lead ECG and addressing any issues, it is acceptable to continue monitoring with only a 3-lead.
Monitoring with 3-Lead ECG
When monitoring with a 3-lead ECG, pay attention to any changes in the leads displayed on the defibrillator.
Transition to 12-Lead ECG
If changes occur in the 3-lead, perform another 12-lead ECG to obtain a more detailed picture.
Real-Time Picture and Diagnosis
If changes are observed, press the 12-lead button to print out a real-time picture of the heart's activity, enabling further analysis, treatment adjustments, or revised diagnoses.
