Summary
The Mason- નેકார் (M-L) lead system in treadmill exercise ECG may show ST-T wave changes mimicking ischemia. Careful evaluation of electrical axis and ST-T waves in leads II, III, and aVF is crucial for accurate diagnosis.
Area of Science:
- Cardiology
- Medical Imaging
- Exercise Physiology
Background:
- The Mason-Likar (M-L) lead system is commonly used for exercise electrocardiography (ECG) to detect myocardial ischemia.
- Routine treadmill exercise ECG with M-L leads can present ST-T wave patterns different from standard bipolar leads (II, III, aVF).
- These differences may lead to misinterpretation of myocardial ischemia during exercise testing.
