❓ Frequently Asked Questions
Q: What are the main ECG criteria for Left Ventricular Hypertrophy?
A: The main ECG criteria for LVH include increased QRS amplitude (S wave in V1 + R wave in V5 or V6 > 35 mm), ST-segment depression, and T-wave inversion in lateral leads.
Q: How accurate is ECG in diagnosing Left Ventricular Hypertrophy?
A: While ECG is a useful initial screening tool, its sensitivity in diagnosing LVH can vary. Echocardiography is often used for confirmation and more accurate assessment.
Q: What is the significance of ST-T wave changes in LVH?
A: ST-segment depression and T-wave inversion are common findings in LVH and can indicate repolarization abnormalities due to increased ventricular mass.
Q: Can hypertension cause Left Ventricular Hypertrophy?
A: Yes, chronic hypertension is a major cause of LVH as the heart has to work harder to pump blood against increased resistance.
Q: What is the role of echocardiography in diagnosing LVH?
A: Echocardiography is considered the gold standard for diagnosing LVH, as it allows direct measurement of left ventricular wall thickness and chamber size.
Q: Are there any specific ECG patterns in LVH with strain?
A: Yes, LVH with strain typically shows ST-segment depression and T-wave inversion in the lateral leads (V5, V6, I, aVL), indicating repolarization abnormalities.
