❓ Frequently Asked Questions
Q: What are the main ECG criteria for Left Ventricular Hypertrophy?
A: The main ECG criteria include increased QRS voltage in the limb leads (e.g., R wave in aVL > 11 mm) and precordial leads (e.g., S wave in V1 + R wave in V5 or V6 > 35 mm), along with associated repolarization abnormalities (ST-T wave changes).
Q: How accurate is ECG in diagnosing Left Ventricular Hypertrophy?
A: While ECG is a valuable tool, its sensitivity for detecting LVH is limited. False negatives are common. Combining ECG findings with clinical information and other diagnostic tests (e.g., echocardiography) improves diagnostic accuracy.
Q: What are the common causes of Left Ventricular Hypertrophy?
A: Common causes include hypertension (high blood pressure), aortic stenosis, hypertrophic cardiomyopathy, and less frequently, conditions like mitral regurgitation or coarctation of the aorta.
Q: How does hypertension lead to Left Ventricular Hypertrophy?
A: Chronic hypertension increases the workload on the left ventricle, causing it to pump against higher resistance. This increased workload leads to thickening of the heart muscle (hypertrophy) as the heart adapts to maintain adequate cardiac output.
Q: What are the potential complications of Left Ventricular Hypertrophy?
A: LVH can lead to several complications including heart failure, atrial fibrillation, ventricular arrhythmias, myocardial ischemia, and sudden cardiac death. Early detection and management are crucial to mitigate these risks.
Q: What is the treatment for Left Ventricular Hypertrophy?
A: Treatment focuses on addressing the underlying cause, such as managing hypertension with medications like ACE inhibitors or ARBs. Lifestyle modifications, including diet and exercise, also play a crucial role. In some cases, surgical intervention may be necessary for conditions like aortic stenosis.
