As a result, you see a positive deflection in all of these leads, with lead II showing the most positive deflection as it is the most closely aligned to the overalldirection of electrical spread. If high blood pressure is the cause of LVH, medications such as diuretics, angiotensin receptor blockers (ARBs), beta-blockers, angiotensin-converting enzyme inhibitors (ACE inhibitors), and calcium channel blockers are used to lower blood pressure and prevent further enlargement of the left ventricle. First, analyze the QRS complex for both leads I and avF to determine if it is +ve (height of R wave > height of S wave), equiphasic (R wave = height of S wave), or negative (R wave height of S wave). Tests used to diagnose left ventricular hypertrophy may include: Lab tests. Disclaimer. What is left axis deviation on an ekg? Am scared.

Right axis deviation occurs when the QRS axis is shifted between 90 and 180 degrees. An abnormal ECG might indicate a variety of conditions. Left axis deviation (LAD) discovered in children via electrocardiogram (ECG) is uncommon but can be associated with heart disease (HD). Heart muscle contraction is preceded by a wave of electrical activity(depolarization) that flows through the the heart. This is mirrored by a positive QRS complex in lead I and a negative complex in leads aVF & II.
