Get your blood pressure checked at least every two years if you're 18 and older. ECG demonstrates many of the features of chronic pulmonary disease: Rightward QRS axis (+90 degrees)Peaked P waves in the inferior leads > 2.5 mm (P pulmonale) with a rightward P-wave axis (inverted in aVL) Clockwise rotation of the heart with a delayed R/S transition point (transitional lead = V5). Left Axis Deviation = QRS axis less than -30. This is reflected by a QRS complex positive in lead I and negative in leads aVF and II. Left ventricular hypertrophy in athletes and hypertensive patients. Cardiomegaly (mild) is more common in people with an uncorrected complete aortic vein disorder and pulmonary disease than in those with complete vascular dementia. Hemodynamic studies are frequently used to assess PVR in older patients. Its often not serious if you have no underlying conditions. There is also extreme left axis deviation with small r-waves in inferior leads followed by a large S-wave, and a small q-wave in aVL with a large R-wave; this is a left anterior . Ommen SR, et al. [3] For example, if left ventricular hypertrophy is the cause of LAD, symptoms can include shortness of breath, fatigue, chest pain (especially with exercise), palpitations, dizziness, or fainting.
