Depolarization of the ventricles occurs via the bundle of His and normally com- pletes within 0 sildigra 50mg on line erectile dysfunction blood pressure medications side effects. Right bundle branch block is common after surgical repair of a ventricular septal defect due to damage of the right bundle branches which course in close proximity to the edge of the ventricular septal defect generic sildigra 120mg visa erectile dysfunction remedy. Superior axis deviation is a unique finding in patients with an atrioventricular canal defect due displacement of the bundles of His as a result of the atrial and ventricular septal defects (Fig. This is due to abnormal position of con- duction pathways as they are displaced by the inlet ventricular septal defect 48 Ra-id Abdulla and D. Alteration in T wave morphology may represent abnormal repolarization due to ischemia or abnormal electrolytes. Left Atrium Left atrial enlargement leads to a larger atrial mass which requires a longer period of depolarization. In addition, the larger than normal, atrial mass causes the depolarization to occur in different directions throughout the cycle leading to a bifid or biphasic P-wave. Therefore, neonates and young children have a proportionally larger right ventricular mass (as compared to the left ventricle) than is seen in older children and adults. An enlarged right atrium will cause the P-waves to be taller than normal (>2 mm in small children and >3 mm in older children and adults. This is followed by a second R-wave (R¢) which reflects the large right ventricular mass 3 Electrocardiography – Approach and Interpretation 51 reflect right ventricular hypertrophy in older children and adults. The downward progression of the R-wave into an S-wave may be over- come by continuing right ventricular depolarization, causing a reversal in the direction of electrical charges and a second upward wave in the right chest leads, manifesting as an R¢. Right ventricular hypertrophy leads to a tall R-wave in V1 and a deep S-wave in V6 due to the enlarged right ventricular mass. Although an rSr¢ pattern is normal in young children, if the second R-wave is taller than the initial R-wave, this reflects a larger right ventricular mass than normal. The initial depolarization of the ventricles starts in the ventricular septum in the same direction as that of the right ventricular wall mass as recorded in V1 and V2 resulting in an initial R-wave deflection in these leads without a Q-wave. In patients with right ventricular hypertrophy there may be deviation of the plane of the ventricular septum leading to a small Q-wave with resultant qR pattern in V1 and V2 52 Ra-id Abdulla and D. Similar to changes leading to an rsR¢ pattern described above, the right ventricular electrical domi- nance may be significant enough to completely mask any left ventricular forces in the right chest leads, resulting in a pure R-wave configuration (Fig.
