Tall P waves, S waves greater than 0.35 mV in lead II and greater than 0.05 mV in lead I, presence of S waves in leads I, II, III and aVF, and deep Q waves (>0.5 mV) in leads I, II, III and aVF are consistent with right-sided cardiac enlargement. | Tall P waves, S waves greater than 0.35 mV in lead II and greater than 0.05 mV in lead I, presence of S waves in leads I, II, III and aVF, and deep Q waves (>0.5 mV) in leads I, II, III and aVF are consistent with right-sided cardiac enlargement. |
