12-lead ECGs before (A) and after (B) the operation. A) A surface ECG shows sinus tachycardia (105 eats/min). Right axis deviation (RAD) and increased R/S ratio in lead V1 suggest right ventricular hypertrophy. B) A surface ECG shows a similar rate of sinus tachycardia and RAD. ST elevations (arrows) are noted in limb leads II, III, aVF. ST depressions (arrow heads) in precordial leads (V1-2) suggest acute infero-posterior myocardial infarction.
