A patient aged 60 having a complaint of nocturnal angina was described. There were no apparent clinical findings, except for very feeble heart sounds and .a diffuse maximal cardiac impulse. The electrocardiogram showed evidence of both anterior as well as postero-inferior infarction. ST segments were elevated in V1V2V3V4` suggesting some extention of the dyskinesia on the anteriolateral wall.`T` waves were inverted in V5 and V6` suggesting deterioration of left ventricular function. An old anterier myocardial infarction, , healed posterior myocardial infarction, increasing stenosis of left circumflex artery and increasing stenosis of right coronary artery were diagnosed. The exact nature could only be decided upon by the findings at operation, therefore a "Bypass operation" was advised.
