Concomitant right ventricular infarction (40% of patients); these patients may develop severe hypotension in response to nitrates Significant bradycardia due to second or third-degree AV block (20%) Posterior infarction due to extension of infarct area. ECG diagnostic criteria ST elevation in leads II, III, aVF Hyperacute T waves may precede these changes Reciprocal ST depression in aVL Progressive development of Q waves in II, III, aVF Which Artery is the Culprit? Inferior STEMI can result from occlusion of any of the three main coronary arteries: Dominant right coronary artery (RCA) in 80% of cases Dominant left circumflex artery (LCx) in 18% Occasionally, a “type III” or “wraparound” left anterior descending artery (LAD), producing the unusual pattern of concomitant inferior and anterior ST elevation #heartattack #heartattackgrill #heartattacksurvivor #igheartattack #sheerheartattack #miniheartattack #heartattackonaplate #heartattacks #heartattackwaitingtohappen #demilovatoheartattack #heartattackfood #heartattackburger #pinksugarheartattack #gavemeaheartattack #aoaheartattack #flashbackheartattack #ialmosthadaheartattack #heartattackcity #givingmeaheartattack #heartattackman #heartattackhill #heartattackandvine #heartattackrecovery #instantheartattack #heartattackcentral #heartattackkids #miniheartattacks #heartattackprevention #havingaheartattack #heartattackonabun #givemeaheartattack #nearlyhadaheartattack #seriousasaheartattack #gonnagivemeaheartattack #heartattackproof #almostgavemeaheartattack #minorheartattack #ihadaheartattack #givingmomaheartattack #mildheartattack
