[{'content': 'True about subendocardial haemorrhage is all except- \nSelect and explain. \nA. May be seen after head injury, B. Involves RV wall, C. Continous pattern of sheet, D. Flame shaped hemorrhages', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Subendocardial hemorrhages is a striking feature seen in many autopsy cases. It was believed to be an\xa0insignificant finding without any particular reference to the cause of death.\nHowever latest reports have indicated that presence of subendocardial hemorrhages is an indicator of exsanguination\xa0and head injury\nWhen subendocardial hemorrhages are present on autopsy, the mechanism of death is believed to be\xa0exsanguination or head injury\nCardiac lesions secondary to non cardiac injuries are believed to be caused due to massive production of\xa0catecholamine due to severe sympathetic stimulation\nThe hemorrhages in the heart are strictly confined to the subendocardial tissue of the left ventricle. a fact, which\xa0distinguishes them on the one hand from hemorrhages seen in anoxia which tend to be subpericardial and\xa0subpleural and on the other from the more wide spread hemorrhages some of which may also occur in sub\xa0endocardial tissue seen in severe toxemias, septicemias, blood dyscrasias and uremia\nHemorrhages occur in three sites in the left ventricle\nMiddle third of the interventricular septum is the most common site involved\nBase of the papillary muscle is the second most common site of involvement\nPosterior wall of the left ventricle is the third most common site of involvement Pathology\nThe hemorrhages are flame shaped, confluent and tend to occur in one continuous sheet rather than patches.When the bleeding is severe, it may raise the endocardium’s into a flat blister.', 'role': 'assistant'}]
