<prompt> A new systolic murmur after Acute myocardial infarction may be due to all of the following Except:Complete hea blockRupture of Interventricular septumPapillary muscle dysfunctionIschemic cardiomyopathy  <response>: Answer is A Complete hea block Complete hea block iv not a cause for new onset systolic murmur after Acute _Myocardial Infarction. Cause of new systolic murmur after Acute Myocardial infarction Papillary muscle dysfunctionrupture causing severe mitral regurgitation Rupture of interventricular septum Right ventricular infarction and tricuspid regurgitation Free wall rupture Left ventricular outflow tract obstruction Note: Ischemic cardiomyopathy is defined as dilated cardiomyopathy in a subject with history of MI. This may lead to papillary muscle dysfunction and hence produce a new onset systolic murmur.
