Electrocardiogram An electrocardiogram helps to establish the exact diagnosis and guides treatment, it may reveal: * Abnormal heart rhythms, such as bradycardia (slowed heart rate) * myocardial<unk>  (ST-elevation MI, STEMI, is usually more dangerous than non-STEMIs; MIs that affect the ventricles are usually more dangerous than those that affect the atria; those affecting the left side of the heart, especially the left ventricle, are usually more dangerous than those affecting the right side, unless that side is severely compromised) * Signs of cardiomyopathy Echocardiography Echocardiography may show poor ventricular function, signs of PED, rupture of the interventricular septum, an obstructed outflow tract or cardiomyopathy. File:UOTW 7 - Ultrasound of the Week 2.Ultrasound showing cardiogenic shock due to myocarditis File:UOTW 7 - Ultrasound of the Week 3.Ultrasound showing cardiogenic shock due to myocarditis Swan-Ganz catheter The Swan–Ganz catheter or pulmonary artery catheter may assist in the diagnosis by providing information on the hemodynamics. Biopsy When cardiomyopathy is suspected as the cause of cardiogenic shock, a biopsy of heart muscle may be needed to make a definite diagnosis. Cardiac index If the cardiac index falls acutely below 2.2 L/min/m2, the person may be in cardiogenic shock.
