Common electrocardiographic findings include ST-T wave abnormalities and left ventricular hypertrophy, axis deviation (right or left), conduction abnormalities (P-R prolongation … For example, the identification of segmental lateral ventricular hypertrophy cannot be accomplished with echocardiography alone. … The mid-septal bulge aggravates the malposition of the valve and redirects outflow so that it comes from a lateral and posterior direction.
Gradual return to normal ECG findings or development of abnormal Qwaves confirm the diagnosis. … These changes are seen on gross pathology and cannot be predicted by the presence or absence of Qwaves on an ECG. … In addition to a rise in biomarkers, a rise in the ST segment, changes in the shape or flipping of T waves, new Qwaves, or a new left bundle branch block can be used to diagnose … 
Leads V7-V9 show the classical aspect of ST elevation and Qwaves. … cardiac ischemia diagnosis, but posterior myocardial infarction is not represented directly on the classical 12 lead recording: horizontal ST depression with tall R and T waves … 
Acute myocarditis is a potentially life-threatening inflammatory disorder of the myocardium, most commonly caused by viral pathogens such as coxsackie A and B, as well as influenza viruses and other enteroviruses, but an array of infections and autoimmune etiologies have been described. Chest pain, dyspnea, and…
