Myokarditt ekg The most common ECG abnormalities seen in myocarditis are: Sinus tachycardia Non-specific ST segment and T waves changes Other ECG changes are variable, and may include: Prolonged QRS QT prolongation Diffuse T wave inversion Ventricular arrhythmias AV conduction defects. 1 myokarditt prognose 2 Pericarditis refers to inflammation of the pericardium, and myocarditis refers to inflammation of the myocardial (muscle) tissue. However, it is often difficult to differentiate pericarditis and myocarditis, and they tend to accompany each other. 3 myokarditt varighet 4 Myocarditis is an inflammatory disease of cardiac muscle that is caused by a variety of infectious and noninfectious conditions (table 1) [ 1 ]. It can be an acute, subacute, or chronic disorder, and may present with focal or diffuse involvement of the myocardium. Myocarditis can be produced by a variety of infectious and noninfectious causes. 5 Mayo Clinic Overview Myocarditis Enlarge image Myocarditis is inflammation of the heart muscle (myocardium).

Symptoms can include shortness of breath, chest pain, decreased ability to exercise, and an irregular heartbeat. [1] The duration of problems can vary from hours to months. 7 perikarditt 8 EKG viser gjennomgående ST-T-forandringer i EKG og kan være vanskelig å skille fra STEMI. 9 Myokarditt underdiagnostiseres ofte, men markører for skade på hjertemuskelen, ekkokardiografi og EKG er til god hjelp for å stille. 10
