Wall Motion Index Score
The wall motion score index was calculated by sum of all segment scores divided by the number of segments assessed. 16 segments were assessed with scores as followed: 1 = normal, 2 = hypokinesis, 3 = akinesis, 4 = dyskinesis and 5 = aneurysmal (11). Two of the three studies that assessed for wall motion score index demonstrated normal values in myocarditis and control populations, particularly as they only included patients with a normal left ventricular ejection fraction. One study showed that the myocarditis population had a higher wall motion score index compared to controls (1.6±0.7 vs 1, p<0.01)
