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)
