dc.description.abstract
Background Myocardial infarction (MI) alters spatial features of the surface electrocardiogram. Spatial variance of the T-wave (SVT) describes the interlead dispersion about a mean T-wave morphology. SVT was linked to arrhythmia vulnerability and sudden cardiac death. Methods Herein, we studied the evolution of SVT over the healing (MI7, up to 7 days after MI) and healed (MI60, from 60 days on post-MI) stages. A control group (n = 49) was compared to paired MI7 and MI60 groups (n = 39). Five representative sets of frontal and precordial leads were analyzed: I−II−III, V1 − V2 − V3, V4 − V5 − V6, aVF − V2 − V5 and II − aVF − V5. Results SVT index significantly increased at MI7 (p < 0.05) in four out of five sets and returned towards control values at MI60 (p = NS). The preferential combination of ECG leads resulted aVF − V2 − V5, since it showed the strongest modulation. In order to test whether such a modulation was maintained on the presence of ventricular tachycardia and/or ventricular fibrillation (VT/VF), recordings from VT/VF patients were also analyzed. SVT modulation was lost in the VT/VF group, significantly increasing from controls at MI60 (p < 0.05) for all sets of leads tested. Conclusions SVT modulation over MI7 and MI60 would signal a good recovery from MI, whereas lack of this modulation could herald a VT/VF event.
