Why the study?
Does 123I-MIBG SPECT imaging detect irregular regional sympathetic innervation in patients with long QT syndrome compared to healthy controls?
Does 123I-MIBG SPECT imaging detect irregular regional sympathetic innervation in patients with long QT syndrome compared to healthy controls?
123I-MIBG SPECT imaging reveals reduced uptake and faster washout in the left ventricle of patients with long QT syndrome, suggesting regional sympathetic innervation abnormalities.
No takes yet. Share an insight, caveat, or question.
MIBG SPECT may identify sympathetic abnormalities in LQTS; hypothesis-generating for risk stratification, prospective validation required.
Müller et al. (1993) studied this question.
