May support QTc dispersion for early risk stratification in subarachnoid haemorrhage; hypothesis-generating and requires prospective validation.
Does increased QTc dispersion predict the development of cardiorespiratory compromise in patients with severe subarachnoid haemorrhage?
Increased QTc dispersion within 24 hours of severe subarachnoid haemorrhage is associated with subsequent cardiorespiratory compromise, suggesting its potential utility as an early prognostic marker.
Macmillan et al. (2005) studied this question.
