What is the optimal serum potassium level in cardiovascular patients?
review by 2 pharmacologistsin Dundee, UK: McDonald JE, Struthers AD J Am Coll Cardiol 2004;43:155-161.
This figure, from Norderhaug, et al.Circulation 1985; 71;645-9, shows the probability of VT as a functionof serum potassium. Incidence is quite low at potassium greater than4.5.
