ANTIARRHYTHMICS, CLASS I AND III
Preparations used in the treatment of arrhythmias should be classified in this
group. See also QC08 - Calcium channel blockers.
As in the ATC system, agents are listed according to the Vaughan Williams
classification of antiarrhythmics. The division of class I antiarrhythmics may
vary, depending on the literature used. The 3rd ed. of Avery’s Drug Treatment
(1987) and Drugs 31, 93 - 95, 1986 have been used as a basis for the ATC
classification.
Class II antiarrhytmics are assigned to group QC07 - Beta blocking agents, and
class IV antiarrhythmics to QC08 - Calcium channel blockers.
Combined preparations are classified at separate 5th levels using the
corresponding 50-series codes or, if not available, using the 5th level code 99.
