A case of long-lasting nodal arrhythmia and severe hypotension following DC
cardioversion for atrial flutter is presented. The patient, treated with t
he selective serotonin reuptake inhibitor sertraline and with sotalol, thio
pental and digoxin, showed no sign of organic disease or drug intoxication.
We suggest that drug interaction in combination with the DC shock and an a
ltered sympaticus/parasympaticus balance during anaesthesia provoked the in
cident.
