Af þessu má því sennilega draga þá ályktun
að óregla á hjartslætti, þótt mjög algeng sé í
svæfingum og deyfingum þurfi sjaldan að leiða
til skaða, sé vel fylgst með hjartslættinum,
orsaka óreglu leitað og hún meðhöndluð fljótt

SUMMARY
A retrospective screening of 693 anesthetic admini-
strations in a general surgical population at Univer-
sity of Wisconsin Hospitals, Madison showed 39
cases that had by definition significant cardiac
arrhythmias during anesthesia and operation. Of
these 6 had severe bradycardia, 6 had supraventri-
cular tachycardia, 1 had ventricular tachycardia, 2
had very frequent premature atrial contractions, 23
had frequent premature ventricular contractions
and 1 had atrioventricular dissociation.
The etiology of cardiac arrhythmias during anest-
hesia in general and in these cases in particular is
explored and discussed.
None of these 39 patients suffered permanent
damage or death related to these arrhythmias which
attests to the importance of their early recognition
and treatment.
