Abstract
Background: Early postoperative arrhythmias are a widely recognized complication of
cardiothoracic surgery in the pediatric populations with CHDs. They have potentially grave
consequences, particularly if they are not managed promptly. However, there remains lack of
information in Ethiopian setting regarding postoperative cardiac rhythm disturbances
although cardiothoracic surgeries have been performed since recently.
Objective: To assess the magnitude of early postoperative arrhythmia and its associated
factors among CHD patients who underwent cardiac surgery at the Cardiac Center-Ethiopia,
Addis Ababa, Ethiopia from January 1
st
, 2018 to December 31
st
, 2020.
Methodology: A facility-based, cross-sectional study was conducted at Cardiac CenterEthiopia,
Addis
Ababa.
Data
was
collected
using
a
structured
checklist,
and
then
entered
and
analyzed
using
SPSS
version
26.
Descriptive
analysis
along
with
chi
square
test
and
Student
t
test
analyses
were
employed
to
identify
factors
associated
with
development
of
arrhythmia.
A
p-value
<0.05
was
considered
significant.
Tables
and

to present
the
results.
Results: The study evaluated medical records of 202 pediatric CHD patients who underwent
cardiothoracic surgery. Their age ranged from 1 month to 14 years, and of all, females
represented 54.5% (110). Arrhythmia was documented in 16 (7.9%) of the patients, and
junctional ectopic tachycardia was the most common form of arrhythmia (43.8%).
Statistically significant difference between the arrhythmic and non-arrhythmic group were
noted in relation to cardiopulmonary bypass time (132.87 vs. 84.63mins) and aortic clamping
time (89.47 vs. 51.40 mins), with p value <0.05. Chi square test showed that cyanotic CHDs
and patients with TOF are at higher risk of developing post-surgery arrhythmia.
Conclusion: Early postoperative arrhythmias following surgery for congenital heart disease
are not uncommon in the paediatric population. Longer ischemic time, bypass time, cyanotic
heart diseases and presence of TOF were all risk factors that increased the incidence of
postoperative arrhythmias.
