Abstract
Objective. The aims of this study were to
analyze the risk factors for and types of
new-onset arrhythmias in ICU (Intensive
care unit), and to evaluate their impact on
patient outcomes.
Methods. We studied 1051 patients who
were admitted to the two general ICUs
between December 2013 and February
2016. These patients were divided into two
groups: patients with new-onset arrhythmias
and patients without new-onset arrhythmias.
We compared the risk factors,
types and prognoses of new-onset arrhythmias
between these two groups.
Results. New-onset arrhythmias were observed
in 20.84% (n=219) of 1051 patients.
The main risk factors leading to arrhythmias
included age, emergency operation, past
cardiovascular disease, patients with multiple
systemic diseases, acute respiratory distress
syndrome, severe sepsis/septic shock,
acute renal dysfunction, cardiovascular
disease, electrolyte disturbance, patients
on ventilators, patients on vasopressors
and higher Acute Physiology and Chronic
Health Evaluation II scores (APACHE
II score) on ICU admission. Multivariate
logistic regression revealed that age,
emergency operation, severe sepsis/septic
shock, cardiovascular disease, electrolyte
disturbance, patients on ventilators and
those with higher APACHE II scores on
ICU admission, were all significantly associated
with new-onset arrhythmias. Arial
fibrillation was the most frequent arrhythmia.
ICU mortality in patients with newonset
arrhythmias was 22.37% (49 out of
219) compared with 3.61% (30 out of 832)
in patients without new-onset arrhythmias
(p<0.001). Among surviving patients, ICU
stay for those with new-onset arrhythmias
was longer than those without new-onset
arrhythmias (median stay of 10 days versus
5 days, p<0.001).
Conclusion. We found a high prevalence
of new-onset arrhythmias in ICU patients.
Arrhythmia, especially atrial fibrillation,
was a common complication in ICU patients
and was associated with increasing
length of ICU stay and higher mortality.
