Abstract :
Background. Takotsubo cardiomyopathy is associated with increased risk of ventricular arrhythmias, atrial fibrillation, and
bradyarrhythmias. However, sinus node dysfunction is relatively infrequent in the setting of takotsubo cardiomyopathy. Case
Report. We are reporting a case of a 73-year-old woman with a history of asymptomatic sinus bradycardia who developed sick
sinus syndrome complicated by takotsubo cardiomyopathy. Conclusion. Acute symptomatic sick sinus syndrome in patients
with preexisting silent sinus node dysfunction can trigger takotsubo cardiomyopathy. Understanding precipitating factors of
takotsubo cardiomyopathy and identifying the patients at risk of life-threatening arrhythmia can help in refining risk
stratification and therapy planning. Patients with sick sinus syndrome complicated by takotsubo cardiomyopathy may benefit
from pacemaker implantation. However, evaluation on a case-by-case basis is mandatory.
