Summary

Complete atrioventricular block, a heart rhythm issue, may precede Takotsubo syndrome. Pacemaker implantation resolved cardiac dysfunction, suggesting a potential causal link in this rare case.

Area of Science:

Cardiology
Electrophysiology
Cardiomyopathy

Background:

The link between complete atrioventricular (AV) block and Takotsubo syndrome (TTS) is recognized, but causality remains unclear.
Takotsubo syndrome, or broken heart syndrome, involves temporary weakening of the heart muscle.

Observation:

A 91-year-old female with a year-long untreated complete AV block developed Takotsubo syndrome.
Cardiac wall motion abnormalities were observed in the patient.

Findings:

Following permanent pacemaker implantation for the complete AV block, the patient's Takotsubo syndrome symptoms resolved.
The implanted pacemaker functioned normally during follow-up, and cardiac wall motion defects reversed.

Implications:

This case suggests a potential causal relationship where untreated complete AV block might precipitate Takotsubo syndrome.
Permanent pacemaker implantation may be a therapeutic option for Takotsubo syndrome in patients with concurrent complete AV block.
Further research is warranted to elucidate the pathophysiological mechanisms linking AV block and TTS.
