Hypothesis
Can antitachycardia pacing effectively terminate ventricular tachycardia in patients with hypertrophic cardiomyopathy after ineffective shock therapy?
Conclusion
Antitachycardia pacing successfully terminated a ventricular tachycardia episode after five ineffective high-energy shocks in a patient with hypertrophic cardiomyopathy.
Supporting Evidence
- Implantable cardioverter defibrillators can terminate ventricular tachycardias painlessly with antitachycardia pacing.
- High-energy shocks are usually effective for terminating ventricular tachycardias in the absence of device dysfunction.
- Antitachycardia pacing can safely terminate 40-80% of fast ventricular tachycardias.
Takeaway
A woman with a heart condition had a fast heart rhythm that didn't stop after five strong shocks from her heart device, but it did stop when the device used a different method to pace her heart.
Methodology
Case report of a single patient with hypertrophic cardiomyopathy and an ICD who experienced ineffective shocks followed by successful antitachycardia pacing.
Limitations
The study is based on a single case, limiting generalizability.
Participant Demographics
48-year-old female with hypertrophic obstructive cardiomyopathy.
