Acquired complete heart block in young adults can occur without clear cause, affecting different heart areas. Treatment often involves pacemaker implantation for long-term management.
Area of Science:
- Cardiology
- Electrophysiology
- Internal Medicine
Background:
- Acquired complete heart block is uncommon in young adults.
- Etiology is often unclear in these cases.
- Understanding the anatomical location of the block is crucial for management.
Purpose of the Study:
- To present two cases of acquired complete heart block in young adults.
- To discuss the anatomical and functional abnormalities observed.
- To highlight the diagnostic and therapeutic considerations.
Main Methods:
- Case report presentation.
- Clinical evaluation and diagnostic workup.
- Pacemaker implantation for treatment.
Main Results:
- Two young adults presented with acquired complete heart block of unknown etiology.
- Abnormalities were located distal to the bundle of His in one patient and within the AV node and right bundle branch in the other.
- A significant time interval was noted between initial symptoms and definitive diagnosis.
Conclusions:
- Acquired complete heart block in young adults necessitates thorough investigation for underlying causes.
- The location of the conduction abnormality influences clinical presentation and management.
- Demand pacemaker implantation is an effective treatment for symptomatic patients.
