Paroxysmal vagally mediated AV block with recurrent syncope
Clinical Cardiology
|June 1, 1985
Summary
Recurrent fainting spells in a mother and daughter were linked to paroxysmal complete atrioventricular block. This heart rhythm issue, potentially vagally mediated, occurred despite normal electrocardiograms between episodes.
Area of Science:
- Cardiology
- Electrophysiology
- Internal Medicine
Background:
- Paroxysmal complete atrioventricular (AV) block without electrocardiographic (ECG) abnormalities is an underrecognized condition.
- Recurrent syncope can present diagnostic challenges, particularly when initial ECGs are normal.
