Summary
Repetitive fainting spells may indicate long QT syndrome, even with initially normal ECGs. A single normal QT interval measurement should not exclude this serious cardiac condition.
Area of Science:
- Cardiology
- Electrophysiology
- Internal Medicine
Background:
- Repetitive syncopal attacks are a common clinical presentation.
- Long QT syndrome (LQTS) is a potentially life-threatening arrhythmia disorder.
- Electrocardiogram (ECG) is crucial for diagnosing cardiac conditions.
