[Recognizing rare cardiac diseases by electrocardiogram]

Area of Science:

• Cardiology
• Medical Diagnostics

Background:

• Rare cardiac diseases pose diagnostic challenges.
• Sudden cardiac death (SCD) often results from undiagnosed genetic heart conditions.
• Electrocardiogram (ECG) is a non-invasive diagnostic tool.

Purpose of the Study:

• To highlight the clinical significance of ECG in identifying rare cardiac diseases.
• To emphasize ECG's role in early diagnosis of channelopathies and Wolff-Parkinson-White syndrome.
• To underscore the importance of ECG in preventing SCD within families.

Main Methods:

• Review of clinical significance of ECG findings.
• Illustration of typical ECG patterns for specific cardiac conditions.
• Discussion of late diagnoses and their consequences.

Main Results:

• ECG effectively detects Wolff-Parkinson-White syndrome.
• ECG identifies various channelopathies: long QT syndrome, short QT syndrome, Brugada syndrome, and catecholaminergic polymorphic ventricular tachycardia.
• ECG also reveals findings in idiopathic ventricular tachycardia, arrhythmogenic right ventricular dysplasia, digitalis intoxication, hyperkalemia, acute cor pulmonale, and left ventricular hypertrophy.

Conclusions:

• ECG is an indispensable tool for diagnosing a spectrum of rare cardiac diseases.
• Timely ECG interpretation can facilitate early diagnosis and management, potentially preventing SCD.
• Recognizing ECG patterns aids in identifying affected individuals and families at risk.
