The electrocardiogram in aortic valvular atresia.

T J Von Rueden, J H Moller

    Chest
    |January 1, 1978
    PubMed
    Summary

    This review of aortic valvular atresia ECGs found rare occurrences of Wolff-Parkinson-White syndrome and complete right bundle-branch block. Left axis deviation and left ventricular hypertrophy were also noted as infrequent findings.

    Area of Science:

    • Cardiology
    • Pediatric Cardiology
    • Cardiac Electrophysiology

    Background:

    • Aortic valvular atresia is a severe congenital heart defect.
    • Electrocardiogram (ECG) findings in aortic valvular atresia can vary.
    • Understanding ECG patterns is crucial for diagnosis and management.

    Purpose of the Study:

    • To review and identify unusual electrocardiogram (ECG) patterns in patients with aortic valvular atresia.
    • To document the prevalence of specific arrhythmias and conduction abnormalities.

    Main Methods:

    • Retrospective review of electrocardiograms (ECGs) from 27 patients diagnosed with aortic valvular atresia.
    • Analysis of ECG findings, including arrhythmias, conduction blocks, and chamber hypertrophy.

    Main Results:

    • Several patients exhibited unusual ECG patterns.
    • Two patients presented with Wolff-Parkinson-White (WPW) syndrome.
    • One patient showed complete right bundle-branch block; rare instances of left axis deviation and left ventricular hypertrophy were observed. No Q waves were seen in lead V6.

    Conclusions:

    • Aortic valvular atresia can be associated with diverse and sometimes rare ECG abnormalities.
    • Wolff-Parkinson-White syndrome and right bundle-branch block are notable findings in this patient cohort.
    • The absence of Q waves in V6 warrants further investigation in the context of this condition.
