Electrocardiographic changes in cerebrovascular hemorrhage

B J Yamour, M R Sridharan, J F Rice

    American Heart Journal
    |March 1, 1980
    PubMed
    Summary

    Cerebrovascular hemorrhage, particularly in the frontal lobe, can cause specific electrocardiographic (ECG) abnormalities like QT prolongation. These changes may stem from altered autonomic nervous system tone affecting the heart.

    Area of Science:

    • Neurology
    • Cardiology
    • Radiology

    Background:

    • Cerebrovascular hemorrhage can lead to various clinical manifestations.
    • Electrocardiographic (ECG) abnormalities are sometimes observed in patients with brain injuries.

    Purpose of the Study:

    • To describe electrocardiographic abnormalities associated with localized cerebrovascular hemorrhage.
    • To correlate specific brain hemorrhage locations with distinct ECG findings.

    Main Methods:

    • Review of electrocardiographic findings in patients with cerebrovascular hemorrhage.
    • Correlation of ECG abnormalities with computerized tomography (CT) scan findings to localize the hemorrhage.

    Main Results:

    • Frontal lobe hemorrhages are linked to QT prolongation and neurogenic T waves.

  • Brain stem hemorrhages are associated with noncardiogenic pulmonary edema and atrial fibrillation.

    • Conclusions:

    • Specific ECG abnormalities can indicate the location of cerebrovascular hemorrhage.
    • Orbito-frontal lesions may influence cardiac autonomic tone, leading to ECG changes via the stellate ganglia.
