Electrocardiograph abnormalities in intracerebral hemorrhage

Area of Science:

• Neurology
• Cardiology
• Medical Imaging

Background:

• Electrocardiography (ECG) abnormalities are well-documented in ischemic stroke and subarachnoid hemorrhage.
• Limited data exists on ECG findings in patients with intracerebral hemorrhage (ICH).

Purpose of the Study:

• To investigate the prevalence and types of ECG abnormalities in ICH patients.
• To explore associations between ECG findings and clinical/radiological characteristics of ICH.

Main Methods:

• Retrospective review of clinical and radiological data from 118 ICH patients.
• Analysis of ECG recordings obtained within 24 hours of hemorrhage onset.
• Logistic regression analysis to identify independent predictive factors for ECG abnormalities.

Main Results:

• 56% of ICH patients exhibited one or more ECG abnormalities.
• Common abnormalities included ST depression (24%), left ventricular hypertrophy (20%), QTc prolongation (19%), and T wave inversion (19%).
• Insular involvement predicted ST depression and QTc prolongation; intraventricular hemorrhage predicted QTc prolongation; deep hematoma location and larger volume predicted T wave inversion.

Conclusions:

• ECG abnormalities are frequent in ICH.
• Specific radiological findings, such as insular involvement and intraventricular hemorrhage, are associated with particular ECG changes.
• These findings suggest a link between the characteristics of intracerebral hemorrhage and cardiac electrical alterations.
