[Atrio-ventricular and intra-ventricular conduction disorders in a case of acute cerebrovascular disease]
Insights
This study observed transient heart rhythm disturbances, including atrioventricular and intraventricular blocks, in a patient with acute cerebral thrombosis. These ECG changes were likely due to autonomic nervous system imbalance, reduced cardiac output, or conduction tissue damage.
Area of Science:
- Cardiology
- Neurology
- Electrophysiology
Context:
- A 67-year-old male patient presented with acute cerebral thrombosis.
- The patient exhibited transient electrocardiogram (ECG) abnormalities.
Purpose:
- To investigate the causes of transient cardiac conduction disturbances in the context of acute cerebral thrombosis.
Summary:
- Transient atrioventricular block (1st-degree and 2nd-degree type II), coronary sinus rhythm, dissociation, and intraventricular block (left anterior hemiblock) were observed.
- Potential contributing factors identified include neurovegetative dysregulation (vagal hypertonus), impaired conduction tissue circulation from decreased cardiac output, and histological damage to specific cardiac tissues.
Impact:
- Highlights the complex interplay between neurological events and cardiac function.
- Suggests potential mechanisms for ECG abnormalities in stroke patients.
- Emphasizes the importance of comprehensive cardiac evaluation in neurological emergencies.
Abstract:
Transient atrioventricular (1st-degree and 2nd-degree (type II) block, coronary node rhythm, dissociation) and intraventricular (left anterior hemiblock) disturbance were noted in a 67-yr-old man with acute cerebral thrombosis. It is suggested that one of more of the following factors were responsible from time to time for these unusual ECG signs: disturbance of neurovegetative regulation with predominant vagal hypertonus, circulation deficiencies in the conduction tissue due to decreased cardiac output, and histological lesion of specific tissue.
