Respiratory and cardiac abnormalities in brain-stem ischaemia
Journal of Neurology, Neurosurgery, and Psychiatry
|February 1, 1975
Summary
Brain-stem ischemia in two patients caused unusual cardiac arrhythmia and temporary ipsilateral hemidiaphragm elevation. The study discusses potential mechanisms linking these neurological and physiological events.
Area of Science:
- Neurology
- Cardiology
- Physiology
Background:
- Brain-stem ischemia can present with diverse neurological deficits.
- Cardiac and diaphragmatic abnormalities are not typically associated with brain-stem lesions.
Purpose of the Study:
- To present two cases of brain-stem ischemia with unusual associated symptoms.
- To explore the potential mechanisms linking brain-stem lesions to cardiac arrhythmia and diaphragmatic dysfunction.
Main Methods:
- Case report of two patients with brain-stem ischemia.
- Clinical neurological examination.
- Electrocardiographic monitoring.
- Assessment of diaphragmatic function.
Main Results:
- Both patients experienced brain-stem ischemia affecting the pons.
- Neurological signs were accompanied by cardiac arrhythmia (sinus arrhythmia and wandering pacemaker).
- Transient ipsilateral hemidiaphragm elevation was observed in both cases.
Conclusions:
- Brain-stem ischemia can manifest with atypical cardiac and diaphragmatic disturbances.
- The findings suggest a potential neurological pathway influencing cardiac rhythm and diaphragmatic motility.
- Further research is warranted to elucidate the underlying pathophysiological mechanisms.
