|March 1, 1975
Summary
Electrocardiogram (ECG) studies reveal that a rightward shift in the mean QRS vector axis indicates a poor prognosis in severe kwashiorkor. Conversely, a leftward shift suggests recovery, offering a potential prognostic tool.
Area of Science:
- Cardiology
- Pediatrics
- Nutritional Science
Background:
- Kwashiorkor is a severe form of malnutrition with significant cardiac implications.
- Previous research indicates cardiac dysfunction in severe malnutrition, but prognostic markers are limited.
Purpose of the Study:
- To investigate the prognostic value of electrocardiogram (ECG) findings in severe kwashiorkor.
- To determine if changes in the mean QRS vector axis correlate with patient outcomes.
Main Methods:
- Serial ECG recordings were performed on 32 children with severe kwashiorkor and 2 with marasmus.
- ECG data from 10 healthy controls were used for comparison.
- Analysis focused on the shift of the mean QRS vector axis in limb leads.
Main Results:
- A significant rightward shift in the mean QRS vector axis was observed in patients with a poor prognosis, including those who died.
- Patients without deterioration showed no significant axis shift.
- Deteriorating patients who recovered exhibited a leftward axis shift during their recovery phase.
- No such axis shift was noted in the marasmus cases.
Conclusions:
- The shift in the mean QRS vector axis on ECG is a potential indicator of prognosis in severe kwashiorkor.
- This ECG finding may serve as a useful and accurate prognostic guide for clinicians managing severe malnutrition.
