Key result
Late potentials were absent in patients without organic heart disease, but frequently found in those with dilated cardiomyopathy, old myocardial infarction, and ventricular aneurysm.
Why the study?
Does the recognition of late potentials differ among patients with various organic heart diseases and ventricular arrhythmias?
Observational
Does the recognition of late potentials differ among patients with various organic heart diseases and ventricular arrhythmias?
The clinical value of late potentials for assessing ventricular arrhythmias depends heavily on the underlying type of organic heart disease.
No takes yet. Share an insight, caveat, or question.
Late potentials' presence varies by heart disease type; supports disease-specific interpretation but leaves open prognostic utility.
Ozawa et al. (1987) conducted an observational in Ventricular arrhythmias and organic heart diseases. Evaluation of late potentials was evaluated on Recognition of late potentials. Late potentials were absent in patients without organic heart disease, but frequently found in those with dilated cardiomyopathy, old myocardial infarction, and ventricular aneurysm.
