Key result
High-frequency components in the electrocardiogram were similarly elevated in patients with ventricular enlargement and those with infarction, clearly distinguishing both groups from normal subjects.
Why the study?
Does the presence of high-frequency components in the electrocardiogram correlate with anatomic findings of ventricular enlargement or infarction?
Observational (n=128)
Does the presence of high-frequency components in the electrocardiogram correlate with anatomic findings of ventricular enlargement or infarction?
High-frequency components in the ECG may reflect competing generator sites of ventricular enlargement as well as the classic concept of shattering of the wave of activation from infarction.
No takes yet. Share an insight, caveat, or question.
High-frequency ECG components may flag ventricular enlargement or infarction; leaves open diagnostic specificity and prospective validation.
Flowers et al. (1969) conducted an observational in Ventricular enlargement and myocardial infarction (n=128). High-frequency components in the electrocardiogram vs. Normal subjects was evaluated on Number of high-frequency components (notching and slurring of the expanded QRS). High-frequency components in the electrocardiogram were similarly elevated in patients with ventricular enlargement and those with infarction, clearly distinguishing both groups from normal subjects.
