Key result
Systolic pressure in the right ventricle correlates with the height of R waves in the right precordial leads of the electrocardiogram in patients with pulmonary stenosis.
Why the study?
Does the electrocardiogram correlate with systolic pressure in the right ventricle in patients with pulmonary stenosis?
Observational
Does the electrocardiogram correlate with systolic pressure in the right ventricle in patients with pulmonary stenosis?
This paper examines the relationship between right ventricular systolic pressure and electrocardiogram findings in patients with pulmonary stenosis.
May support noninvasive RV pressure estimation via ECG in pulmonary stenosis; leaves open validation and clinical utility in contemporary cohorts.
PULMONARY stenosis with intact ventricular septum raises the systolic pressure in the right ventricle and may lead to cardiac failure. Consequently, all severe lesions of this type, even if unaccompanied by symptoms, require surgical correction. The only accurate method for determining the degree of hypertension is catheterization of the right side of the heart. A previous study from this department1 reported a rather close correlation between the level of systolic pressure in the right ventricle, as recorded at cardiac catheterization, and the height of the R waves in the right precordial leads of the electrocardiogram in patients with pulmonary stenosis . . .

Cayler et al. (1958) conducted an observational in Pulmonary stenosis. Systolic pressure in the right ventricle was evaluated on Correlation between right ventricular systolic pressure and R wave height in right precordial leads. Systolic pressure in the right ventricle correlates with the height of R waves in the right precordial leads of the electrocardiogram in patients with pulmonary stenosis.
