The Precordial Movements in Adults with Pulmonic Stenosis
The precordial movements were studied in 24 adults with pulmonic stenosis. All patients were studied by cardiac catheterization. Normal kinetocardiographic criteria were applied to the patients with pulmonic stenosis. These provided a measure of the magnitude of atrial movements and relative amplitude and duration of movements associated with ventricular systole. Twenty-two patients had abnormal ventricular systolic movements by these criteria. These increased systolic movements are attributed to right ventricular overload. However, the location of these movements was frequently in areas generally considered as reflecting left ventricular activity. Possible explanations for this apparent paradox are discussed. There was a predictable relation between the motions associated with atrial contraction and the right ventricular pressure.
