Effect of Heart Irregularity on Left Ventricular and Arterial Peak Systolic Pressures in Aortic Stenosis
In aortic stenosis, systemic arterial peak systolic pressure may remain relatively steady in the face of marked, arrhythmia-induced, variations in left ventricular peak systolic pressure. A possible basis for this phenomenon is presented. It is suggested that beat-to-beat variations in the systolic pressure gradient across the aortic valve region may not always reflect variations in stroke volume.
