Simultaneous arterial (A) and left ventricular (LV) pressures were recorded in a patient with hypertrophic obstructive cardiomyopathy. The first three beats show a peak systolic gradient of 25 mm Hg. On the first sinus beat after a premature ventricular contraction (PVC), the peak-systolic gradient increases to over 100 mm Hg, but the pulse pressure (arterial systolic pressure minus diastolic pressure) decreases. This characteristic pattern is known as the Brockenbrough-Braunwald sign. The decrease in pulse pressure after a premature ventricular contraction is due to reduced stroke volume caused by increased dynamic obstruction, which is . . . [Full Text of this Article]
