You are incorrect - our patient's precordial movement at the apex is best described as non displaced and sustained systolic.
Your choice: Non displaced, sustained systolic, presystolic
This apical impulse is non displaced and sustained systolic with a presystolic component. A sustained apical impulse with a presystolic component might be felt in a patient with left ventricular hypertrophy. A presystolic impulse is the palpable equivalent of an audible fourth heart sound. In the video, note the presystolic component occurs just before the carotid pulse and the sustained impulse occurs with the carotid pulse.
