No evidence of dynamic outflow tract obstruction (no change in murmur intensity with Valsalva). Carotid upstroke is normal. Peripheral pulses are symmetric, no peripheral edema. Lungs are clear to auscultation bilaterally.

Treatment Protocol

Continue current regimen of [Beta-blocker/Calcium channel blocker] for symptom management and heart rate control. Maintain strict hydration and avoid volume depletion. Avoid high-intensity competitive sports. Schedule annual transthoracic echocardiogram (TTE) and Holter monitoring for arrhythmia surveillance. Discussed importance of family screening and genetic counseling.
