Typical bedside findings of chronic tricuspid regurgitation include increased jugular venous mean pressure, with a small "a" wave and a large "cv;" a right ventricular systolic impulse, due to right ventricular dilation; a high frequency, holosystolic murmur at the lower left sternal edge, due to tricuspid regurgitation; a third heart sound and a mid diastolic murmur, due to enhanced right ventricular filling. All these acoustic events increase in intensity with inspiration.
