sorry, I forgot. And no leaks between left and right chambers (=shunts).
A structurally normal heart:
- No pathological leaks on valves (they all leak a little, because they close when blood pushes back)
- No hypertrophy (thicker walls), atrial or ventricular
- No dilation (thinner walls due to enlarged heart), atrial or ventricular
- Normal contractility (ejects between 50 and 75% of it's blood volume in each beat)
- No scars or non-functioning areas due to heart attacks.
- No signs of myocarditis, endocarditis, pericarditis (heart inflammation)
= structurally normal :)
Simple answer......what you can feel to the touch.....in other words that your heart physically is within normal limits of the perimeter of the heart in statistics....a very good thing....................................................
That is a complicated question, but for a starter I'd say it means all the chambers, walls and valves have normal size, thickness, and operation (respectively). I think it does not mean one can not have electrical/rhythm problems, that is different that structurally normal.
