ABSTRACT:
In an apparatus for measuring the heart wall movement of a person, including a measuring head (10, 12) placeable on the breast with an electrode arrangement (76, 78) and a measuring circuit (84) for capacitively measuring the skin movement with respect to the electrode arrangement (76, 78), the measuring head has a holding ring (10) with an annular surface perpendicular to the ring axis (26) intended for placement on the body (30, 32) and straps for fastening the measuring head (10, 12) to the body. In the holding ring (10) is an adapter (12) including the electrode arrangement (76, 78) resiliently supported for movement in the direction of the ring axis (26) as well as in two other axes perpendicular to the ring axis and to one another. In one exemplary embodiment, the adapter (12) has an annular contact surface (42) intended for placement on a body and an electrode carrier (56) surrounded by the contact surface with a concave electrode carrying surface (74) in the center of which is formed an elevation (80) with at least one electrode (76, 78) being arranged in the annular section of the carrying surface (74) between the contact surface (42) and the elevation (80).
