Abstract

Disclosed is a system, apparatus and method for gathering physiological data. Basic to the system of the present invention is a rigid body mold having preferably a negative impression of the dorsal half of the body. By connecting and/or embedding sensors to the body mold at specific locations, e.g., accelerometers, thermistors, and electrocardiogram electrodes, the sensors will be accurately and reproducibly positioned next to a specific body location each time the subject lies in the body mold. The body mold can be used to insulate the body from external motions thereby facilitating the preparation of a ballistocardiogram. The exact re-positioning of the body in the mold allows exact determination of the center of gravity in the horizontal plane of the body.

Claims

1. A method for determining a subject'"'"'s heart rate comprising the steps of:

placing the subject'"'"'s body in a supine position in a substantially rigid body mold having an impression intimately matching the entire length of the forsal portion of the subject'"'"'s body and having electrocardiogram electrodes embedded therein to produce an output voltage in response to heart activity, whereby the subject'"'"'s body comes into contact with said electrodes; and

analyzing the electrode output voltage of the electrocardiogram electrodes in order to determine heart rate.

2. A method for determining a subject'"'"'s heart rate comprising the steps of:

placing a body in a supine position in a substantially rigid body mold having an impression intimately matching the entire length of the dorsal portion of the body and having electrocardiogram electrodes embedded therein to produce an output voltage in response to heart activity, by first laying the subject on a thin flexible sheet, and then lowering the sheet bearing the subject into the impression whereby the body of the subject comes into contact with said electrodes through said sheet; and

analyzing the output voltage of the electrocardiogram electrodes in order to determine heart rate.
