Ambulatory physiological evaluation system including cardiac monitoring
First Claim
1. A vest for use in an ambulatory physiological evaluation system, said vest comprising:
- a flexible, planar vest member to be worn about the torso of a patient, said member including an enlarged chest area that covers the chest of the wearer, a pair of strips disposed on opposite sides of said chest area, each of said strips passing below one of the arms of the patient and lying against the back of the patient;
fist securing means at the end of each strip for joining the strips to arrange said member about the torso in a snug fit so that the member remains relatively stationary relative to the torso during movement of the patient;
a pair of planar elongated straps, each of said straps spanning across one of the shoulders of said patient, one end of each strap terminating in means for movably mounted said strap to said chest area, the other end of each strap terminating in means for securing said strap to one of said strips of said vest member;
quick release means dividing the vest top to bottom in a first area of the vest for covering the right side of a wearer'"'"'s chest; and
mounting means on a second area of the vest for apparatus to be used in said evaluation system, said mounting means being located on a second area of the vest for covering a left part of the wearer'"'"'s chest.

Abstract
An ambulatory physiological evaluation system including a main and a background gamma radiation detector provided in a vestlike garment worn by a patient for the purpose of monitoring and/or diagnosing the patient'"'"'s physiological activities during a prescribed period of time. Also included is an apparatus and method for determining the exact location of the left ventricle of the heart, positioning the main radiation detector relative to the left ventricle, and maintaining the position of the main radiation detector relative to the left ventricle during an ambulatory study period. The ambulatory physiological evaluation system also contains electronic circuitry which monitors and processes information obtained from the radiation detectors. Information from the main and auxiliary detectors, as well as ECG electrodes is recorded on a portable cassette recorder. After the information has been recorded over a desired period of time, the information is presented, through an interface and an analog to digital converter, to the memory of a stand alone computer located in a hospital or office. The computer calculates such items as R-R time intervals, electrocardiagram and time-activity curves, and displays these items and other physiological data for both the main and auxiliary detectors. From the calculations made by the computer, average heart rate, number of aberrant beats, left ventricular ejection fraction and relative cardiac blood volume and other values of physiological significance may be calculated for a time interval of interest.

6. A vest for use in an ambulatory physiological evaluatory system comprising:
-
a flexible chest member adapted to be worn about the body of a patient to cover the upper torso including the chest of the patient with end portions extending under the arms and around the patient'"'"'s back; adjustable shoulder strap means adapted to span the patient'"'"'s shoulders extending from front to back portions of the vest; adjustable connector means between the opposite end portions of the vest; quick-release tear-away means dividing the chest member top to bottom on the right side of the patient'"'"'s chest into opposed sections; securement means for holding the respective sections together; and attachment means on the left side of the chest member for positioning a heart detector on the vest to monitor the patient'"'"'s heart function. - View Dependent Claims (7, 8)

9. A vest for use in an ambulatory physiological evaluation system, said vest having mounting means for apparatus to be used in said system and comprising:
-
a flexible, planar vest member to be worn about the torso of a patient, said member including an enlarged chest area that covers the chest of the wearer, a pair of strip areas integrally formed with and disposed on opposite sides of said chest area, each of said strip areas passing below one of the arms of the patient, terminating in a free end lying against the back of the patient, said free ends lying in spaced relation; first securing means extending from the free end of each strip area toward the free end of the other strip area for joining the strip areas; second securing means at each free end of said strip area for cooperating with the first securing means extending from the free end of the other strip area to arrange said member about the torso in a snug fit so that the member remains stationary relative to the torso during movement of the patient; a pair of planar elongated straps, each of said strips spanning across one of the shoulders of said patient, one end of each strap terminating in means for removably mounting said strap to said chest area, the other end of said strap terminating in means for securing said strap to the back of said vest member; and quick release means along a side area of said member, said release means defined by overlapping portions of said side area and a series of coacting fasteners distributed lengthwise along a line extending from the top of the overlapping portions of the side area of the member to the bottom of the overlapping portions of the side area of the member.
