1. A skin electrode assembly comprising:
- a front fabric panel having a plurality of apertures each in a predetermined pattern with respect to said other apertures for placement over the chest of the patient;
a plurality of electrodes each associated with a respective one of said apertures; and
each of said electrodes including(a) a shaft at least partially within a respective aperture on said front panel and having a shaft axis;
(b) an electrode tip affixed to one end of said shaft for engagement with the skin of the patient;
(c) said shaft movable within said aperture and with respect to said front panel in a direction along said shaft axis;
(d) a stop at the other end of said shaft securing said shaft and electrode tip to said panel;
(e) biasing means adjacent said shaft between said front panel and said electrode tip for biasing said electrode tip into engagement with the skin of the patient;
(f) a ring-shaped member generally encompassing said shaft and having a contact surface for limiting axial movement of said electrode tip to a predetermined extent;
(g) said electrode tip movable outwardly by said biasing means from said fabric panel beyond said contact surface;
(h) an electrode connector electrically connected to said ring-shaped member; and
(i) said ring-shaped member is conductive for transmitting signals from the skin to the electrode connector.

Abstract
A vest-like garment is provided comprising a front fabric panel with a plurality of apertures adapted for receiving associated electrodes, a horizontally stretchable rear panel, and a pair of vertically stretchable shoulder straps. Each of the electrodes is biased against the front panel for better electrical engagement with the skin of the user. Leads from each electrode may carry signals to a telephonic transmission unit, which is also equipped with emergency electrode handles.
