Heart activity detection apparatus
First Claim
1. An apparatus for detecting heart activity of an animal heart comprising a housing within which is contained electronic circuitry, a power supply for the circuitry, and an indicator connected to the circuitry and operable by the circuitry to generate an alerting signal detectable by a user, the apparatus further comprising a pair of elongate strips extending in opposite directions from the housing and provided, in the region of a free end of each thereof, with a sensor, the elongate strips being dimensioned such that, when the housing is placed on a person'"'"'s chest, the sensors are positioned at spaced locations on the person'"'"'s chest, the sensors being electrically connected to convey to the circuitry electrical signals detected by the sensors, the circuitry being operative to analyse signals received from the sensors and, upon determination that such signals are electrocardiographic signals received from the sensors and, upon determination that such signals are electrocardiographic signals derived from a heart beat, to cause the indicator to operate so as to generate an alerting signal.

Abstract
Activity of an animal heart is detected with an apparatus comprising a housing (20) within which is contained electronic circuitry (32, 34, 36, 38, 40), a power supply (46) for the circuitry, and an indicator (42, 44) connected to the circuitry which can be operated by the circuitry to generate an alerting signal detectable by a user. In addition there is a pair of sensors (28) electrically connected to convey to the circuitry electrical signals detected by the sensors. The circuitry is operative to analyse signals received from the sensors, and upon determination that such signals are electrocardiographic signals derived from a heart beat to cause the indicator (42, 44) to operate so as to generate an alerting signal.
