Pulse rate monitor
First Claim
1. A heart monitor comprising:
- a housing adapted to be worn on a person;
a display of heart-beat data supported by said housing, said display including indicators of duration of interpulse intervals between successive beats of the heart, and counts of heart beats occurring within predetermined ranges of interpulse intervals;
the indicators of duration of interpulse intervals being located at sites corresponding to sites of the locations of the indicators of the counts of the heart beats to show symmetric and skewed distribution of interpulse intervals; and
electronic circuitry enclosed within said housing and responsive to heart beats of said person for driving said indicators, said circuitry including a detector of heart beats, means coupled to said detector for counting heart beats, means coupled to said counting means for designating a sequence of measurement intervals, and means coupled to said designating means for measuring the duration of interpulse intervals and the number of beats occurring in each of said ranges, said measuring means being coupled to said indicators.

Abstract
A heart monitor is constructed with a housing that is to be worn by a person, the housing including a display of heartbeat data and a detector of pulsations of the heart. The interpulse intervals between successive pulses, or heart beats, are measured to provide heart-beat data which includes the frequency of occurrence of various ranges of interpulse intervals, as well as an average value of interpulse intervals. The display positions the average value in registration with a corresponding range of the frequency of occurrence. The average value is measured by counting pulses through a succession of interpulse intervals. The frequency of occurrence is measured by a set of sequentially activated gating circuits with counters coupled thereto for counting the occurrences of interpulse intervals of differing durations.

10. An analyzer of pulsation comprising:
-
means for detecting pulses of a sequence of said pulses, said pulses being separated by interpulse intervals; means coupled to said detecting means for measuring an average value of said interpulse intervals; means coupled to said detecting means for measuring the frequency of occurrence of individual ones of said interpulse intervals; and means coupled to said average-value measuring means and to said occurrence measuring means for presenting data of said average value in visual correspondence with data of said frequency of occurrence. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
