1. A dynamic heart rate monitor comprising:

  • a neckband, said neckband having a smoothly arched profile for hanging on the user'"'"'s neck;

    a first electrode set carried in said neckband for disposing on the skin of the user'"'"'s neck;

    a heart rate recording and display unit, said heart rate recording and display unit comprising a casing, a LCD (Liquid Crystal Display) mounted in an outside wall of said casing, a piezoelectric detection circuit mounted inside said casing, and a USB (Universal Serial Bus) connector electrically coupled to said piezoelectric detection circuit and extended out of said casing;

    a first pair of electric wires respectively electrically coupled to said first electrode and respectively extending out of two distal ends of said neckband and respectively electrically coupled to said heart rate recording and display unit;

    a second electrode set, said second electrode set comprising a left electrically conductive rubber vacuum mount and a right electrically conductive rubber vacuum mount respectively attachable to left and right sides of the user'"'"'s chest by means of a vacuum suction force;

    a second pair of electric wires that couple said left and right electrically conductive rubber vacuum mounts to said heart rate recording and display unit;

    wherein said first electrode set and said second electrode set measure the heart rate of the user to provide a voltage signal to said piezoelectric detection circuit of said heart rate recording and display unit for processing;

    said piezoelectric detection circuit of said heart rate recording and display unit comprises a series of inductances adapted to filter the voltage signal received from said first and second electrode sets through said first and second pairs of electric wires, a filter rectifier circuit electrically coupled to said series of inductances and adapted to rectify the waveform of the filtered heart rate voltage signal from said series of inductances, a CPU (Central Processing Unit) electrically coupled to said filter rectifier and adapted to process said heart rate voltage signal into a heart rate data signal and to amplify the heart rate data signal through an amplifier thereof for enabling the amplified heart rate data signal to be sent to said LCD for display and sent to an external computer through said USB connector for storage and analysis.
