  • Arrangement for determining a heart rate automatically establishing the optimal refractory time for heart rate determination
    Patent number: 6064907
    Abstract: An arrangement for determining the heart rate (f.sub.RR) or the refractory ime of the cardiac tissue, particularly for detecting tachycardia or fibrillation, has an electrode (E) for sensing heart action signals (SIG), an input stage, connected to the electrode, for processing the heart action signals, a refractory member for ascertaining a refractory time value of the arrangement, in each case after a predetermined segment of a heart action signal, and a processing device, connected to the output of the input stage or of the refractory member, for determining the rate of the heart action signals, processed with blanking of the component that occurs during the refractory time, or for determining the refractory time value of the cardiac tissue.
    Type: Grant

    Date of Patent: May 16, 2000
    Assignee: BIOTRONIK Mess--und Therapiegeraete GmbH & Co. Ingenieurbuero Berlin
    Inventors: Tran Thong, Paul Wyborny, Dennis Digby, Nawzer Mehta, Max Schaldach
  • Arrangement for determining a heart rate by automatically establishing the optimal refractory time for heart rate determination
    Patent number: RE38680
    Abstract: An arrangement for determining the heart rate (fRR) or the refractory time of the cardiac tissue, particularly for detecting tachycardia or fibrillation, has an electrode (E) for sensing heart action signals (SIG), an input stage, connected to the electrode, for processing the heart action signals, a refractory member for ascertaining a refractory time value of the arrangement, in each case after a predetermined segment of a heart action signal, and a processing device, connected to the output of the input stage or of the refractory member, for determining the rate of the heart action signals, processed with blanking of the component that occurs during the refractory time, or for determining the refractory time value of the cardiac tissue.
