  • Publication number: 20040236378
    Abstract: In a cardiac pacemaker arrangement comprising an electrode arranged floatingly in the atrium, a circuit for perceiving atrial signals, and a circuit for stimulating the atrial myocardium by means of the electrode, the invention proposes that in addition there is provided a wall-located electrode, and stimulation is effected by means of the wall-located electrode if the circuit, upon perceiving atrial signals, does not detect high-frequency irregularities—such as auricular fibrillation or atrial tachycardias—as on the basis of inadmissibly high signal frequencies—, and stimulation is effected by means of the floating electrode if the circuit, upon perceiving atrial signals, detects irregularities of that kind. This permits early detection and termination of atrial tachycardias and auricular fibrillation.

  • Publication number: 20040059390
    Abstract: An arrangement for treating rhythm disturbances of a heart (H), especially tachycardia and fibrillation, has a device (FD) for detecting the heart rhythm and determining when a fibrillation threshold limit is exceeded and a therapy device or stimulator (IG). The therapy device (IG) is connected to the heart rhythm detecting device (FD), to begin to treat the fibrillation when the fibrillation threshold limit is exceeded. The heart rhythm detecting device determines whether a redetection threshold limit is still exceeded after the therapy device has treated the fibrillation, the redetection threshold limit being lower than the fibrillation threshold limit and higher than a tachycardia threshold limit. The therapy device continues to treat the fibrillation as long as the heart rhythm detector determines that the redection threshold limit is exceeded.
