  • Apparatus and method for therapy adjustment in implantable
    Patent number: 4895151
    Abstract: Apparatus and method for treating tachyarrhythmias wherein the presence of a patient tachyarrhythmia is detected and a first antitachyarrhythmia therapy (antitachycardia pacing) is given at a first energy level. The haemodynamic condition of the patient is measured and a length of time to therapy switchover is continually derived during the application of the first antitachyarrhythmia therapy. The length of time to switchover is a function of the haemodynamic condition of the patient. When the time following detection of the patient tachyarrhythmia exceeds the length of time to switchover, a second antitachyarrhythmia therapy (a high energy shock) at a second energy level is provided. The average cardiac cycle length may be used as an indicator of the haemodynamic condition.
