<p>A defibrillation circuit (30, 40) generates a defibrillation pulse (Tp, Th) and includes a patient?parameter compensator (34, 42) that causes the pulse (Tp, Th) to have a predetermined characteristic regardless of the value of a patient parameter (Rp). For example, the circuit (30, 40) can generate defibrillation pulses (Tp, Th) that have a desired shape, decay rate, voltage level, current level, and/or energy level regardless of the patient impedance (Rp). Consequently, a defibrillator (50) that includes the circuit (30, 40) is likely to be more effective than prior defibrillators in restoring normal heart rhythms to patients having an atypical value for a parameter such as impedance (Rp, Th).</p> |
