A defibrillator (1), which selectively delivers a defibrillation pulse to a patient (2), includes electrodes (22, 24) adapted for placement on the patient, a monitoring circuit (4) for providing an electrocardiogram (ECG) of the patient (2), and a defibrillation pulse generator (12) having an energy store (8). A switch (6) in electrical communication with the ECG monitoring circuit (4) and the defibrillation pulse generator (12) selectively electrically connects the monitoring circuit (4) and the defibrillation pulse generator (12) to the electrodes (22, 24). A microprocessor (18) is in electrical communication with the monitoring circuit (4), the defibrillation pulse generator (12), and the switch (6). The microprocessor (18) causes the switch (6) to electrically connect the monitoring circuit (4) to the electrodes (22, 24) in order to provide the ECG of the patient (2). The microprocessor (18) also determines a scaling exponent for the patient from the ECG. The microprocessor further compares the scaling exponent to a predetermined value and selectively causes the switch (6) to electrically connect the defibrillation pulse generator (12) to the electrodes (22, 24) in order that the energy store (8) delivers the defibrillation pulse to the patient (2). |
