1. A method performed by a defibrillator, the method comprising:
outputting an instruction to perform chest compressions on a patient during a time period extending from a first time to a second time;
identifying physiological parameter data corresponding to a physiological parameter of the patient detected after the first time and before the second time;
generating filtered physiological parameter data by removing, from the physiological parameter data, an artifact associated with the chest compressions using a comb filter, wherein a Q of the comb filter is greater than 4;
determining, based on the filtered physiological parameter data, that a heart rhythm of the patient is shockable; and
in response to determining that the heart rhythm is shockable, charging an energy storage module before the second time.
