A halin yanzu ana amfani da na'urar ceto zuciya (cardiac defibrillator) wajen aikin ceto asibiti. Yana amfani da na'urar bugun zuciya (pulsed current) don yin aiki a kan zuciya, aiwatar da maganin girgizar lantarki, kawar da bugun zuciya (arrhythmia), da kuma dawo da yanayin zuciya zuwa yanayin sinus..
Ka'idar aikinsa galibi tana amfani da hanyar fitar da damping na RLC, kamar yadda aka nuna a cikin hoton:
