[en] Nowadays, early defibrillation is the most efficient therapy to improve survival of victims of cardiac arrest caused by fibrillating rhythms. The automated external defibrillator (AED) was developed by the medical industry, to be placed in strategic locations so that laypersons with minimal training would be able to promptly help victims of cardiac arrest. The AED is a health device that analyzes the patient's electrocardiogram (ECG) and has the ability to detect ventricular fibrillation (VF) and ventricular tachycardia (VT), which are lethal ventricular rhythms; it is a device that digitally processes the patient's' ECG. In emergency services, cardiopulmonary resuscitation (CPR) and early defibrillation are the two fundamental actions. The chest-compressions during CPR are essential, however, they create interferences in the ECG. Besides that, in an emergency situation experts and non-experts do their work in a whirlwind of stress and prompt care, with high nervousness and with little time to make a diagnosis. The aim of this work is, to create a software management platform that using the annotations of three different doctors (as recommended by the American Heart Association – AHA) helps analyzing and studying one by one the patients' registers, which consist of the ECG and impedance (TTI, Thransthoratic impedance) signals; in that way, we contribute to the development of a method that improves the difficulties that existing AED's have to detect defibrillable rhythms and to improve the care of hospitals' and emergency services, in order to increase the survival of cardiac arrest victims.

[eu] Desfibrilazio goiztiarra erritmo fibrilagarrien ondorioz bihotza gelditzen zaien biktimen biziraupenerako kontrolik eraginkorrena da gaur egun. Medikuntza industriak kanpoko desfibrigailu automatikoa (KDA) garatu zuen, hauek leku publiko estrategikoetan kokatzeko, eta gutxienezko entrenamendua duten pertsonek bihotz-biriketako gelditzea jasaten duten biktimak berehala lagundu ahal izateko. KDA-ak pazientearen elektrokardiograma (EKG) aztertu eta fibrilazio bentrikularra (FB) zein takikardia bentrikularra (TB), hots, bentrikulu-erritmo hilgarriak, detektatzeko gaitasuna duen osasun gailua da, pazienteen EKG-a digitalki prozesatzen duen gailua alegia. Larrialdi zerbitzuetarako oinarrizko bi ekintzak bihotz-biriketako berpiztea (BBB) eta dagoeneko aipatutako desfibrilazio goiztiarra dira. Beharrezkoak diren BBB-aren bular-sakadek, ordea, interferentziak sortzen dituzte EKG-an. Horrez gain, larrialdi egoera hauen aurrean adituak diren zein ez direnek tentsio handi eta berehalako arreta baten menpe lan egin behar dute, urduritasun handia izanik eta diagnosiak egiteko denbora handirik izan gabe. Hori dela eta, lan honek duen helburu nagusia EKG eta baita inpedantzia (TTI, Thransthoratic impedance) seinaleetan oinarriturik paziente ezberdinen erregistroak bananbanan aztertzen eta analizatzen laguntzen duen software kudeaketa plataforma bat eratzea da, American Heart Association-ek (AHA) gomendaturik hiru mediku ezberdinen anotazioak kontuan harturik ere; horrela, gaur egungo KDA-ek desfibrilazioak hautemateko dituzten zailtasunak hobetzen duen metodoa aurkitzeko ikerketa sustatu nahi da eta ospitaleetako eta larrialdi zerbitzuetako arreta are gehiago hobetu, bihotz-biriketako gelditzea jasaten duten biktimen biziraupena handituz.
