[en] Arrhythmias are known as irregularities that happen in the cardiac conduction system. These heart rate variations can occur when the heart rate is accelerated or decreased, and they do not necessarily have to be irregular. However, arrhythmias usually create irregular rhythms when abnormalities occur in the physiological pacemaker of the heart or in the electrical system of the heart. There are several types of arrhythmias, some of the most typical ones are those occurring in the atria. A patient suffers atrial fibrillation (AF) when the beats that occur in those cavities are disorganized. AF is the most common arrhythmia, as well as being the one that causes most expenses in the health system. In fact, in the last decade the prevalence of this arrhythmia has been increasing, and it is expected that it will get worse due to the aging of the population. AF is not one of the most serious arrhythmias, since it doesn ́t put human lives at risk. However, it is very detrimental for the patient ́s health, since people suffering from this disease could have a high risk of morbidity in case of suffering heart failure or an embolism. Thus, we can conclude that it is very important to find methods that predict AF. Therefore, that ́s what is going to be developed in this project. To obtain this goal, we will take some information of certain patients which, as it will be explained later, is basedon records called electrocardiograms. Therefore, after processing this information, different algorithms will be developed to predict AF. Finally, the results obtained from these algorithms will be analyzed, which will help us to conclude if these methods are reliable or not.

[eu] Bihotzeko arritmiak bihotzaren funtzio elektrikoan gertatzen diren irregulartasunak dira.Bihotzeko erritmoaren aldaketa hauek, erritmoa bizkortzeagatik ala gutxiagotzeagatik izan daitezke, eta ez dira nahitaez irregularrak izan behar. Hala ere, normalean arritmiek erritmo irregularra sortzen dute, bihotzaren berezko taupadan edota bihotzaren sistema elektrikoan anomaliak agertzen direnean. Zenbait arritmia mota aurki daitezke; horien artean, aurikuletan agertzen dena bereiz daiteke. Kasu honetan, aurikuletan ematen diren taupadak desorekatuak direnean fibrilazio aurikularra (FA) agertu dela esaten da. FA bihotz-arritmiarik ohikoena dela esan ohi da, baita osasun sisteman kosturik handiena eragiten duena ere. Izan ere, azkeneko hamarkadan FA ren prebalentzia handituz joan da, eta okerrera jarraituko du gizartearen zahartzearen ondorioz. FA ez da arritmien artean larriena, arritmia mota honek ez baitu berez gizakiaren bizitza arriskuan ipintzen. Hala ere, oso kaltegarria da bizitzarako. Izan ere, arritmia honek pertsona batengan bihotz-gutxiegitasunagatik edo enbolia batengatik morbilitate arrisku altua izatea eragin ditzake. Hau guztia dela eta, FA aurresateko metodoak izatea oso garrantzitsua dela ondoriozta dezakegu. Hori izango da, beraz, proiektu honetan zehar garatuko dena. Horretarako, zenbait pazienteren informazioaz baliatuko da, geroago azalduko den moduan, informazio hori elektrokardiograma deituriko erregistroetan oinarrituta egongo da. Beraz, erregistro horiek abiapuntutzat edukita, eta informazio jakin hori prozesatu eta landu ondoren, FA aurresateko zenbait algoritmo garatuko dira. Azkenik, garatutako algoritmo horiekin lortutako emaitzak aztertuko dira, metodo hauek fidagarriak diren ala ez ondorioztatzeko.
