As arritmias cardíacas são irregularidades nos ritmos cardíacos e/ou perturbações na ativação ou batimento normal do miocárdio, em alguns casos, resulta em doenças cardíacas, o que representa sérias ameaças à vida humana. A patologia é caracterizada por ritmo irregular de batimento cardíaco, que pode ser mais acelerado (taquicardia) ou mais lento do que o normal (bradicardia), podendo ocorrer em qualquer idade. A sintomatologia decorrente desta patologia consiste em cansaço, tontura, desmaios, indisposição, e em casos mais graves a morte. O presente estudo consiste em um levantamento bibliográfico de literatura a respeito das arritmias cardíacas, abrangendo suas formas de diagnóstico e tratamento. O diagnóstico das arritmias consiste nas análises dos sintomas e a realização de testes de monitoramento cardíaco específico para arritmias, incluindo eletrocardiograma, monitor de holter, monitor de eventos externo, ecocardiografia e gravador de loop implantável. Após a confirmação do diagnóstico, encaminha-se para o tratamento, sendo este específico para cada tipo de arritmia, de acordo com as necessidades do paciente. Cardiac arrhythmias are irregularities in cardiac rhythms and / or disturbances in the normal activation or beat of the myocardium, in some cases, resulting in heart disease, which represents serious threats to human life. The pathology is characterized by an irregular heartbeat rhythm, which can be faster (tachycardia) or slower than normal (brachycardia), and can occur at any age. The symptoms resulting from this pathology consist of tiredness, dizziness, fainting, indisposition, and in more severe cases, death. The present study consists of a bibliographic survey of the literature on cardiac arrhythmias, covering their forms of diagnosis and treatment. The diagnosis of arrhythmias consists of the analysis of symptoms and the performance of cardiac monitoring tests specific for arrhythmias, including electrocardiogram, holter monitor, external event monitor, echocardiography and implantable loop recorder. After confirming the diagnosis, the patient is referred for treatment, which is specific to each type of arrhythmia, according to the patient's needs.
