ARRITMIAS CARDÍACAS EM GESTANTES
As arritmias cardíacas são patologias que alteram os ritmos dos batimentos cardíacos, elevando-os ou diminuindo-os, essas alterações podem gerar diversos danos, e, quando ocorrem no período gestacional necessita-se de cuidados adicionais, pois, podem acarretar prejuízos a saúde da gestante e do feto.
