Запорожская медицинская академия последипломного образования Министерства здравоохранения Украины, Запорожье, Украина Prospects for assessment of heart rate turbulence as a predictor of fatal arrhythmias in patients after acute myocardial infarction Перспективы оценки турбулентности сердечного ритма как предиктора фатальных аритмий у пациентов после острого инфаркта миокарда ______________________ Abstract __________________________________________________________________________ Over the past 20 years, cardiovascular mortality has decreased in developed countries, as there were taken the preventive measures to reduce the prevalence of the coronary heart disease (CHD). <...> Despite these encouraging results, cardiovascular disease is the leading cause of death of approximately 17 million people per year worldwide. <...> One of the new, non-invasive, advanced methods of prognosis of sudden death in patients with CHD with ventricular arrhythmias after myocardial infarction may be an assessment of heart rate turbulence. <...> The heart rhythm turbulence (HRT) is a change in heart rate that is developed in response to emerging ventricular arrhythmias and manifested in short-term fl uctuations of the heart rate. <...> Ключевые слова: ишемическая болезнь сердца, желудочковая экстрасистолия, турбулентность сердечного ритма, внезапная кардиальная смерть, острый инфаркт миокарда. _________________________________________________________________________________________________ «Кардиология в Беларуси» 2016, том 8, № 2 237 Перспективы оценки турбулентности сердечного ритма как предиктора фатальных аритмий у пациентов после острого инфаркта миокарда Over the past 20 years, cardiovascular mortality has decreased in developed countries, as there were taken the preventive measures to reduce the prevalence of the coronary heart disease (CHD). <...> Despite these encouraging results, cardiovascular disease is the leading cause of death of approximately 17 million people per year worldwide [1, 2]. <...> In CHD patients with acute myocardial infarction, the ventricular arrhythmias may be an important prognostic factor. <...> The spectrum of ventricular arrhythmias can range from asymptomatic individual premature ventricular contractions to those, which create serious symptoms of fatal arrhythmias. <...> The prognostic value of premature ventricular contraction (PVC) currently remains poorly studied. <...> Thus, according to a recently published meta-analysis, in patients without structural heart disease in the presence of frequent premature ventricular contraction, an increase of the risk of cardiovascular complications was observed [4]. <...> The role of frequent premature ventricular <...>
