Electrocardiographic Predictors of Cardiovascular Mortality

Abstract

Cardiovascular diseases are the main causes of mortality. Sudden cardiac death may also appear in athletes, due to underlying congenital or inherited cardiac abnormalities. The electrocardiogram is used in clinical practice and clinical trials, as a valid, reliable, accessible, inexpensive method. The aim of the present paper was to review electrocardiographic (ECG) signs associated with cardiovascular mortality and the mechanisms underlying those associations, providing a brief description of the main studies in this area, and consider their implication for clinical practice in the general population and athletes. The main ECG parameters associated with cardiovascular mortality in the present paper are the P wave (duration, interatrial block, and deep terminal negativity of the P wave in V1), prolonged QT and Tpeak-Tend intervals, QRS duration and fragmentation, bundle branch block, ST segment depression and elevation, T waves (inverted, T wave axes), spatial angles between QRS and T vectors, premature ventricular contractions, and ECG hypertrophy criteria.

Cardiovascular morbidity and dyslipidemia in chronic kidney disease: a cross-sectional study

“…8,9 The study identified ECG and ECHO changes (Table 3) in considerable number of patients among whom left ventricular hypertrophy/dilatation followed by right sided heart dilatation which was clear manifestation of excess fluid overload and peripheral vascular resistance due to improper fluid excretion in CKD. In the ECG study by Mozos et al in 2015 and Shafi et al 10,11 recently in 2017, similar results were recorded as changes in CKD patients. These changes cannot be earmarked as specific for CKD but can be used as markers in predicting CVD severity or prognosis in CKD which is a scope for future research.…”

The Prevalence of Electrocardiographic Indicators Among Men and Women of Older Ages in the Russian Federation

“…Полученные результаты близки к эпидемиологиче-ским данным, представленным бельгийскими автора-ми, которые показали, что частота выраженных изме-нений ST у мужчин и женщин составляет 1,6% и 2,7%, а аномальных зубцов Т -6,1% и 9,6%, соответствен-но [8]. Частота ишемических кодов в популяции Но-восибирска и Тюмени также была схожа с нашими дан-ными -6,8% и 5,1%, соответственно [4].…”

“…Значения распространенности НП, полученные нами на выборках ЭССЕ-РФ для старшего возрастного кон-тингента, оказываются выше, чем в других странах (0,8% у женщин и 1,8% у мужчин) [8,11] и чем у исследо-вателей SAHR (0,5% и 1,1%, соответственно) [6]. Воз-можно, это связано с более выраженным бременем ССЗ в регионах РФ и меньшей возможностью получения адекватной помощи.…”

Remote monitoring of cardiac activity using a flexible loop antenna

“…Indeed, applying medical sensors has demonstrated a remarkable efficiency in treating multiple diseases such as retinal, gastric, and heart‐related diseases . Worth noting, in this respect, is that heart‐associated diseases turn out to stand as the major cause of death worldwide …”
