Prognostic significance of electrocardiographic voltages and their serial changes in elderly with systolic hypertension.
The aim of the present study was to assess the prognostic value of ECG voltages at baseline and their serial changes during follow-up in a large prospective study with standardized follow-up and strictly defined end points. Patients who were 60 years old or older, with systolic blood pressure of 160 to 219 mm Hg and diastolic pressure <95 mm Hg, were randomized into the double-blind placebo-con...
متن کاملElectrocardiographic Parameters of Ventricular Repolarization – Modifiers and the Prognostic Value
Normal electric activity of the heart consists of repeated cardiomyocyte depolarizations and repolarizations. Repolarization of the ventricular action potential is dependent on both inward and outward ion fluxes across cell membranes. Repolarization abnormalities may predispose to ventricular arrhythmias, and several factors may modify repolarization-related arrhythmia vulnerability. Ventricula...
متن کاملSignificance of electrocardiographic changes in hypertension.
Studies in 17 hypertensive patients showed that the electrocardiographic features of T-wave inversion and S-T segment depression distinguish those patients with higher systolic blood pressures. They do not indicate impaired cardiac function.
متن کاملPrognostic implications of baseline electrocardiographic features and their serial changes in subjects with left ventricular hypertrophy.
BACKGROUND During the past half-century, the ECG has been used extensively for the diagnosis of left ventricular hypertrophy. Persons with ECG evidence of left ventricular hypertrophy are at increased risk for the development of cardiovascular disease. METHODS AND RESULTS Subjects from the Framingham Heart Study with ECG evidence of left ventricular hypertrophy were eligible for this investig...
متن کاملElectrocardiographic Early Repolarization
1520 The early repolarization (ER) pattern (ERP), initially described as elevation of the ST segment of ≥1 leads on the 12-lead ECG, has long been considered a benign phenomenon. However, more recent studies have demonstrated positive, negative, and neutral associations between an ERP and various end points, including all-cause, cardiac, and arrhythmic mortality. These recent studies have used ...
