Echocardiographic Assessment of Right Ventricular Function in Patients With Liver Cirrhosis.

Background: In patients with chronic liver disease, the common endpoint of its course is liver cirrhosis which is a cause of cardiovascular morbidity and mortality. These abnormalities in the cardiovascular system, especially the heart, can be detected by echocardiography. Identifying and acting on these abnormalities can have an impact on their management thereby reducing morbidity and mortality of patients with liver cirrhosis.

QT dispersion in adult hypertensives.

Increased QT dispersion is associated with sudden cardiac death in congestive cardiac failure, hypertrophic cardiomyopathy and following myocardial infarction. Patients with hypertension--in particular, those with left ventricular hypertrophy (LVH)--are also at greater risk of sudden cardiac death. We examined whether QT dispersion, which is easily obtained from a routine ECG, correlates with LVH.
