Background:Epidemiological data suggest increased risk of sudden death during and immediately after hemodialysis. Microvolt T-wave alternans (mTWA) is an electrocardiogram (ECG) measure of abnormal ...

Pre-eclampsia complicates approximately 6–8% of all pregnancies. Epidemiologic studies have demonstrated a relationship between pre-eclampsia and cardiac morbidity and mortality later in life, but the ...

Primary repolarization abnormalities such as ST or T wave changes are associated with higher risk of CHD mortality; however, the prevalence of primary repolarization abnormalities is low and their ...

Early repolarization is a common finding in young, healthy individuals. It appears as mild ST segment elevation that can be diffuse; however, it is more prominent in the precordial leads. The ST ...

Ventricular repolarization (VR) is a crucial step in cardiac electrical activity because it corresponds to a recovery period setting the stage for the next heart contraction. Small perturbations of ...

Left ventricular hypertrophy can be diagnosed on ECG with good specificity. When the myocardium is hypertrophied, there is a larger mass of myocardium for electrical activation to pass through; thus ...

Classic changes of ischemia may be described or explained as follows: 1. ST-segment elevations or depressions that are usually localized (but may be diffuse) and may be associated with such T-wave ...

Repolarization dispersion has been linked to echocardiographic measures of diastolic dysfunction in past research, and a recent study found it potentially indicative of pulmonary arterial hypertension ...

Epidemiologic evidence indicates that air pollution adversely affects the cardiovascular system, leading to increased cardiovascular morbidity and mortality. However, the mechanisms of such an ...
