Ebstein's anomaly is a congenital heart defect in which the septal and posterior leaflets of the tricuspid valve are displaced downwards towards the apex of the right ventricle of the heart. [1] EA has great anatomical heterogeneity that generates a wide spectrum of clinical features at presentation and is complicated by the fact that the ...
Irregular heart rate, pulmonary regurgitation [3] Usual onset: From birth [4] Causes: Unknown [5] Risk factors: Alcohol, diabetes, >40, rubella during pregnancy [5] Diagnostic method: Based on symptoms, echocardiogram [6] Differential diagnosis: Transposition of the great arteries, Eisenmenger syndrome, Ebstein anomaly [7] Treatment: Open heart ...
Congenital heart anomaly, congenital heart disease: The normal structure of the heart (left) in comparison to two common locations for a ventricular septal defect (right), the most common form of congenital heart defect [1] Specialty: Cardiology: Symptoms: Rapid breathing, bluish skin, poor weight gain, feeling tired [2] Complications: Heart ...
The Lee–Carter model is a numerical algorithm used in mortality forecasting and life expectancy forecasting. [1] The input to the model is a matrix of age specific mortality rates ordered monotonically by time, usually with ages in columns and years in rows. The output is a forecasted matrix of mortality rates in the same format as the input.
Eisenmenger syndrome or Eisenmenger's syndrome is defined as the process in which a long-standing left-to-right cardiac shunt caused by a congenital heart defect (typically by a ventricular septal defect, atrial septal defect, or less commonly, patent ductus arteriosus) causes pulmonary hypertension [1] [2] and eventual reversal of the shunt into a cyanotic right-to-left shunt.
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
MDCalc was founded by two emergency physicians, Graham Walker, MD, and Joseph Habboushe, MD, MBA, [5] and provides over 500 medical calculators and other clinical decision-support tools. [6] The MDCalc.com website was launched in 2005. [5] In 2016, MDCalc launched an iOS app, [7] followed by an Android app in 2017. [8]
Among actuaries, force of mortality refers to what economists and other social scientists call the hazard rate and is construed as an instantaneous rate of mortality at a certain age measured on an annualized basis. In a life table, we consider the probability of a person dying between age (x) and age x + 1; this probability is called q x.
