• Cardiac output — (Q or or CO ) is the volume of blood being pumped by the heart, in particular by a left or right ventricle in the time interval of one minute. CO may be measured in many ways, for example dm3/min (1 dm3 equals 1000 cm3 or 1 litre). Q is… …   Wikipedia

• Cardiac input — (CI) is the inverse operation of cardiac output (CO). Cardiac output implies ejection fraction. Ejection fraction is an easily understood and imaged mathematical model of systole. Ejection Fraction (EF) = End Systolic Volume (ESV) divided by End… …   Wikipedia

• Cardiac glycoside — Cardiac glycosides are drugs used in the treatment of congestive heart failure and cardiac arrhythmia. These glycosides are found as secondary metabolites in several plants, but also in some animals. Some of these compounds (ouabain and some frog …   Wikipedia

• Cardiac ventriculography — is a medical imaging test used to determine a patient s cardiac function in the right, or more typically, left ventricle. Cardiac ventriculography involves injecting contrast media into the heart s ventricle(s) to measure the volume of blood… …   Wikipedia

• Cardiac index — (CI) is a vasodynamic parameter that relates the cardiac output (CO) to body surface area (BSA), thus relating heart performance to the size of the individual. The unit of measurement is litres per minute per square metre (l/min/m2). The index is …   Wikipedia

• Cardiac function curve — A cardiac function curve is a graph showing the relationship between right atrial pressure (x axis) and cardiac output (y axis). Shape of curve It shows a steep relationship at relatively low filling pressures and a plateau, where further stretch …   Wikipedia



• Cardiac Output — Das Herzminutenvolumen (HMV) oder Herzzeitvolumen (HZV) ist das Volumen des Blutes, welches in einer Minute vom Herz durch den Blutkreislauf gepumpt wird. Das Herzminutenvolumen ist also ein Maß für die Pumpfunktion des Herzens. Das… …   Deutsch Wikipedia

• cardiac output — blood volume in liters pumped by the left ventricle of the heart per minute. * * * ▪ physiology       in human physiology, volume of blood expelled by either ventricle of the heart. It is customarily expressed as minute volume, or litres of blood …   Universalium

• Cardiac output — The amount of blood that is pumped by the heart per minute. The amount of blood that is put out by the left ventricle of the heart in one contraction is called the stroke volume. The stroke volume multiplied by the heart rate is the cardiac… …   Medical dictionary

• Cardiac arrest — A medical emergency with absent or inadequate contraction of the left ventricle of the heart that immediately causes bodywide circulatory failure. The signs and symptoms include loss of consciousness; rapid shallow breathing progressing to apnea… …   Medical dictionary
