|
afterload |
the amount of resistance to ejection of blood from a ventricle
|
|
|
anuria
|
urine output of less than 50 mL per 24 hours
|
|
|
ascites
|
an accumulation of serous fluid in the peritoneal cavity
|
|
|
CO - cardiac output
|
the amount of blood pumped out of the heart in 1 minute
|
|
|
CRT - cardiac resynchronization therapy
|
a treatment for heart failure in which a device paces both ventricles to synchronize contractions
|
|
|
compliance
|
the elasticity or amount of "give" when blood enters the ventricle
|
|
|
CHF - congestive heart failure
|
a fluid overload condition (congestion) associated with heart failure
|
|
|
contractility
|
the force of ventricular contraction; related to the number and state of myocardial cells
|
|
|
diastolic heart failure
|
the inability of the heart to pump sufficiently because of an alteration in the ability of the heart to fill; current term used to describe a type of heart failure
|
|
|
DOE - dyspnea on exertion
|
shortness of breath that occurs with exertion
|
|
|
EF - ejection fraction
|
percentage of blood volume in the ventricles at the end of diastole that is ejected during systole; a measurement of contractility
|
|
|
HF - heart failure
|
the inability of the heart to pump sufficient blood to meet the needs of the tissues for oxygen and nutrients; s/s of pulmonary and systemic congestion may or may not be present
|
|
|
ICD - implantable cardioverter defibrillator
|
a device implanted in patients with ventricular dysrhythmias that detects and treats dysrhythmias
|
|
|
left-sided HF (left ventricular failure)
|
inability of the left ventricle to fill or pump (empty) sufficient blood to meet the needs of the tissues for oxygen and nutrients; traditional term used to describe patient's symptoms of heart failure
|
|
|
oliguria
|
diminished urine output of less than 400 mL per 24 hours
|
|
|
orthopnea
|
shortness of breath when lying flat
|
|
|
PND - paroxysmal nocturnal dyspnea
|
shortness of breath that occurs suddenly during sleep
|
|
|
pericardiocentesis
|
procedure that involves aspiration of fluid from the pericardial sac
|
|
|
pericardiotomy
|
surgically treated opening of the pericardium
|
|
|
preload
|
the amount of myocardial stretch just before systole caused by the volume of blood presented to the ventricle
|
|
|
pulmonary edema
|
abnormal accumulation of fluid in the interstitial spaces or in the alveoli of the lungs
|
|
|
PEA - pulseless electrical activity
|
condition in which electrical activity is present but there is not an adequate pulse or blood pressure because of ineffective cardiac contraction or circulating blood volume
|
|
|
pulses paradoxus
|
systolic blood pressure of more than 10 mm Hg higher during exhalation than during inspiration; difference is normally less than 10 mm Hg
|
|
|
right-sided HF (right ventricular failure)
|
inability of the right ventricle to fill or pump (empty) sufficient blood to the pulmonary circulation
|
|
|
SV - stroke volume
|
amount of blood pumped out of the ventricle with each contraction
|
|
|
systolic heart failure
|
inability of the heart to pump sufficiently because of an alteration in the ability of the heart to contract; current term used to describe a type of HF
|
