  • cardiac asthma

    Left heart failure and pulmonary edema with wheezing respirations.

  • cardiac cycle

    The period from one cardiac contraction to the next. Each cardiac cycle includes ventricular contraction (systole) and relaxation (diastole).

  • cardiac output

    The amount of blood pumped by the heart per minute, calculated by multiplying the stroke volume times the heart rate per minute.

  • cardiac rupture

    A life-threatening complication of acute myocardial infarction that can involve the papillary muscle, interventricular septum, or myocardium.

  • cardiac standstill

    Asystole; absence of cardiac contractions.

  • cardiac tamponade

    Inadequate cardiac contraction, failing cardiac output, and shock, caused by the accumulation of fluid or blood in the pericardium.

  • cardiac work

    The energy consumed by the heart in maintaining cardiac output. Cardiac work is increased by increases in heart rate or peripheral vascular resistance.

  • cardiogenic

    Of cardiac origin.

  • cardiogenic shock

    A serious complication of acute myocardial infarction in which ventricular damage is so extensive that the heart is unable to maintain adequate output to vital organs.

  • cardiopulmonary arrest

    Cessation of cardiac and respiratory activity.

  • cardiopulmonary resuscitation (CPR)

    Artificial ventilation and external chest compression.

  • cardiotonic drugs

    Drugs that increase the rate and force of myocardial contractions.
