cardiac arrest

arrest /ar·rest/ (ah-rest´) cessation or stoppage, as of a function or a disease process.

---

cardiac arrest  sudden cessation of the pumping function of the heart with disappearance of arterial blood pressure, connoting either ventricular fibrillation or ventricular standstill.

developmental arrest  a temporary or permanent cessation of development.

epiphyseal arrest  premature interruption of longitudinal growth of bone by fusion of the epiphysis and diaphysis.

maturation arrest  interruption of the process of development, as of blood cells, before the final stage is reached.

sinus arrest  a pause in the normal cardiac rhythm due to a momentary failure of the sinus node to initiate an impulse, lasting for an interval that is not an exact multiple of the normal cardiac cycle.

cardiac arrest

n.

Abbr. CA A sudden cessation of cardiac function, resulting in loss of effective circulation.

---

Cardiac arrest

A condition in which the heart stops functioning. Fibrillation can lead to cardiac arrest if not corrected quickly.

cardiac arrest

Etymology: Gk, kardia + L, ad + restare, to withstand

a sudden cessation of cardiac output and effective circulation. It is usually precipitated by ventricular fibrillation or ventricular asystole. When cardiac arrest occurs, delivery of oxygen and removal of carbon dioxide stop, tissue cell metabolism becomes anaerobic, and metabolic and respiratory acidosis ensue. Immediate initiation of cardiopulmonary resuscitation is required to prevent heart, lung, kidney, and brain damage and death. Also called cardiopulmonary arrest. See also cardiac standstill, cardiopulmonary resuscitation.

cardiac arrest,

n condition characterized by the sudden, complete cessation of all cardiac functioning.

---

cardiac,

adj relating to the heart.

cardiac arrest,

n a stopping of heart action; a complete cessation of heart function.

---

arrest

sudden cessation or stoppage.

---

cardiac arrest

sudden and often unexpected stoppage of effective heart action. Either the periodic impulses which trigger the coordinated heart muscle contractions cease or ventricular fibrillation or flutter occurs in which the individual muscle fibers have a rapid irregular twitching.

epiphyseal arrest

premature arrest of the longitudinal growth of bone due to fusion of the epiphysis and diaphysis.

maturation arrest

interruption of the process of development, as of blood cells, before the final stage is reached.

sinoatrial arrest

a disturbance in cardiac conduction in which the sinoatrial node intermittently fails to generate an impulse. There are no P waves or PQRS-T complexes for at least twice the normal R-R interval. If the pauses are long enough, junctional or ventricular escape complexes may occur. Occurs most commonly in brachycephalic dogs, causing only minor clinical signs.

cardiac arrest

Asystole Cardiac pacing Complete cessation of the heart's normal and rhythmic electrical and/or mechanical activity

Patient discussion about cardiac arrest.

Q. WHAT IS CARDIAC ARREST why do people have IT?

A. cardiac arrest is when the heart stops pumping blood. stops working. it can happen in a few cases:
1) it doesn't get oxygen and there for a part of it dies and make the whole heart stopping- heart attack.
2) in electric shock it may cause the electric pulse that generate movement in the heart to stop.
3)from harsh septic shock.
4) from any shock actually :).
