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 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 Circulatory 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: Read more or ask a question about Circulatory arrest1) 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 :).

Designed for both out-of-hospital and in-hospital use, LUCAS is indicated for treatment of adult patients who have acute circulatory arrest defined as absence of spontaneous breathing and pulse, as well as loss of consciousness. The goal of the BioTime research project is to use HetaCool to increase the time during which a patient may be maintained in hypothermic cardiac and circulatory arrest during surgery. Letsou, of the University of Texas Medical Center's Department of Cardiothoracic and Vascular Surgery, presented a series of canine experiments involving the revival and long term survival of dogs after two hours of hypothermic circulatory arrest. |
