==Overview==
==Overview==
Cardiac arrest is synonymous with [[Clinical death]]. All disease processes leading to death have a period of (potentially) reversible cardiac arrest: the causes of arrest are, therefore, numerous. However, many of these conditions, rather than causing an arrest themselves, promote one of the "reversible causes" (see below), which then triggers the arrest (e.g. [[Choking]] leads to [[Hypoxia]] which in turn leads to an arrest). In some cases, the underlying mechanism cannot be overcome, leading to an unsuccessful resuscitation.
[[Sudden cardiac arrest]] ([[SCA]])  may be caused by underlying [[cardiac]] abnormality including [[coronary artery]] abnormality , [[hypertrophy]] of [[myocardium]], [[myocardial disease]], [[valvular heart disease]], [[congenital heart disease]], abnormality in [[conducting system]] and electrical instability. The type of [[cardiac disease]] that is associated with [[sudden cardiac death]] ([[SCD]]) depends on the [[age]] of the individual <ref name="pmid21131293">{{cite journal| author=Winkel BG, Holst AG, Theilade J, Kristensen IB, Thomsen JL, Ottesen GL | display-authors=etal| title=Nationwide study of sudden cardiac death in persons aged 1-35 years. | journal=Eur Heart J | year= 2011 | volume= 32 | issue= 8 | pages= 983-90 | pmid=21131293 | doi=10.1093/eurheartj/ehq428 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21131293  }} </ref> <ref name="pmid24604905">{{cite journal| author=Risgaard B, Winkel BG, Jabbari R, Behr ER, Ingemann-Hansen O, Thomsen JL | display-authors=etal| title=Burden of sudden cardiac death in persons aged 1 to 49 years: nationwide study in Denmark. | journal=Circ Arrhythm Electrophysiol | year= 2014 | volume= 7 | issue= 2 | pages= 205-11 | pmid=24604905 | doi=10.1161/CIRCEP.113.001421 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=24604905  }} </ref> <ref name="pmid27332903">{{cite journal| author=Bagnall RD, Weintraub RG, Ingles J, Duflou J, Yeates L, Lam L | display-authors=etal| title=A Prospective Study of Sudden Cardiac Death among Children and Young Adults. | journal=N Engl J Med | year= 2016 | volume= 374 | issue= 25 | pages= 2441-52 | pmid=27332903 | doi=10.1056/NEJMoa1510687 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=27332903  }} </ref> <ref name="pmid12472914">{{cite journal| author=Wisten A, Forsberg H, Krantz P, Messner T| title=Sudden cardiac death in 15-35-year olds in Sweden during 1992-99. | journal=J Intern Med | year= 2002 | volume= 252 | issue= 6 | pages= 529-36 | pmid=12472914 | doi=10.1046/j.1365-2796.2002.01038.x | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=12472914  }} </ref> <ref name="pmid15364331">{{cite journal| author=Chugh SS, Jui J, Gunson K, Stecker EC, John BT, Thompson B | display-authors=etal| title=Current burden of sudden cardiac death: multiple source surveillance versus retrospective death certificate-based review in a large U.S. community. | journal=J Am Coll Cardiol | year= 2004 | volume= 44 | issue= 6 | pages= 1268-75 | pmid=15364331 | doi=10.1016/j.jacc.2004.06.029 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=15364331  }} </ref> <ref name="pmid24344190">{{cite journal| author=Winkel BG, Risgaard B, Sadjadieh G, Bundgaard H, Haunsø S, Tfelt-Hansen J| title=Sudden cardiac death in children (1-18 years): symptoms and causes of death in a nationwide setting. | journal=Eur Heart J | year= 2014 | volume= 35 | issue= 13 | pages= 868-75 | pmid=24344190 | doi=10.1093/eurheartj/eht509 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=24344190  }} </ref> <ref name="pmid18424446">{{cite journal| author=Byrne R, Constant O, Smyth Y, Callagy G, Nash P, Daly K | display-authors=etal| title=Multiple source surveillance incidence and aetiology of out-of-hospital sudden cardiac death in a rural population in the West of Ireland. | journal=Eur Heart J | year= 2008 | volume= 29 | issue= 11 | pages= 1418-23 | pmid=18424446 | doi=10.1093/eurheartj/ehn155 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=18424446  }} </ref> <ref name="pmid21903060">{{cite journal| author=Eckart RE, Shry EA, Burke AP, McNear JA, Appel DA, Castillo-Rojas LM | display-authors=etal| title=Sudden death in young adults: an autopsy-based series of a population undergoing active surveillance. | journal=J Am Coll Cardiol | year= 2011 | volume= 58 | issue= 12 | pages= 1254-61 | pmid=21903060 | doi=10.1016/j.jacc.2011.01.049 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21903060  }} </ref>.

In a patient with sudden death, a thorough evaluation of potential causes is essential to exclude preventable causes of recurrence.
===Reversible Causes===
[[Cardiopulmonary resuscitation]] (CPR), including adjunctive measures such as defibrillation, intubation and drug administration, is the standard of care for initial treatment of cardiac arrest. However, most cardiac arrests occur for a reason, and unless that reason can be found and overcome, CPR is often ineffective, or if it does result in a return of spontaneous circulation, this is short lived. <ref name="RCUK2005">Resuscitation Council UK (2005). ''Resuscitation Guidelines 2005'' London: Resuscitation Council UK.</ref>. As highlighted above, a variety of disease processes can lead to a cardiac arrest, however they usually boil down to one or more of the "Hs and Ts" (see below).
 
====H's====
* [[Hypovolemia|'''H'''ypovolemia]] - A lack of circulating [[body fluids]], principally [[blood]] volume. This is usually (though not exclusively) caused by some form of [[bleeding]], [[anaphylaxis]], or [[pregnancy]] with gravid uterus. [[Cardiac arrest#Peri-arrest period|Peri-arrest treatment]] includes giving [[Intravenous therapy|IV fluids]] and [[blood transfusions]], and controlling the source of any [[bleeding]] - by direct pressure for external bleeding, or emergency surgical techniques such as [[esophagogastroduodenoscopy]] (i.e. [[esophageal varices]]) and [[thoracotomy]] for internal bleeding.
* [[Hypoxia|'''H'''ypoxia]] - A lack of [[oxygen]] to the [[heart]], [[brain]] and other [[vital organ]]s. This can be identified through a careful assessment of breath sounds and tuble placement. Treatment may include providing oxygen, proper ventilation, and good [[cardiopulmonary resuscitation|CPR]] technique.
* [[Hydrogen|'''H'''ydrogen]] ions ([[Acidosis]]) - An abnormal pH in the body as a result of shock, [[Diabetic ketoacidosis]], [[renal failure]], or [[tricyclic antidepressant]] overdose. This can be treated with proper ventilation, good [[cardiopulmonary resuscitation|CPR]] technique, and buffers like [[sodium bicarbonate]].
* [[Hyperkalemia|'''H'''yperkalemia]] or [[Hypokalemia|'''H'''ypokalemia]] - The most life threatening [[electrolyte]] derangement is [[hyperkalemia]] (too much potassium). The classic presentation is the [[chronic renal failure]] patient who has missed a [[dialysis]] appointment and presents with [[weakness]], [[nausea]], and broad [[QRS complex]]es on the [[electrocardiogram]]. The most important initial therapy is the administration of [[calcium]], either with [[calcium gluconate]] or [[calcium chloride]]. Other therapies may include nebulized [[albuterol]], [[sodium bicarbonate]], [[glucose]], and [[insulin]]. The diagnosis of [[hypokalemia]] (not enough [[potassium]]) can be suspected when there is a history of [[diarrhoea]] or [[malnutrition]]. Loop [[diuretic]]s may also contribute. The [[electrocardiogram]] may show depressed T waves and prominent U waves. [[Hypokalemia]] is an important cause of acquired [[long QT syndrome]], and may predispose the patient to [[torsades de pointes]]. [[Digitalis]] use may increase the risk that [[hypokalemia]] will produce life threatening [[arrhythmia]]s.
* [[Hypothermia|'''H'''ypothermia]] - A low [[body temperature|core body temperature]], defined clinically as a [[temperature]] of less than 35 degrees Celsius. The patient is re-warmed either by using a [[heart-lung machine|cardiac bypass]] or by irrigation of the body cavities (such as thorax, peritoneum, bladder) with warm fluids; or warmed [[IV]] fluids. [[CPR]] only is given until the core body temperature reached 30 degrees Celsius, as [[defibrillation]] is ineffective at lower temperatures. Patients have been known to be successfully resuscitated after periods of hours in hypothermia and cardiac arrest, and this has given rise to the often-quoted medical truism, "You're not dead until you're warm and dead."
* [[Hypoglycemia|'''H'''ypoglycemia]] or [[Hyperglycemia|'''H'''yperglycemia]] - Low blood glucose from insulin reactions, [[diabetic ketoacidosis|DKA]], [[nonketotic hyperosmolar coma]]. This condition can be suspected when the patient is known to be a [[diabetic]]. The treatment may include fluids, [[potassium]], [[glucose]] (for hypoglycemia), and [[insulin]] (for hyperglycemia).
 
====T's====
* [[Tablets|'''T'''ablets]] or [[Toxins|'''T'''oxins]] - [[Tricyclic antidepressant]]s, [[phenothiazines]], [[beta blocker]]s, [[calcium channel blocker]]s, [[cocaine]], [[digoxin]], [[aspirin]], [[acetominophen]]. This may be evidenced by items found on or around the patient, the patient's medical history (i.e. drug abuse, medication) taken from family and friends, checking the [[medical records]] to make sure no interacting drugs were prescribed, or sending [[blood]] and [[urine]] samples to the [[toxicology]] lab for report. Treatment may include specific [[antidote]]s, fluids for volume expansion, vasopressors, [[sodium bicarbonate]] (for [[tricyclic antidepressant]]s), [[glucagon]] or [[calcium]] (for [[calcium channel blocker]]s), [[benzodiazepine]]s (for [[cocaine]]), or [[cardiopulmonary bypass]].
* [[Cardiac tamponade|Cardiac '''T'''amponade]] - Blood or other fluids building up in the [[pericardium]] can put pressure on the heart so that it is not able to beat. This condition can be recognized by the presence of a narrowing [[pulse pressure]], muffled [[heart sounds]], distended neck veins, [[electrical alternans]] on the [[electrocardiogram]], or [[echocardiogram]]. This is treated in an emergency by inserting a needle into the [[pericardium]] to drain the fluid ([[pericardiocentesis]]), or if the fluid is too thick then an emergency [[thoracotomy]] is performed to cut the pericardium and release the fluid.
* [[Tension pneumothorax|'''T'''ension pneumothorax]] - The build up of air into one of the [[pleural cavity|pleural cavities]], which causes a [[mediastinum|mediastinal]] shift. When this happens, the [[great vessels]] (particularly the [[superior vena cava]]) become kinked, which limits [[blood]] return to the [[heart]]. The condition can be recognized by severe air hunger, [[hypoxia]], jugular venous distension, hyperressonance to percussion on the effected side, and a tracheal shift away from the effected side. The tracheal shift often requires a chest [[x-ray]] to appreciate. This is relieved in an emergency by a needle [[thoracotomy]] (inserting a needle catheter) into the 2nd [[intercostal space]] at the mid-[[clavicle|clavicular]] line, which relieves the pressure in the [[pleural cavity]].
* [[Thrombosis|'''T'''hrombosis]] ([[Myocardial infarction]]) - If the patient can be successfully resuscitated, there is a chance that the [[myocardial infarction]] can be treated, either with [[thrombolysis|thrombolytic therapy]] or [[percutaneous coronary intervention]].
* [[Thrombosis|'''T'''hromboembolism]] ([[Pulmonary embolism]]) - Usually diagnosed at autopsy. Patients in [[asystole]] or [[pulseless electrical activity]] have a poor prognosis. If this can be detected early, the patient may receive [[dopamine]], [[heparin]], and [[thrombolytic]]s.
* [[Physical trauma|'''T'''rauma]] ([[Hypovolemia]]) - Reduced blood volume from acute injury or primary damage to the [[heart]] or [[great vessels]]. Cardiac arrest secondary to [[Physical trauma|trauma]], particularly [[blunt trauma]], has a very poor [[prognosis]].

Overview

Sudden cardiac arrest (SCA) may be caused by underlying cardiac abnormality including coronary artery abnormality , hypertrophy of myocardium, myocardial disease, valvular heart disease, congenital heart disease, abnormality in conducting system and electrical instability. The type of cardiac disease that is associated with sudden cardiac death (SCD) depends on the age of the individual [1] [2] [3] [4] [5] [6] [7] [8].
