Cardiac arrest is a sudden deficiency of heart function due to which it suddenly ceases to beat and thus stops the action of pumping blood. For this reason the body tissues and those of the brain, in particular, will no longer be perfused by blood and oxygen resulting in loss of consciousness and, without an appropriate and rapid intervention, death within minutes.
Causes:
The most common cause of cardiac arrest is represented by an arrhythmia called ventricular fibrillation, in which the rapid and unpredictable electrical impulses cause a flicker that prevents the ventricles the heart from pumping blood. In a person with a healthy heart, an irregular heart rhythm long-term cannot develop without an external trigger, such as an electric shock, the

The ICD is a continuous function of monitoring heart rhythm. If the heart rate falls below the physiological frequency behaves as a normal pacemaker and stimulates contractions. If the heartbeat increases alarmingly heart defibrillators.
Plant coronary artery bypass: If the coronary arteries are blocked to improve the flow of blood that supplies the heart can be implanted by pass of jumping the obstruction using vascular tissue collected from the patient.
Ablation of cardiac tissue using radio frequency catheter: This is to stop abnormal paths of the electrical signal generated in the heart 's natural pacemaker. They are used for these purpose radiofrequency electrodes that are mounted on special catheters that are inserted into the heart through an artery.

Angina, Myocardial Infarction, and Cardiac Arrest Comparison and Contrast Hannah Bunce Fayetteville Technical Community College Angina, Myocardial Infarction, and Cardiac Arrest Comparison and Contrast Three of the most commonly occurring cardiac related events: angina, myocardial infarction, and cardiac arrest, are commonly confused. However, there is a huge difference between each of them. It is crucial to be informed of each of these cardiovascular emergencies and to be able to differentiate between them. As a medical professional it is also very important to know the appropriate care for each these cardiac related emergencies.
1.Congestive Heart Failure also known as (heart failure) is a life threatening condition. Heart Failure is caused when someone has a weak heart. It usually happens when the bodies blood pump to the heart is not pumping blood to the heart correctly.
Cardiac causes. 4.4. Cerebrovascular causes. 4.5. Other causes.
Damaged heart valves, toxic exposure, such as alcohol, prolonged arrhythmias, and infections are all other causes
Systolic and Diastolic Heart Failure Heart failure occurs when the heart cannot pump enough blood for the body due to a weakened or damaged heart. The heart 's pumping action moves oxygen-rich blood as it travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The left ventricle supplies most of the heart 's pumping power, so it 's larger than the other chambers and essential for normal function. (American Heart Association). In left-sided or left ventricular heart failure, the left side of the heart must work harder to pump the same amount of blood.
Administer a shock if it says shock. If the AED does not advise a shock, then you should keep doing CPR. How To Use An Automated External Defibrillator An AED is a device that can save the life of a person who experiences sudden cardiac arrest. Before you use an AED, you should check to make sure that no water is nearby.
Atrial fibrillation (AF) is an important risk factor for ischemic stroke. AF increases the risk of stroke five fold and contributes to at least 15% of all strokes. Therefore, stroke prevention with the use of antithrombotic therapy is central to the overall management strategy of patients with AF. The first factor to consider is stroke risk assessment. The CHADS2 or CHA2DS2-VASc risk stratification method is used to direct the treatment of patients with AF by assessing a patient’s risk for stroke.
aegan Hope 02/10/2018 PHIL-2306-I02 Dr. Griffin Nelson Organ Donation and Relativism Five years ago, Selena Gomez was diagnosed with lupus. “According to the Mayo Clinic, lupus is a chronic inflammatory disease that occurs when your body’s immune system attacks your own tissues and organs” (abc news). Gomez was told by doctors she had lupus nephritis and that she would be needing a kidney transplant. Luckily her friend, the star of ‘Secret Life of the American Teenager”, Francia Raisa, donated a kidney to her. “Not everyone is lucky enough to have a donor.”
Also, that it is a failure to the cardiovascular system in which the blood circulation decrease and eventually ceases. The second thing I learned, is that shock can be both cardiovascular and non-cardiovascular. Three major cardiovascular causes of shock are: poor pump function blood or fluid loss from blood vessels and poor vessel function.
you can take to help someone in your life. Cardiopulmonary resuscitation (CPR) is a lifesaving technique useful in many emergency, including
Causes and symptoms Shock is caused by three major categories of problems: cardiogenic (meaning problems associated with the heart 's functioning); hypovolemic (meaning that the total volume of blood available to circulate is low); and septic shock (caused by overwhelming infection, usually by bacteria). Cardiogenic shock can be caused by any disease, or event, which prevents the heart muscle from pumping strongly and consistently enough to circulate the blood normally. Heart attack, conditions which cause inflammation of the heart muscle (myocarditis), disturbances of the electrical rhythm of the heart, any kind of mass or fluid accumulation and/or blood clot which interferes with flow out of the heart can all significantly affect the heart 's ability to adequately pump a normal quantity of blood.
Introduction The narrative is strikingly familiar. Police are called by concerned friends or family to deal with an out of control male. The callers report that the suspect has been acting in a bizarre fashion for a number of hours and has been destroying furniture in the house. They are worried that he will hurt himself and are insistent that he be brought to the hospital for observation.
Brain death is when the person no longer has reflexes or any response to vigorous external stimuli. Brain death is the complete and irreversible loss of brain function necessary to sustain life. Immediately after the heart stops beating, the body rapidly cools down until it reaches room temperature (“Algor Mortis”). Without the heart pumping, blood coagulates in the veins, arteries and capillaries, causing the entire body to stiffen.
Myocardial Infarction which is another word for Heart-attack. When you have an heart-attack your blood is not getting to your heart's muscle. This means your arteries are clogged. Blood is pumped through your arteries to all of the parts in your body. If you have a heart condition you shouldn't smoke, you should diet and exercise, you should watch your Blood Pressure if you have to take medication for your Blood Pressure make sure you take the prescribed medication.
The human nervous system communicates with electrical impulses. Tasers use similar electrical impulses called Taser-Waves which override the nervous system causing the uncontrollable contractions to the muscles and causing the person to remain immobile. The American Heart Association published an article in its journal Circulation that looked at eight cases of Taser use on suspects and found that Taser usage can result in cardiac arrest in a person. Dr. Douglas Zipes, Of Indiana University Krannert Institute of Cardiology, said, “can cause cardiac electrical capture and provoke cardiac arrest, as a result of an abnormally rapid heart rate and uncontrolled fluttering contractions. ”(According to American Heart
