Cardiac

Sudden cardiac arrest is a condition in which the heart suddenly and unexpectedly stops beating. When this occurs the blood flow stops to the brain and vital organs. Sudden cardiac arrest is not the same as a heart attack or myocardial infarction. A heart attack is when the blood flow to part of the heart is blocked.(ADD MORE) Without early intervention on average 360,000 people out of the hospital succumb to cardiac arrest. “ Cardiac arrest and sudden death account for 60 percent of all deaths

shape and size of cells Cardiac muscle is involuntary because the heart works all the time and never gets fatigued unlike skeletal muscle which is voluntary because it is used for body movement such as sitting, walking and lifting. Skeletal muscle differs from cardiac muscle as it is multinucleated compared with cardiac muscle that is uninucleated. This means skeletal muscle have more than one nucleus and cardiac muscle has one nucleus in the muscle cells. Also, cardiac muscle has semi-spindle shape-like

Getting Children Certified in CPR Cardiac arrest is one of the leading causes of death in adults each year, and 92% of cardiac arrest patients fail to survive. These people that fall victim to cardiac arrest fail to survive because parents, children, co workers, fellow students, and other people you associate with everyday lack the knowledge that it takes to give the victim the simple two step process of CPR. Learning CPR is easy to comprehend, and does not take a lot of time to learn the and master

Cardiac Conduction To complete this worksheet, select:         Module:  Distribution         Activity:  Animations         Title:  Cardiac Conduction 1. What is the function of the Conduction System? All cells must contract in a specific sequence. This sequence is determined by the pathway known as the conduction system. 2. Cardiac cells are connective and autorhythmic. What does this mean? Connective cells, action potentials, (excitatory signals) can propagate from

Cardiac Arrhythmias occurs when the electrical impulses of the heart don’t work properly, causing the heart to beat either too fast, too slow or irregular. There a two different types of cardiac arrhythmias; supraventricular and ventricular. The supraventricular arrhythmias occur when electrical abnormalities are generated in the sinoatrial node, atria, atrioventricular node, and the junctional tissue in the heart. The ventricular arrhythmias are generated in the ventricular conduction system and

The lack or delay in appropriate treatment for individuals who experience a sudden cardiac arrest has created a major public health disparity. Research into pre-hospital treatment and subsequent implementation has historically seen neglect by the medical and scientific community creating vast differences in survivability of cardiac arrests between demographic groups. In 2010, the American Heart Association and Emergency Cardiovascular Care program developed the 2020 impact goal to reduce death from

When not given CPR right away , the cardiac arrest victim may have no chance to survive until professional care providers arrive on the scene. On an average it takes three to four minutes for the EMS to get there. It is most effective immediately after a victim’s heart stops beating. According to The American Heart Association(2017), “For each minute CPR is not performed the chance of survival decreases by 10%”(para.5). Saying that by the time the EMS arrives to the scene that victim’s chance of

The human body consist of 680 skeletal muscles. The name of a muscle can distinguish its location, action, shape, and function. One such example is the biceps brachii, which is commonly referred to as biceps. As the name implies, this is a two-headed muscle. The term biceps brachii is a Latin phrase that means, "two-headed muscle of the arm." This is references to the fact that the muscle consists of two bundles of muscles. Each of these bundles has its own origin and share a common insertion point

Your heart beats approximately 100,000 times a day to circulate 7570 liters of blood. Cardiac muscle cells are called Cardiomyocytes. These cells are equipped with specialized organelles such as myofibrils, mitochondria, the sarcoplasmic reticulum for storage and release of calcium and the sarcolemma which is a membrane that encloses each muscle cell. Cardiomyocytes have a tremendous amount of mitochondria present inside the cell compared to many other cells, this gives the cardiomyocyte the ability

The process of resuscitating a patient after cardiac arrest depend on what type of dysthymia they are presenting with. The first action that the nurse should take is check for the patients’ consciousness. If the patient is unresponsive and the nurse cannot feel a pulse, usually the carotid pulse, the nurse should initiate a code without leaving the patients side. After initiating the code the nurse should start compressions. Compressions are a one-person job until additional help arrives. Once additional
