The heart is one of the most important organs in the human body. The blood in the heart provides a person’s body with oxygen and nutrients. The electrical system of the heart is in control of when the heart pumps the blood. The heart’s electrical system is made of the sinoatrial node, the atrioventricular node, and the His-Purkinje system. When dealing with the electrical activity of the heart, voltage, current, and resistance are used. Receiving an electrical shock is very dangerous, and there are risks that come with it. Electric shocks can affect the chest, the nervous system, and the skin, which can all cause problems with the heart. Cardioversion and defibrillation are two procedures that can be done to the heart. These procedures have similarities and differences. Cardioversion should be used when a patient is suffering from a weak pulse, due to an electric shock. The sinoatrial node is …show more content…
Getting shocked is very dangerous because it can cause a person to die. “About 1,000 people in the United States die each year, as a result of electrocution” (Electric Shock). Electric shock can affect the heart because when a current is passed through the heart, ventricular fibrillation can occur. If it is not treated by defibrillation, the heart will eventually stop beating. “Electric shocks of voltage between 500 to 1,000 volts can give rise to internal burns” (Ladock). When the burns start affecting the internal organs, it can lead to heart failure. When the burn is so severe that it leads to organ failure, the healing process is very slow. To prevent electric shock from happening, it is important to stay away from electrical wires. Also, one should make sure the electricity is turned off. People should be cautious of capacitors. Capacitors are found in air conditioners or refrigerators. They store electricity, and can shock a person even when the circuit power is turned
However, the TASER has faced massive amounts of bad press and negative views among members of the public. Electro-muscular disruption has become a very controversial issue among society, with some describing it as extremely painful and a form of torture. The true power of the TASER has been witnessed over its short history, causing physical problems, psychological problems and even death. This is becoming more concerning with the TASER becoming the first resort rather than the last resort. With the TASER being carried by an ever-growing population of police officers, alternate forms of less lethal may need to be looked at.

...ending on the size and tolerances of the patients, the voltages could have ranged anywhere form 70 to 130 volts. As a direct effect from the large amounts of electricity being imposed into the patient’s body they will lose consciousness almost immediately. The shocks sent them in to convulsions or seizures and therefore increased their insulin levels. After a patient regains consciousness, he or she will not remember any of the events of being shocked.

The science and history of the heart can be traced back as far as the fourth century B.C. Greek philosopher, Aristotle, declared the heart to be the most vital organ in the body based on observations of chick embryos. In the second century A.D, similar ideas were later reestablished in a piece written by Galen called On the Usefulness of the Parts of the Body. Galen’s thesis was that the heart was the source of the body’s essential heat and most closely related to the soul. Galen made careful observations of the physical properties of the heart as well. He said “The heart is a hard flesh, not easily injured. In hardness, tension, in general strength, and resistance to injury, the fibers of the heart far surpasses all others, for no other instrument performs such continues, hard work as the heart”(Galen, Volume 1).
Power can be defined as the ability to influence or outright control the behavior of people. A variety of different things can drive power, including both knowledge and experience. Power in most cases is needed to establish authority. In today’s country, the United States government has a lot of power. It has so much power that even American citizens are beginning to complain about it. Having all this power and authority has allowed the government to make decisions quicker. However, by making decisions faster, some mistakes can be made and innocent people can be convicted. This point is directly exemplified when using two New Yorker articles, “Surviving Solitary” and ‘A Shot to The Heart.” Both articles consist of results produced quite
Atrial fibrillation (AF) is a cardiac arrhythmia. It is the most common arrhythmia and it has implications for patients and anaesthetists alike. The anaesthetist must take into consideration the physiological and pharmacological implications of this common arrhythmia.
Electricity is used in modern medicine to bring a recently dead person “back to life” in the form of defibrillators, so could enough electricity bring body parts sewed together to life? Defibrillators are used on people who have recently clinically died, and
Before ECT begins, patients are given a short-acting anaesthetic and a nerve-blocking agent, paralysing the muscles of the body to prevent them from contracting during the treatment and causing fractures. Oxygen is also given to patients to compensate for their inability to breathe. Then they receive either unilateral ECT or bilateral ECT. In unilateral ECT, an electrode is placed above the temple of the non-dominant side of the brain, and a second in the middle of the forehead. Alternatively in bilateral ECT, one electrode is placed above each temple. After this, a small amount of electrical current (approximately 0.6 amps) is passed through the brain, lasting about half a second. This produces a seizure that lasts up to one minute which affects the entire brain. ECT is usually give...
State: The cardiac cycle is composed of five stages which each trigger the relaxation or contraction of the atria or ventricles and direction of blood flow.
It is safe to say that tasers are not as lethal as guns, but they can still cause serious damage to individuals. This is because not everyone has the same body, and not everyone will have the same reaction to 50,000 volts of electricity. In the text, “Taser Controversy Refuses to Die” by author Matthew Davis, “the ‘less - than - lethal’ weapons have involved one 74 deaths in the United States and Canada” (5,1). Tasers are known as weapons that are not as dangerous as guns, but they somehow still cause a noticeable number of deaths in just the United States and Canada.
They have been many ways people had tried to avoid this cause yet it very difficult. They try to bury the wires and yet they still give out the EMFs. They try to warn people about the dangers of some electrical devices. Yet some people still get sick.
Cardiac dysrhythmias come in different degrees of severity. There are heart conditions that you are able to live with and manage on a daily basis and those that require immediate attention. Atrial Fibrillation is one of the more frequently seen types of dysrhythmias (NIH, 2011). The best way to diagnosis a heart condition is by reading a cardiac strip (Ignatavicius &Workman, 2013). Cardiac strips play an chief part in the nursing world allowing the nurse and other trained medical professionals to interpret what the heart is doing. In a normal strip, one can clearly identify a P wave before every QRS complex, which is then followed by a T wave; in Atrial Fibrillation, the Sinoatrial node fires irregularly causing there to be no clear P wave and an irregular QRS complex (Ignatavicius & Workman, 2013). Basically, it means that the atria, the upper chambers of the heart, are contracting too quickly and no clear P wave is identified because of this ‘fibrillation’ (Ignatavicius & Workman, 2013).

Electrocution occurs when a small, specific amount of electrical current flows through the heart for 1 to 3 seconds. 0.006-0.2 Amps (i.e. 6-200 milliamps) of current flowing through the heart disrupts the normal coordination of heart muscles. These muscles lose their vital rhythm and begin a process known as ventricular fibrillation. Death soon follows.
