Common Characteristics of Cardiac Arrhythmias Under normal, healthy conditions the human heart beats 60 to 100 times a minute. In the course of a day, the heart pumps an equivalent of 2,000 gallons of blood, carrying essential oxygen and other nutrients to all of the body's cells. Ultimately, the brain coordinates this complex process, but the heart also has its own semi-independent power station. Most of this electrical activity is carried out by pacemaker cells located in the upper right-hand

demands of our aging population (Narang et al., 2016). Nurses caring for patients in the cardiac catheterization laboratory are key members of the cardiovascular workforce. While there is research to support the development of nurses working in the pre- and post-cardiac catheterization laboratory settings; current literature reveals little information about the development of nurses working in the cardiac catheterization laboratory (Currey, White, Rolley, Oldland, & Driscoll, 2015).

involvement in postoperative care, cardiac rehabilitation has many direct health benefits that solidify the need for implementation. Monpere (1998) noted that CR has been able to improve exercise tolerance and reduce long term mortality due to post-myocardial infarction and is rather cost effective. Additionally, CR can improve quality of life though its multi-faceted approach. Lausten et al. (2017) reported that it is significantly associated with prevention of cardiac morbidity and mortality and can

To keep the blood moving around the body supplying vital nutrients to cells and removing waste, a cycle of contractions (systole) and relaxations (diastole) take place, this cycle is known as the cardiac cycle. There are three stages to the cardiac cycle, all stages happen during one heartbeat (cycle) and take less than a second in total (Revisionworld.com, 2017), these different stages are pictured in figure 11. During stage one the pressure in both ventricles decreases as they relax, the atrioventricular

structure. It has many different functions and is vital to human life. The heart also supplies the body with oxygen and other nutrients and other numerous things. There are many different parts in the heart contributing to the endless cycle. “The cardiac cycle is a sequence of events that take place in the heart in each beat” (AlMasri, 2010). There are 4 chambers in the heart, the upper chambers are the left and right atriums. The lower chambers are the left and right ventricles, they are very important

important? The heart is analogous to any other muscle inside the human figure in seeing that the aforementioned contracts and expands. Furthermore, each time the heart contracts it does so with all its dynamism. The pumping of the heart is titled the Cardiac Cycle. The heart pumps blood, retains our blood pressure, and eradicates the waste products. For example, the brain requires oxygen with glucose, which, if not received continuously, will cause it to lose cognizance. Essentially, if the heart was

Approximately three hundred thousand cardiac arrests occur annually in the United States, making it one of the leading causes of death nationally (1). Pulseless electrical activity (PEA) is one of the most common forms of cardiac arrest and is generally associated with poor patient outcomes. It has been widely theorized that a focused cardiac ultrasound exam (FoCUS) can play both a diagnostic and a prognostic role during PEA cardiac arrest; however, it has not been adequately studied to-date. This

who are learning cardiac nursing would benefit from technology driven learning devices. Students who are studying cardiac nursing would greatly benefit and improve their performance while studying in a learning lab. Today there is many devices, and computer programs that could assist in teaching the fundamentals of cardiac nursing. Many technology based equipment is available, the mannequin for instance could be used in many different scenarios to teach cardiac nursing.

too slow or too fast; it may stay steady or become chaotic (irregular and disorganized). Some arrhythmias are very dangerous and cause sudden cardiac death, while others may be bothersome but not life threatening. This paper will discuss, the cardiac conduction system, arrhythmia types, symptoms, diagnosis, and treatments. The electrical stimulus in cardiac muscles (action potentials) does not come from the nervous

The cardiac muscle cell embraces most of the hearts mass. It plays the most important significant role in the heart, pumping blood through the heart and into the body. It’s a long-life source, which never stops pumping. It’s continuous and persists an entire lifetime without unfluctuating or skipping a beat. The cardiac muscle is strong and has a long durability, which sustains its unique heartbeat. The Cardiac hearts muscle has the capability to spread rapid electrochemical signals throughout the
