Consequently, increased toxicity of these drugs is observed ...Unreferenced date December 2009 Cardiac glycosides are medication drugs used in the treatment of congestive heart failure and cardiac arrhythmia . These glycoside s are found as secondary metabolite s in several plant s, but also in some animals, such as the milkweed butterfly milkweed butterflies . File Oleandrin.svg thumb Example of the chemical structure of oleandrin , one of the cardiac glycosides. Function Therapeutic uses of cardiac glycosides primarily involve the treatment of cardiac failure. Their utility results from an increased cardiac output by increasing the Inotrope force of contraction . By increasing intracellular calcium as described below, cardiac glycosides increase calcium induced calcium release and thus contraction. Drugs such as ouabain and digoxin are cardiac glycosides. Digoxin from the foxglove plant is used clinically, whereas ouabain is used only experimentally due to its extremely high potency. Normally, Na K ATPase sodium potassium pumps in the membrane of cells in this case, cardiac myocytes pump potassium ions in and sodium ions out. Cardiac glycosides inhibit this pump by stabilizing it in the E2 P transition state, so that sodium cannot be extruded intracellular sodium concentration therefore increases.

The phrase cardiac monitoring generally refers to continuous monitoring medicine monitoring with electrocardiography with assessment of the patients condition relative to their cardiac rhythm. It is different from hemodynamic monitoring, which monitors the pressure and flow of blood within the circulatory system. The two may be performed simultaneously on critical heart patients. A small monitor worn by an ambulatory patient is known as a Holter monitor . Transmitting data from a monitor to a distant monitoring station is known as telemetry or biotelemetry . Emergency Medical Services Ambulance services and other emergency medical services providers utilize heart monitors to assess the patient s cardiac rhythm. Providers licensed or certified at the Intermediate or Paramedic level are qualified to interpret EKGs. The finding of a cardiac dysrhythmia or for that matter, a normal sinus rhythm may give additional information about the patients condition or may be a sufficient diagnosis on its own to guide treatment. Treatment for specific cardiac rhythms is guided by Advanced Cardiac Life Support ACLS .

Cardiac nurses help treat conditions such as unstable Angina pectoris angina , cardiomyopathy , coronary artery disease , congestive heart failure , myocardial infarction and cardiac dysrhythmia under the direction of a cardiologist. Cardiac nurses perform postoperative care on a surgical unit, stress test evaluations, cardiac monitoring, vascular monitoring, and health assessments. Cardiac nurses must have Basic Life Support and Advanced Cardiac Life Support certification. In addition, cardiac nurses must possess specialized skills including electrocardiogram monitoring, defibrillation , and medication administration by continuous Intravenous therapy intravenous drip. Cardiac nurses work in many different environments, including coronary care unit s CCU , cardiac catheterization , intensive care unit s ICU , operating theatre s, cardiac rehabilitation centers, clinical research , cardiac surgery wards, cardiovascular intensive care unit s CVICU , and cardiac medical wards.

Cardiac sonographer also known as echocardiographer , or cardiac ultrasound technologist is a medical profession of sonographer s that specialize in the anatomy and function of the heart . It is a technical job that in the USA has traditionally required an Associates degree in Echo and passing a National Registry exam, but more and more often is requiring a Bachelors degree as the field gets more developed and complicated. Much like how a general sonographer would use sonography ultrasound to view a fetus inside a pregnant woman, cardiac sonographers use the same technology to examine and evaluate the heart chamber sizes, arrangement of the parts, muscle function, valve function and blood flow. Cardiac sonographers typically do not make diagnoses, but rather report their results to a cardiologist for further analysis. Educational requirements in U.S. Most schools that offer training for cardiac sonographers have several different programs available to students. Programs that are certificate based can be completed in about twelve 12 months allowing the candidate to make a relatively quick entrance into their chosen career. However, some students may choose to pursue a full four year degree in order to allow them to work at more advanced levels but most commonly, the course of study for those pursuing the cardiac sonographer profession is the two year associate s degree. Typically, an associate s degree satisfies the minimum educational requirement for most employers.
