Identify all components of a normal ECG rhythm- a typical, or normal ECG tracing of the heartbeat consists of a P. wave, a QRS complex, a T. wave and a U. wave (visible in 50-75% of cases).
Identify basic ECG rhythms -- ECG rhythms are printed on graph paper, the smaller squares represent .04 second; 1 second 25 small squares, etc. The basic rhythms are:
(Source: ECG Tutorial, 2006).
Identify basic dysrhythmias and relevant implications and nursing interventions -- There are a number of dysrhythmias that impact the nursing field: Sinus Bradycardia -- Heart rate less than 60 beats per minute, rhythm regular, duration normal, but slower respiration, may indicate beta blockers, brain injury, hypoglycemia, or substance use; Sinus Tachycardia -- excessive heart rate above 100 beats per minute, beats are normal but at a faster rate, may indicate fright, stress, or illness; Supraventricular Tacycardia (SVT) shows narrowing of BPM, thus increased activity is being caused by other organs, not the heart; Atrial Fibrillation, rhythm irregular, rate 100-160 BPM, P wave indistinguishable and firing randomly, PR level is not measurable; and numerous others. For the nurse interpreter, the warning signs are: distance between peaks (amplitude), odd QRS shapes,...
Heart Disease Relationship between cardiac arrest and coronary cardiac disease The heart is an essential organ in the human body, it keeps the individual alive. Understanding how the heart operates and functions is essential to help protect your heart from heart disease. Cardiac arrest and coronary heart disease are significant heart related illness that has a high mortality rate. It is important for individuals with pre-existing heart disease to understand the symptoms
Egyptian medicine. There are eight references used for this paper. Civilizations throughout the years have dealt with disease and illness in numerous ways. It is interesting to look at the Ancient Egyptians and determine how they practiced medicine during their time and how it relates to modern medicine. It is also important to examine the materials or tools involved in their medical practices, major medical discoveries, and methods used by
S. Congress that the prospects of stem cell research were so vast that it could touch all the realm of medicine (Connor 2000). An unlimited source of embryonic stem cells will solve the problem of shortage of transplants. Embryonic stem cells will save lives by curing generative diseases of the brain, hepatitis, diabetes, leukemia, rheumatoid arthritis, muscular dystrophy and cystic fibrosis and diseases of the heart and kidneys. But current
However, Harvard Medical School (HMS) reports that in that study of 1,400 patients, 222 "composite events occurred." Those "events" included 65 deaths, 101 "hospitalizations for congestive heart failure, 25 myocardial infarctions and 23 strokes." In an understatement, the HMS report - written by Dr. Singh - concluded that while improving the lives of patients with CKD is "of paramount importance," this particular study reveals, "...Aiming for a complete correction of
Scientists have been aware of the existence of these stem cells for many years but have only recently realized the potential medical applications of the cells. More than a decade ago, scientists discovered that if the normal connections between the early cellular progeny of the fertilized egg were disrupted, the cells would fall apart into a single cell progeny that could be maintained in a culture. These dissociated cells, otherwise
History of Magnetic Resonance Imaging (MRI) Getting an MRI scan may someday become as common as getting an X-ray. - Davis Meltzer, 1987 According to Gould (2004), on July 3, 1977, an event took place that would forever alter the landscape of modern medicine, although outside the scientific research community, this event hardly attracted any notice at all. The event in question was the first MRI exam ever performed on a human
