Cardiology

In May of 2015, I was diagnosed with Postural Orthostatic Tachycardia Syndrome. My life became a whirlwind of hospital visits, testing, and a constantly changing list of prescriptions. It took months of doctor visits and a wide range of diagnoses to finally be correctly diagnosed with P.O.T.S. The condition falls under the umbrella of dysautonomia and is characterized by a rise in heart rate exceeding thirty beats per minute when transferring from a sitting to standing position. The body’s…

Cardiomyopathy is an unhealthy heart muscle that can't work or contract satisfactorily. Cardiomyopathy leads to the failure of the heart muscle to address the requirements of the body for oxygen-rich blood and evacuation of carbon dioxide and other wastes. There are numerous reasons for cardiomyopathy, yet the final outcome is a heart that is frail and can't keep up a normal discharge part or cardiovascular activity. Symptoms: There may be no symptoms or signs at the beginning of cardiomyopathy.…

Patient Care Technology Identification and Definition A leadless pacemaker is a small, self-contained unit that is placed on the inside wall of the heart through a thin, flexible catheter. In other words, it is a pacemaker without the leads (Bongiorni et al., 2016). A pacemaker is a small device that is placed in the chest or abdomen to help control abnormal heart rhythms. This device uses low-energy electrical pulses to prompt the heart to beat at a normal rate (60-100 beats per minute) (Mann…

WIllem Einthoven is the creator of the electrocardiogram, it is used today everywhere in the health field, in ambulances, hospitals, etc. This is to show how it was first made, and who created it, and first developed it. Along with how it has helped people today in modern times. Understanding how willem einthoven had a compelling achievement in understanding the heart rhythms and how to analyze them. In this essay I will help you understand what is essential to vital human life today, and how it…

Heart failure is a common killer of both men and women in the United States every year. It is a very serious issue that plagues this country and other developed countries like it. Heart failure is a syndrome with many risk factors, such as, age, obesity, congenital heart diseases, and many others. A client is considered to be in heart failure, when their heart is unable to profuse tissues in the body with oxygenated and nutrient rich blood for tissue to sufficiently function. A client when…

Abstract Whens humans exercise, their oxygen supply needs to be increased in order to produce the energy needed to sustain this workload. Humans will use a variety of cardio-respiratory mechanisms in order to supply and meet the oxygen levels the body needs during exercise. In this study we wanted to see how different individuals respond to exercise, specifically how long they can work and how efficiently they work. We predicted that females who exercise will have a higher relative-VO2, higher…

Hypertension is an asymptomatic vascular disorder that displays an increased systolic (>120mm/Hg) or diastolic (>80mm/Hg) pressure. The etiology of the disorder is unknown, and is therefore known as an idiopathic disorder but a variety of factors do play a role in the pathogenesis of the disorder such as coarctation of the aorta, salt sensitivity, renal abnormalities, hormonal disorders and neurological malfunctions. Therefore, the manifestation of the disorder is a complex interaction…

AN ATHLETE 'S HEART Everyone knows normal daily exercise is beneficial to the heart. It helps reduce the risk of heart disease, reduces weight, lowers blood pressure, and improves cholesterol. A difference in the appearance of the heart can be seen between normal exercise and those of highly trained athletes. Athletic hearts undergo cardiac remodeling of chambers and physiological changes because the heart is working harder to pump blood to the rest of the body during extreme physical activity…

Heart Failure Even though heart failure is a chronic condition, acute or decompensated heart failures require ICU admission. Otherwise, patients already admitted to the ICU for other diagnoses may be affected by heart failure as a complication. Postmyocardial injury/postinfarction patients and postoperative patients are included in this category. To detect early heart failure or heart failure in compensated stages, ventricular filling pressures are evaluated against stroke volume. The ICU nurse…

The Cardiac Cycle The cardiac cycle is the sequence of events that occur in the heart during one heart beat. It is how the heart operates, and what exactly happens when it contracts and relaxes. The heart is equipped with four chambers and one-way valves that work with precision to pump blood to and from the body. The heart regulates blood volume to support efficient circulation to the cells, tissues, organs, and systems. It provides oxygen and nutrients to the bodies tissue while also…
