Tetralogy of Fallot Tetralogy of Fallot‚ abbreviated TOF‚ is a congenital heart defect that occurs within the hearts of infants and young children. The disease is named after the doctor who described the four heart defects common to several of his patients in 1888. It is present at birth and is usually diagnosed during infancy. There are times‚ though‚ that it may not be detected until later in life‚ depending on the severity of the defects and symptoms. The problems that occur within the

Approximately one third of all Wolff- Parkinson- White syndrome patients will develop auricular fibrillation. Auricular fibrillation is a cardiac arrhythmia that is seen in patients with pathway problems in the heart. Wolff- Parkinson- White syndrome can be diagnosed with a simple test called an echocardiogram or also known as an EKG. This test would show an irregular

Extra Credit Assignment A: Terms 1 – 20 1.) Peripheral artery disease (PAD) is similar to coronary artery disease (CAD). PAD is a problem in the circulatory system where your arteries become narrow which leads to less blood flow to your limbs. PAD develops in your extremities‚ more commonly your legs‚ which can make walking become painful‚ also known as claudication. 2.) Aortic valve stenosis (AVS) is when the aortic valve‚ which is between the aorta and left ventricle of the heart‚ becomes narrow

Long-Term Anticoagulation Therapy) was conducted. It served to compare two fixed doses of Dabigatran Etexilate‚ both of which were administered blindly‚ and compare with an open label use of warfarin in patients that were suffering from atrial fibrillation (Connolly et al. 2009). The methodology of this study was as follows: trial participants were randomly assigned to either one of two doses of Dabigatran Etexilate‚ or warfarin. The two doses of Dabigatran Etexilate were either 110 mg or 150 mg

Acute renal failure is the sudden loss of the kidneys ability to function; affecting more than 100‚000 people in the United States alone each year (NIDDK‚ 2008). This paper will discuss the basic pathophysiology of acute renal failure‚ including its cause‚ disease mechanisms‚ symptoms‚ some of the treatments and pharmacological therapies. Pathophysiology Acute renal failure (ARF) is the rapid loss of kidney function occurring when high levels of uremic toxins accumulate in the blood

The ventricle will then contract shortly after the atria have started relaxing and followed by the closing of the atrioventricular valves‚ so blood does not back wash into the atrium. Pressure will becoming higher in the left ventricle allowing ventricular systole ’s second phase to begin by forcing blood through the aortic semi lunar valve up into the aorta so blood may reach the rest of the tissues in the body. Afterwards‚ the ventricles will becoming diastolic (relaxing) and pressure is now higher

Fluid and Electrolytes Imbalances Fluid Compartments: * Extracellular Fluid (ECF) – This is fluid found outside of the cells and the amount of ECF decreases with age. In the newborn for example‚ approximately ½ of the body fluid is contained in the ECF. By the time the infant has reached one year old; the ECF has decreased to approximately 1/3 of the total volume. In an average 70 kg adult the ECF is approximately 15 liters of total volume. ECF can further be divided into the following:
