Congenital Heart Disease Congenital heart disease is the classification of heart disease in which the defect of the heart is present at birth. An estimated minimum of 32,000 infants, or 8:1000 births, are expected to be affected every year in the United States. Approximately twenty five percent...
Congestive Heart Failure Investigated Disease Process The disease process that will be examined in this essay is congested heart failure. According to the U.S National Library of Medicine, congested heart failure (CHF) is “a chronic condition in which the heart cannot pump blood properly”, leading...
The heart is the only specialized organ that is made of cardiac muscle. It has heart cells called cardiomyocytes that make up muscle fiber and conduct electrical impulse. The heart has four chambers. The upper which are called the atria and the lower called ventricles and are separated left and right...
patients in the United States (U.S.) is heart failure (HF), accounting for more than one million hospitalizations a year (Paul & Hice, 2014). In 2006 the American Heart Association (AHA) estimated 5.1 million people in the U.S. were diagnosed with heart failure(HF), in 2014 they estimated 6.8 million...
oxygen, the alveoli sits against the capillaries where the deoxygenated blood has been picked up from tissue around the body and carried away from the heart via the pulmonary artery to be then transported to the lungs. The alveoli and capillaries both have thin cell walls allowing diffusion to take place...
artificial heart valve is a device which is implanted in the heart of patients who suffer from valvular diseases in their heart. When one or two of the four heart valves of the heart have a malfunction, the choice is normally to replace the natural valve with an artificial valve. This requires open-heart surgery...
CYCLE It is the sequence of events which make up one heart beat. Contraction is called systole and relaxation is called diastole. SYSTOLE Atrial Systole Heart muscle in atrial walls contract simultaneously. Blood is conveyed into the ventricles. Backflow of blood into vena cava and pulmonary veins...
Dilated cardiomyopathy is a condition strongly related to heart attacks, in which the ventricles are enlarged, resulting in a thinning of cardiac walls, and insufficient pumping of blood. Dilated cardiomyopathy can occur at any age, though it is most common in the 20-40 demographic. One of the major...
Automaticity refers to the hearts ability to generate its own intrinsic electrical rhythm. Barorecptors pressure-sensitive nerve endings in the walls of the atria of the heart, the vena cava, the aortic arch, and the carotid sinus. Cardiac Output volume of blood pumped per minute by the heart. Cardiac Tamponade...
The heart is bestowed with a specialized system that automatically generates rhythmic control via the sinus node, located in the superior lateral wall of the right atrium near the opening of the superior vena cava. The specialized pacemaker cells dictate control of the rest of the heart through ...
Heart failure is a weakening of the heart's pumping power. With heart failure, your body doesn't get enough oxygen and nutrients to meet its needs. These measures show some of the recommended treatments provided for most adults with heart failure. When dealing with heart failure patients there are...
the heart's lower left chamber (ventricle) into the aorta and to the body. Stenosis prevents the valve from opening properly, forcing the heart to work harder to pump blood through the valve. This causes pressure to build up in the left ventricle and thickens the heart muscle. Your heart can make up for...
it affects the body, we must first understand how the human heart works. The human heart is very complex and is essential to life. Wolff-Parkinson-White syndrome is when there is a presence of an extra abnormal electrical pathway in the heart that leads to a fast heartbeat. It has a few symptoms, but...
right atrium of the heart via (Pauline Lowrie, 2008) the vena cava and passes into the right ventricle and gets pumped to the lungs through the pulmonary artery. Oxygenated (Pauline Lowrie, 2008) blood comes from the lungs via the left atrium of the heart into the left ventricle and it gets pumped to...
venous blood to the heart. Veins carry blood back to the heart. In veins are found valves, thin folds of tunica interna that form flap like cusps. The valve cusps project into the lumen, pointing toward the heart. The low blood pressure in veins allows blood returning to the heart to slow and even back...

has long been known that its importance varies considerably among populations, across space and through time. In 2004, the death rate from ischaemic heart disease (IHD) among those under 65 was almost twice as high in the UK as in Spain, yet in 1970 it had been five times higher. During the 1990s, when...

Pathway of the Heart? 1. Deoxy generated blood enters the right atrium through the superior and inferior vena cava. 2.
