The cardiac conduction system of the heart consists of specialized muscle cells that generate and send rhythmic electrical impulses to the myocardium in order for the heart to contract (Cardiac Conduction System‚ 2016). When there is the normal rhythm of the heart it is called sinus rhythm and any deviation from sinus rhythm is called an arrhythmia (Saladin‚ 2012). Electrocardiograms (ECG) record the electrical impulses and help determine when there are any abnormalities in the way the heart functions

CONGESTIVE CARDIAC FAILURE Congestive cardiac failure is defined as “the state in which the heart is unable to pump blood at a rate adequate for supplying the requirements of the tissues with function parameters remaining within normal limits usually accompanied by effort intolerance‚ fluid retention and reduced longevity” (Denolin‚ 1983‚ p. 445). Congestive cardiac failure or heart failure continues to be a major public health issue worldwide. This paper is a case study report about C.B‚ a 60

Cardiac surgeons are people who do treatments and surgeries to treat people with heart and lung disease. They also deal with vessels and organs. There are a lot of different types of operations. There is heart valve repair and replacements‚ heart defect repair‚ coronary artery bypass‚ aneurysm repair‚ heart transplant‚ lungs (lung disease). They complete the most surgeries in their field. Grey’s Anatomy influenced me because in that show it’s a bunch of different types of surgeons and I liked cardio

• Cardiac hypertrophy- This is when the heart increases in size and volume‚ the wall of the left ventricle will get thicker with the help of constant exercise‚ this leads to an increased force of contraction. This will allow the heart to pump out a larger amount of blood with each pump‚ therefore a more efficient heart as it will not have to beat as many times as an untrained heart. • Increase in stroke volume and cardiac output- Stroke volume is defined as the amount of blood the heart is able to

this experiment was to examine how the compound action potentials propagate down the sciatic nerve of a frog based on varying stimuli. Before the nerve could be tested it needed to be extracted from the thigh of the frog and then submerged in saline. Several varying stimuli were used and recorded by a software package. The second experiment requires a constant stimulus with varying reference pin locations. From this the velocity of the action potential propagated can be determined. The experiment revealed
