CARDIO Tendon xanthomata: deposition of yellowish cholesterol rich material in the tendons‚ asociared with hyperlipidaemia. Eg on knuckles Xanthelasma: cholesterol deposits around the eyes. Corneal Arcus: deposition of cholesterol/lipid in the cornea. CRP : acute phase of protein produced predominantly by the liver in response to inflammatory cytokines Chest Pain on Xray: evidence of another cause of chest pain such as air in the mediastinum (oesophageal rupture) or aortic dissection

Then‚ we observed the wave patterns of the electrical impulses of the heart. We also identified the different intervals needed to be observed. Next‚ we interchanged the electrodes on the forearms with each other to be able to see a change in the electrical activity of the heart. Based on the results‚ all three subjects have normal QRS and Q-T intervals. On the other hand‚ Subject 3’s P-R value is not within the normal range‚ indicating his impulse might have taken a shorter route. Also‚ all three subjects

functions as the control center of the body‚ and it is in charge of the activities of the rest of the organs systems and the body’s components (Marieb‚ E.N. & Hoehn‚ K.). It helps the body communicate external environmental factors via electrical impulses that are transmitted through cells called neurons. These neurons can be up to a meter long and target a specific effector which it will help

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power‚ a transistor can amplify a signal. Today‚ some transistors are

Describe patient symptoms and conditions that could cause alterations in: Cardiac Output Volume of blood flowing through systemic or pulmonary circuit expressed in liters per min Normal= 5 L/min (resting adult) HRXSV= CO Factors: preload‚ afterload‚ myocardial contractility‚ heart rate As heart rate increases‚ this allows less time for diastole and the heart often cannot fill adequately. Therefore‚ a very rapid heart will often have

Nerve Conduction Study done on 10/17/15 demonstrated moderate carpal tunnel syndrome on the right side. Compared to his nerve conduction study from 2012‚ there was some worsening of the conduction. Treatment to date includes medications‚ PT‚ trigger finger injections‚ acupuncture‚ radial tunnel release in April 2015 and carpal tunnel release in August

arterial wall 3. Describe how the sympathetic and parasympathetic nervous systems work together to regulate the heart rate. a. The sympathetic and parasympathetic are two branches of the autonomic nervous system. Both supply nerve impulses to the heart. The sympathetic (fight or flight)‚ becomes more active when needed. Stimulation will increase the heart rate and force of contractions.
