telemetry exam 1Right atrium: oxygenated or deoxygenated? deoxygenated right ventricle: oxygenated or deoxygenated? deoxygenated Left atrium: oxygenated or deoxygenated? oxygenated left ventricle: oxygenated or deoxygenated? oxygenated pulmonary artery: oxygenated or deoxygenated? deoxygenated aortic arch: oxygenated or deoxygenated? oxygenated superior vena cava: oxygenated or deoxygenated? oxygenated inferior vena cava: oxygenated or deoxygenated? deoxygenated pulmonary vein: oxygenated or deoxygenated? oxygenated atrioventricular valves mitral and tricuspid what heart sound do the atrioventricular valves produce? makes S1 or "lub" semi-lunar valves pulmonary and aortic what heart sounds do the semi-lunar valves produce? S2 or "DUB" automaticity ability to make an impulse excitability ability to respond to an impulse conductivity ability to transmit energy from one cell to another what sets the rate for the heart and what is normal rate? determined by the fastest firing node SA node: 60-100 what node fires at a rate of 40-60? AV node what "pacemaker" fires the slowest? what are the norms for this node? ventricular: 30-40 identify 5 stage of action potential 1. rapid depolarization 2. early repolarization 3. plateau phase 4. rapid repolarization 5. resting phase
