Cardiac Telemetry Test with complete solution Normal Conduction System -SA Node = Primary Pacemaker of the Heart, rate of 60-100 bpm -Internodal Pathways = Pathways connecting SA Node and AV Node -AV Node = Backup pacemaker, rate of 40-60 bpm -Bundle of His = splits nerve fibers down Left & Right Sides, His-Purkinje is conduction system of heart -L & R Bundle Brancehs = lead to left & right of the myocardium -Purkinje Fibers / Network = ends of the muscle, last escape pacemaker sites ra...

What are the 6 parts of the cardiac conduction cycle? correct answer: -SA node -Internodal pathways -AV node -Bundle of His -R and L bundle branches -Purkinje fibers What is the SA node? correct answer: -Small cluster of cells located in the upper R atrium *-Pacemaker of the heart* What are internodal pathways? correct answer: Impulses sent by the SA node that travel through the atrial muscle fibers via the intra-atrial pathways Allows for simultaneous depolarization and contra...

Where are Beta 1 receptors found? - Correct Answer -Heart and Kidneys Stimulation of Beta 1 receptors result in an increase of what? - Correct Answer -Heart: Inotropy, Chronotropy, Dromotropy Kidneys: Renin-Angiotensin-Aldosterone System = Vasoconstriction = Increase blood pressure Which node is located at the junction of the superior vena cava and the right atrium, is typically supplied by the Right Coronary artery, and fires at a rate of 60-100 bpm. - Correct Answer -SA Node ...

what does each small box represent - .04 seconds what does 1 large box (5 small boxes) represent - .20 seconds what do 5 large boxes represent - 1 second primary pacemaker - SA node w/expected firing rat of 60-100 bpm backup pacemaker - AV node w/expected firing rate of 40-60 bpm final pacemaker - ventricles w/expected firing rate less than 40 bpm a normal PR interval is - .12-.20 seconds a normal QRS interval is - < .12 seconds (.04-.11) a normal QT interval is - .36-.44 seconds

Telemetry (Nursing 3270)Electrical - correct answer ____________ systole / diastole activation, excitation, depolarization recovery, recovery, repolarization mechanical - correct answer ______________ systole / diastole shortening, contraction, emptying lengthening, relaxation, filling Contractility - correct answer Force generated by the contracting myocardium under any given condition shorten and contract forcibly when stimulated by electricity Automaticity - correct an...

Normal Conduction System -ANSWER -SA Node = Primary Pacemaker of the Heart, rate of 60-100 bpm -Internodal Pathways = Pathways connecting SA Node and AV Node -AV Node = Backup pacemaker, rate of 40-60 bpm -Bundle of His = splits nerve fibers down Left & Right Sides, His-Purkinje is conduction system of heart -L & R Bundle Brancehs = lead to left & right of the myocardium -Purkinje Fibers / Network = ends of the muscle, last escape pacemaker sites rate of 14-40 Tele Strip Paper -ANSWER ...

cardiac electrophysiology correct answer: study of the electrical properties of the cardiac muscle -electricity flows through the heart in a regular, measured pattern and results in contraction of the cardiac muscle -electrical activity precedes mechanical activity (contraction of the heart) -EKG looks at the electrical activity properties of cardiac cells correct answer: specialized cardiac cells have unique characteristics that allow them to regulate heart rate and rhythm characteri...
