53. What are catecholamine’s? - Hormones released by the adrenal medulla that play a key role in extrinsic control of myocardial functioning. Epinephrine and norepinephrine. Sympathetic response, critical in exercise. 54. Myocardial cells are… - highly aerobic and therefore high in myoglobin and mitochondria 55. The P Wave reflects… - Atrial depolarization as the impulse is initiated by the SA node and spreads throughout the atria 56. The PR Segment reflects… - The period of time where the impulse from the SA node is detected and continued by the AV node through the bundle of HIS and to the bundle branches 57. The QRS Segment… - Can reflect ischemia if depressed >1mm flat or downsloping 58. The T Wave… - can represent an acute infarction if inverted and coupled by an elevated ST segment 59. What is the most common EKG electrode placement system? Spell - Mason-Likar (12-lead) 60. Name the 12 leads… - 3 Standard Limb Leads (I II III), 3 Augmented limb leads (aVR, aVL, aVF), and 6 Precordial leads (V 1 to V 6 )

61. What view do these leads give? I – Right arm to left arm II – Right arm to left leg II – Left arm to left leg aVR – Left arm and left leg to right arm aVL – Right arm and left leg to left arm aVF – Right and left arm to left leg V 1 - V 6 - Left arm, right arm and left leg 62. T/F – In a second degree AV Block (MObitzl) we usually see elongated PR intervals, but followed by a QRS complex. - False 63. T/F – Premature ventricular contractions (PVS’s) can and will occur during exercise, and if they are not organized and or complex they are not a concern - True 64. What is Bigeminy? (also know how to spell) - Organized PVS’s occurring in a cycle where a normal beat is followed by a PVC, pause, normal beat, then PVC 65. What is Trigeminy? (also know how to spell) - normal beat, normal beat, PVC, pause, normal beat, normal beat, PVC, pause 66. What is ventricular tachycardia? - An arrhythmia that is basically a prolonged run of PVS;s that yield a very high HR of (150-250 bpm) 67. What is Wolff-Parkinson-White Syndrome? - An arrhythmia that is characterized by an abbreviated PR interval accompanied by a delta wave, and results from the intrinsic conduction from the atria to the ventricles going through the bundle of Kent instead of the

Bundle of HIS 68. How are bundle branch blocks usually detected? - By abnormalities in the QRS interval (elongated) 69. An inverted T-wave especially when seen with an elevated ST segment increased Q wave is reflective of… - An acute infarction 70. What is of least concern when determining a ST segment depression? - Segment is sloping up (upsloping) 71. What are the two parts of the traditional two- component model? - Fat mass and fat free mass 72. Obesity is related to… - Hyperlipidemia, Stroke, Pulmonary Dysfunction 73. Non-essential fat is found where? - On adipose tissue 74. What is the gold standard for body composition assessment? - Hydrostatic weighing 75. Accuracy of Bioelectrical Impedance Analysis (BIA) can be affected by… - Hydration Status, specific BIA equipment being used, ability of tester to correctly locate the anatomical sites where the electrodes are to be placed 76. Hydrodensitometry (underwater) weight is on the premise of what principle? Spell - Archimedes’ Principle

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
