Choose the term that does NOT belong in each of the following groups. A B C D 1 Pulmonary Trunk Vena Cava Right Side of the Heart Left Side of the Heart 2 QRS Wave T Wave P Wave Electrical Activity of the Ventricles 3 AV Valves Closed AV Valves Opened Ventricular Systole Semilunar Valves Open 4 Tricuspid Valve Mitral Valve Bicuspid Valve Left AV Valve 5 Pulmonary Valve Umbilical Artery Pulmonary Vein Superior Vena Cava
Identify if the statements are TRUE or FALSE. TRUE FALSE STATEMENTS When the atrioventricular bundle is completely interrupted, the ventricles typically contract at 30 to 40 beats/minute. The left ventricular wall of the heart is thicker than the right wall in order to pump blood with a greater pressure. Impulses through the conduction system of the heart follow the ordered path SA Node ->Conduction Myofibers ->AV Bundle ->AV Node.

The standard EKG consists of 10 sensors that record 12 leads of the heart’s electrical activity from different angles, allowing for a thorough three-dimensional interpretation of its activity. This is transmitted by the electrodes to the equipment to be interpreted and is used to diagnose cardiac medical conditions. In case of an abnormal EKG, the second step would be to use a Holter monitor. How would you explain how to perform an EKG (steps)? Where will you place the electrodes when performing and EKG? Why? What are the different lead types, connections, and placements? When you conclude an EKG, what are the different components that you need to observe and confirm before you disconnect the patient? Can you explain the difference between normal, abnormal, and artifacts? What is a Holter monitor? Under what circumstances would one be ordered for a patient? How do you use a Holter monitor? Educate a patient: What you will do before, during, and after an electrocardiogram or…
