42 Aero Camino, Goleta, CA 93117 Biopac Student Lab ® Lesson 5 ELECTROCARDIOGRAPHY (ECG) I Procedure Rev. 12292017 Richard Pflanzer, Ph.D. Associate Professor Emeritus Indiana University School of Medicine Purdue University School of Science William McMullen Vice President, BIOPAC Systems, Inc. Page P-1 ©BIOPAC Systems, Inc. II. EXPERIMENTAL OBJECTIVES 1) To become familiar with the electrocardiograph as a primary tool for evaluating electrical events within the heart. 2) To correlate electrical events as displayed on the ECG with the mechanical events that occur during the cardiac cycle. 3) To observe rate and rhythm changes in the ECG associated with body position and breathing. III. MATERIALS BIOPAC Electrode Lead Set (SS2L) BIOPAC Disposable Electrodes (EL503,) 3 electrodes per subject BIOPAC Electrode Gel (GEL1) and Abrasive Pad (ELPAD) Optional: BIOPAC Skin Prep Gel (ELPREP) or alcohol prep Mat, cot or lab table and pillow for Supine position Biopac Student Lab System: BSL 4 software, MP36, MP35 or MP45 hardware Computer System (Windows or Mac) IV. EXPERIMENTAL METHODS A. SETUP FAST TRACK Setup Detailed Explanation of Setup Steps 1. Turn the computer ON. If using an MP36/35 unit, turn it OFF . If using an MP45, make sure USB cable is connected and ! Ready " light is ON . 2. Plug the equipment in as follows: Electrode Lead Set (SS2L) # CH 1 3. Turn ON the MP36/35 unit. Fig. 5.5 MP3X (top) and MP45 (bottom) hardware connections 4. Clean and abrade skin. 5. Attach three electrodes on Subject as shown in Fig. 5.6. Setup continues « Clean electrode sites with ELPREP Skin Prep Gel or alcohol before abrading. Always apply a drop of gel (GEL1) to the sponge portion of electrodes before attaching. Remove any jewelry on or near the electrode sites. Place one electrode on the medial surface of each leg, just above the ankle . Place the third electrode on the right anterior forearm at the wrist (same side of arm as the palm of hand). For optimal electrode contact, place electrodes on skin at least 5 minutes before start of Calibration.

RIGHT forearm = WHITE lead RIGHT leg = BLACK lead (ground) LEFT leg = RED lead Fig. 5.6 Lead II Setup The pinch connectors work like a small clothespin, but will only latch onto the nipple of the electrode from one side of the connector. 7. Subject gets in supine position (lying down, face up) and relaxes (Fig. 5.7). Position the electrode cables so that they are not pulling on the electrodes. Connect the electrode cable clip to a convenient location on Subject s clothes. Fig. 5.7 Positioning (supine) 8. Start the BIOPAC Student Lab program. 9. Choose lesson !

    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.
