Chapter 02: Introduction to the 12-Lead ECG TRUE/FALSE 1. The point where the QRS complex and ST segment meet is called the ST-junction or J-po ANS: T The point where the QRS complex and the ST segment meet is called the ST-junction or J-point. OBJ: Identify the J-point and ST-segment deviations. 2. If the wave of depolarization (electrical impulse) moves toward the positive electrode, the waveform recorded on ECG graph paper will be upright (positive deflection). ANS: T If the wave of...

You're using anion exchange chromatography to purify a small globular protein. After passing the mixture through the column, you find that your protein did not "stick" to the resin and flowed right through. What is a plausible reason for this to have occurred? Correct Answer-The pH of the solution is close to the isoelectric point. Oxygen binding that affects the cooperatively of hemoglobin is an example of heterotrophic regulation. Correct Answer-False You have determined that a leucin...

Princeton Review MCAT Practice Test Questions| 100% Correct Answers Sickle-cell anemia (HbS) results from a substitution to valine from glutamic acid at position 6 of the β chain of hemoglobin. Which of the following best explains why the isoelectric point of HbS is higher than that of HbA? A. The side chain of glutamic acid is less acidic than that of valine. B. Glutamic acid is isoelectric at a lower pH than is valine. C. Valine is isoelectric at a lower pH than is glutamic acid. D. G...

(in the correct order away from the alpha) correct answers Beta, gamma, delta What is the pI? correct answers Isoelectric point of the Amino Acid titration curve What is the point of the Amino Acid curve? correct answers To ta...

Electrocardiogram (ECG) - Since you can't see the heart beating we use a ECG to provide a picture that replicates the actual cardiac issue. Myocardial Infraction (MI) - Heart Attack -Have abnormal rhythms. -Death of cardiac muscle due to ischemia Doe the ECG machine monitor or control the hearts rhythm? - Only monitors Straight line when machine is turned on but not connected to the patient - Isoelectric = no current It is straight because there is a balanced electrical force field. Thi...

P wave - Answer Usually round & upright 0.06 to 0.12 seconds QRS complex - Answer normal duration 0.4 to 0.10 (one small box to 2.5 small boxes) PR interval - Answer normal duration 0.12 to 0.20 ST segment - Answer should be isoelectric the "J point" should come back to baseline 10 times method - Answer count the number of R waves in a 6 second strip and multiply by 10 Big block method - Answer Divide the number of big boxes between 2 consecutive R waves into 300 ...
