Cardiac conduction ECG components Heart auscultation All people enjoy time magazine Aortic, pulmonic, Erb's point, tricuspid, mitral P wave P wave= time for passage of the electrical impulse through the atrium causing atrial depolarization (contraction) Normal: 0.06-0.12 sec (remember, p for preteen: 6-12) What is a source of possible variation in P wave? disturbance in conduction w/in atria PR interval (PRI) -Measured from beginning of P wave to beginning of QRS comple...

Which of the following coenzymes is(are) necessary for normal red blood cell nuclear maturation and DNA synthesis pathway? A) Vitamin D B) Folate C) Calcium D) Vitamin B12 (cobalamin) E) Both folate and vitamin B12 (cobalamin) Ans: E Complexity: Easy Ahead: Hematopoietic System Subject: Chapter 3 Title: Hematopoietic Function 2. von Willebrand factor is directly involved ...

Telemetry med surg exam 3 Sinus node The intrinsic pacemaker. Cell membrane "leakiness" causes spontaneous depolarization at a rate of 60-100 times a minute. AV node Acts like a resistor to slow the impulse allowing time for the atria to completely contract before initiating ventricular contraction. Back up pacemaker if SA fails, pacing at a rate of 40-60 times a minute. Bundle of his "Cable" that passes through the fibrous sheath separating atria from ventricles. Divides into th...

ECG interpretation Correct Answer-(understand/know) ECG - rate calculation Correct Answer-(understand/know) P waves Correct Answer-represents time for atrial depolarization (contraction); should be upright; 0.06-0.12; disturbance indicates conduction problem within atria QRS interval Correct Answer-measured from beginning to end of QRS complex; represents time for ventricular depolarization (contraction); <0.12; disturbance indicates conduction problem in bundle branches or ventricle...

To determine whether there is a delay in impulse conduction through the ventricles, the nurse will measure the duration of the patient's: A) p wave B) q wave C) pr interval D) qrs complex D) qrs complex (the qrs complex represents ventricular depolarization. The p wave represents the depolarization of the atria. The pr interval represents depolarization of the atria, av node, bundle of his, bundle branches, and the purkinje fibers. The q wave is the first negative deflection following the...
