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...

aneurysm visible, prominent pulsation or dialation diastole ventricular relaxation, ventricular filling from atria. erythema redness of skin murmur harsh, blowing sounds caused by disruption of blood flow myocardial ischemia oxygen needs heightened so heart has to work harder systole ventricular contraction, blood leaves the ventricles to go to the lungs or body. what is the pacemaker of the heart sinoatrial node (SA node) how many times is the sinoatrial node set to discharge per ...

Where and why are lumbar punctures performed? - Answer- Spinal Block -> Anesthetic (into epidural space) Spinal Tap -> CSF extraction (into subarachnoid space)W B/W L3/L4 or L4/L5 NB: Posterior to this is *cauda equina* Where does a *herniated intervertebral* disk occur? What causes it? - Answer- Occurs b/w L4/L5 or *L5/S1* and C5/C6 or C6/C7 NB: affects lower spinal nerve # Degeneration of annulus fibrosis followed by *sudden compression* of nucleus pulposus What is the dif...

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...
