Dysrhythmias with Pictures correctly answered 2023

Dysrhythmias with Pictures correctly answered 2023Sinus Bradycardia Treat with atropine if experiencing hypotension, angina, or LOC Pacemaker Name this rhythm. What do you treat with and why? What do you treat with if prolonged and patient is symptomatic? Sinus Tachycardia Fast HR 100-150 Treat underlying cause Name this rhythm. What is the only problem with this rhythm? What is the best treatment? Atrial Fibrillation Treat by underlying cause Anti-coagulate therapy BLOOD THINNER R to R is irregular ALL Have abnormal P waves Risk for clots, PE, thrombolytic stroke due to decreased stroke volume because you don't have enough time for depolarization and relaxation Name this rhythm. What is the best way to treat? What else do you treat? How is the R-R interval? Are P waves normal or abnormal? What are you worried about with this rhythm and why? Atrial Flutter Saw-toothed Cardioversion is best treatment Put pt on beta blockers, CCBs, adenosine, digitalis Name this rhythm. What is the shape of this rhythm? Best treatment? What does nurse do if they cannot convert this rhythm to normal sinus rhythm? Supraventricular Tachycardia Regular rhythm NO P WAVES (T wave takes over P wave) QRS normal because origin above ventricles Valsalva's maneuver 1st BEFORE meds Carotid massage before meds May need cardioversion to correct dysrhythmia Name this rhythm. Is this rhythm regular or irregular? Does this rhythm have P waves? Is the QRS normal or abnormal and why? What is treatment to be taken BEFORE meds? What about if pt is in extreme distress and meds are not working? Premature Atrial Complex Stimulus other than SA node fires too early Harmless unless person has existing CV disease Name this rhythm. What happens with the stimulus in this rhythm? Is this harmful? Junctional Dysrhythmia Digitalis toxicity Because the firing is coming from the AV, not SA node Because of low HR from firing from AV Get up slowly Hold medication that caused rhythm and treat with atropine or pacemaker insertion Name this rhythm. What precipitates this rhythm? Why wont you see a P wave? Why does the pt have to be watched for low O2? What should the nurse advise the patient to do? What should we do to treat? Accelerated Junctional Dysrhythmia Name this rhythm. Premature Ventricular Contraction w/ complete pause Bigeminy - normal complex, PVC, normal complex, PVC, etc. Trigeminy - normal complex, normal complex, PCV, normal complex, normal complex, PVC, etc. Become v tach w/ 3 OR MORE! Supplemental oxygen DOC - amiodarone Name this rhythm. Differentiate between the different types of this rhythm. When do these become V tach? How can this be corrected? What is the DOC if frequent or symptomatic? Unifocal PVC Name this rhythm. Multifocal PVC Name this rhythm. Ventricular Tachycardia Can lead to V fib Treatment with a pulse is synchronized cardioversion Treatment with NO pulse is CPR and defibrillation Name this rhythm. What can this lead to? What is the tx w/ pulse? What is the treatment w/ NO pulse? Ventricular Fibrillation (FATAL) CPR b/c heart is not circulating anything there De-fib, epinephrine, vasopressin Name this rhythm. What is the treatment? V tachy --> V fib (FATAL) What can consecutive PCVs lead to? Asystole Verify with 2 leads because fine V-fib can look like asystole on strip De-fib wont work because there is no rhythm to synchronize Start with CPR and med (epinephrine/vasopressin) Fix underlying cause (best approach) Usually terminal rhythm at this point What must you verify this rhythm with and why? Treatment? Why wont defribillation work? 1st Degree AV Block Delay in conduction in AV node but fires normally from SA node Prolonged PR interval Usually benign unless with CV disease or MI --> 2nd & 3rd degree blocks Name this rhythm. What happens in conduction/impulses? What happens to PR interval? Is this harmful? 2nd Degree - Type 1 Wenkebach (Mobitz Type 1) Starts normal but PR interval lengthens and eventually drops QRS complex, longer longer til it drops and now you have Wenkebach Usually considered benign If symptomatic, treat Name this rhythm. What happens to the PR interval and QRS complex here? Is this harmful? When do you treat?
