Telemetry Exam 62 Questions with Verified Answers ECG rhythm analysis - CORRECT ANSWER -determine if you have P waves -do the QRS complexes march out? -determine HR -interpret rhythm Normal sinus rhythm (NSR) - CORRECT ANSWER 60-100 Sinus Bradycardia potential causes - CORRECT ANSWER athletes, sleeping, medications, MIs, increased ICP, hypothermia Sinus Bradycardia symptoms - CORRECT ANSWER fatigue, dizziness, faint, chest pain, SOB, decreased cardiac output, pale, change in LOC, HR < 60 Medications that may cause sinus bradycardia - CORRECT ANSWER -anesthesia -beta blockers -digoxen Sinus bradycardia treatment - CORRECT ANSWER **Atropine (IV) -find cause of the bradycardia -O2 therapy -telemetry -notify provider -possibly dopamine or epinephrine drip What if Atropine doesn't work for sinus bradycardia? - CORRECT ANSWER pacer Sinus tachycardia potential causes - CORRECT ANSWER agitation, anxiety, fear, stress, exercise, pain, fever, caffeine, anemia, compensation for bradycardia Sinus tachycardia symptoms - CORRECT ANSWER palpitations, chest pain, SOB, dizzy Sinus tachycardia treatment - CORRECT ANSWER **depends on the cause -unknown cause: beta blocker -unstable (poor CO): cardioversion Cardioversion - CORRECT ANSWER -waits until it knows the heart rhythm -starts SA node -lower amount of energy required Premature Atrial Contraction (PAC) - CORRECT ANSWER -early beat -originates somewhere in the atria -may have different P wave PAC potential causes - CORRECT ANSWER caffeine (redbull, etc.), nicotine, hypoxia, stress, alcohol intoxication, electrolyte imbalance (K and Mg), COPD: rt hypoxia PAC symptoms - CORRECT ANSWER heart "skips a beat" PAC treatment - CORRECT ANSWER -**remove the cause -possible beta blockers if persistent Atrial Fibrillation - CORRECT ANSWER -originate from multiple ectopic foci in atria -P waves are difficult to find -QRS don't march out How common is atrial fibrilation? - CORRECT ANSWER fairly common-- many people live with a fib A fib potential causes - CORRECT ANSWER previous MI, heart disease, chronic alcoholic, electrolyte imbalances A fib treatment - CORRECT ANSWER -control HR (<100) -diltiazem (IV) -metrolpolol, digoxen -cardiovert them A fib and anticoagulants - CORRECT ANSWER if lasts more than 38 hours check for clot-- give anticoagulants first Atrial flutter - CORRECT ANSWER -ectopic focus: in atria -atrial impulses = 250 to 350 bpm -NO P wave Appearance of atrial flutter - CORRECT ANSWER "saw toothed" or "picket fence" appearance -only some impulses get through Atrial flutter potential causes - CORRECT ANSWER sick heart Atrial flutter treatment - CORRECT ANSWER -*treat underlying issue -ablation -cariovert Supraventricular tachycardia (SVT) potential causes - CORRECT ANSWER overexertion, stress, chronic disease, stimulants, born prone to it SVT symptoms - CORRECT ANSWER rapid HB, palpitations SVT treatment - CORRECT ANSWER *slam Adenosine 6 mg in fast -causes heart to go into asystole -need crash cart -return to normal rhythm -if it doesn't work, do another dose (12 mg) Heart blocks - CORRECT ANSWER -First degree -Second degree (Type I and II) -Third degree block First degree AV block - CORRECT ANSWER wide p-QRS interval -slow conduction First degree potential causes - CORRECT ANSWER sick heart, MI, CAD, electrolyte imbalance, meds First degree symptoms - CORRECT ANSWER usually asymptomatic First degree treatment - CORRECT ANSWER may be no treatment if no cause First degree AV block analogy - CORRECT ANSWER P wave = wife QRS = husband every night the husband comes home; but sometimes he's late Second degree AV block - CORRECT ANSWER wide and irregular p-QRS interval Second degree potential causes - CORRECT ANSWER sick heart, infection, clots, poor valves, drugs (beta blockers, digoxen) Second degree treatment - CORRECT ANSWER need a pacemaker Second degree Type I analogy - CORRECT ANSWER husband comes home at 6 one night, then 7, then 8, then he doesn't come home Second degree Type II analogy - CORRECT ANSWER husband comes home at 5 one night, spends 2 nights away, comes back for a night, leaves for 2 nights again Third degree block - CORRECT ANSWER complete heart block -the "atria and ventricles are functioning totally independently or dissociated from each other" Third degree symptoms - CORRECT ANSWER syncope Third degree treatment - CORRECT ANSWER pacemaker Third degree analogy - CORRECT ANSWER there is no association between the husband and wife; couple needs to start talking more for the sake of the kids Ventricular rhythms - CORRECT ANSWER Ventricle: primary pacemaker Dangerous! Ventricular rhythms rate - CORRECT ANSWER 20-40 bpm Ventricular rhythms QRS complex - CORRECT ANSWER 0.12 or greater (really wide) Ventricular rhythms T wave - CORRECT ANSWER opposite of QRS Premature Ventricular Complex (PVC) potential causes - CORRECT ANSWER alcohol use, stimulants, stress, hypoxia, electrolyte imbalance PVC symptoms - CORRECT ANSWER depends on the number of PVCs: "skips a beat", may not notice, bad cardiac output, chest pain PVC treatment - CORRECT ANSWER treat underlying cause -hypoxia: oxgen -stimulant: decrease amount -antidysrhythmic Ventricular fibrillation potential causes - CORRECT ANSWER electrolyte issues, sick heart, electrical shock Ventricular fibrillation symptoms - CORRECT ANSWER DEAD Ventricular fibrillation treatment - CORRECT ANSWER CPR, bagging, code cart, defibrillate, IV push epinephrine **all within first 2 minutes Two types of ventricular fibrillation - CORRECT ANSWER corse or fine Pulseless electrical activity (PEA) symptoms - CORRECT ANSWER VERY DEAD PEA treatment - CORRECT ANSWER -fix H's and T's -CPR -can't shock -epinephrine PEA - CORRECT ANSWER electrical and conduction goes through but no beat 5 T's - CORRECT ANSWER -drug toxicity -cardiac tamponade -thrombosis (PE or big MI) -tension pneumothorax -trauma 5 H's - CORRECT ANSWER -hypoxia -hyper/hypokalemia -hydrogen ion (acidosis) -hypothermia -hypovolemia Asystole "flat line" sypmtoms - CORRECT ANSWER VERY DEAD Asystole treatment - CORRECT ANSWER *outcomes bad -CPR, epinephrine -fix H's and T's Why should you never shock someone in asystole? - CORRECT ANSWER there is no electrical activity What happens if someone is in asystole for several minutes? - CORRECT ANSWER low chance of getting them back
