Q

START to finish Bradycardia Algorithm

A

Bradycardia: Heart rate typically less than 50 BPM if bradyarrhythmia, (identify and treat underlying cause) ABC, cardiac monitor, IV access. 12 lead if available. Don’t delay therapy for a 12 lead. Is Bradycardia causing Hypotension? AMS? Signs of shock? Ischemic chest discomfort? Acute heart failure? NO=Stable=monitor and consider giving atropine/Dopamine infusion or Epinephrine infusion. YES=Unstable=Pace the patient. If unable to capture and medication interventions haven’t been made, consider using this. Dopamine drip will be the most effective.

Premature Atrial Contraction
27
How do your P-waves look with a PAC?
Present, but the one itself will look different than all the other P-waves.
28
PR interval with a PAC.
PR Interval can be normal or slightly short. It'll stand out from all the others as if it doesn't belong.
29
What does the QRS in a PAC look like? What rhythm do you see?
Narrow and upright. Irregular.

A-Flutter
32
What is a PJC?
Premature Junctional Contraction
33
What does the P-wave and QRS look like in a PJC?
P-wave's are typically absent or inverted. QRS is positive and narrow.
34
What is a PVC? What is it mainly caused by?
Premature ventricular contraction caused by Hypoxia
35
P wave identifiers for a PVC, QRS. What are some different ways to identify a PVC?

37
What is the typical rate you'll see with a MAT? Rhythm? What kind of P-waves will you see?
Exceeding 100 BPM. You see an irregular rhythm and you're going to see different P-waves because you have multiple focai firing causing difference in P waves.

39
What type of rhythm do you see? What rate? What kind of P-waves? QRS? What is an important identified for this?
You see an irregular rhythm. At a rate of 60-100 BPM. P-waves have an abnormal morphology (3 or more different looking P-waves) because they're all originating from different Atrial sources. QRS is upright and narrow.

45
A 75 year old male complains of weakness and fatigue. He has dependent edema and jugular vein distension. Last year, he had three cardiac stents placed. What should you suspect?
Right Ventricular heart failure
46
What does a P-wave represent and what is the normal duration for it?
P-waves represent Atrial depolarization (contraction) and should be 0.10 seconds or less
47
What does the PR interval represent and what is it's duration?
PR interval represents the time required for the electrical impulse to be conducted through the AV node. This is where you have your Atrial kick. PR interval duration should be 0.12-0.20 seconds. Anything exceeding 0.20 seconds is a 1st degree block
48
What does the QRS represent and what is it's duration?
QRS represents ventricular depolarization and it's duration is 0.08-0.12. More than 3 small squares is a widened QRS which could be a LBBB
49
ST segment. What is represents?
ST segment represents the early phase of repolarization in the left and right ventricles. This is where you're going to look for any ST depression or elevation. Elevation is classified as more than 2 small squares high.
50
T waves. What they represent and their duration?
T-waves represent ventricular repolarization. Normally the duration is 4 small boxes. Keep in mind that heightened T-waves represent hyperkalemia.
51
Chronotropic
Heart Rate
52
Amiodarone (Class, MOA, Indic., Contra., side effects, dosages)
Antidysrhythmic, MOA-Blocks sodium, potassium, and calcium channels, prolongs action potential and repolarization, decreases AV and SA node function. Indications: V-tach with a pulse, cardiac arrest (pulseless v-tach/v-fib), stable, regular narrow complex tachycardia following failure to convert from vagal maneuvers or adenosine. Contraindications: Cardiogenic shock, 2nd or 3rd degree AV block, sick sinus syndrome. Side Effects: ARDS, pulmonary edema, dyspnea, heart failure, bradycardia, hypotension, prolonged QT interval, burning at IV site. Dosage: Adult v-fib or pulseless v-tach: 300mg IVP followed by 150mg IVP after 3-5 minutes. Wide complex tachycardia: 150mg in 100ml over 10 minutes Pediatric v-fib or pulseless v-tach: 5mg/kg IVP, repeat once in 3-5 minutes Duration: 30min-2hrs, peak-3-7hrs
53
Identifiers of a 1st degree block
Prolonged PR-interval of more than 0.20 seconds. Consistent all the way through.
54
Identifiers of a 2nd degree type 1 block. Or a Mobitz 1.
"Longer, longer, longer, drop. Now we have wenckebach" PR interval keeps getting longer and longer until there is a p-wave not followed by a QRS.
55
Identifiers of a 2nd degree type 2 block. Or a Mobitz 2.
"If some P's don't get through, now we have mobitz 2" Your P-waves are consistent but you have a dropped beat. P-wave that is not followed by a QRS.
56
Identifiers of a third degree block. Complete heart block.
Your P-P intervals and R-R intervals are consistent. P's are not married to QRS.
