Masters of Rhythm
Regularity, Rate, P wave?, Conduction PR Interval, QRS
What are the 5 key elements for rhythm interpretation?
Sinus Brady has this originates in which pacemaker node?
What is the SA node?
Type of electrical current that can be used to speed up or slow down a heart rate, often causes "twitching" if used externally
What is pacing?
This drug can be oral or IV and is used to slow the ventricular rate in rapid Atrial fibrillation or Atrial flutter.
What is Diltiazem (Cardizem)
Look at the underlying cause for treatment.
What is sinus tachycardia?
Ischemia, electrolyte imbalances, medications such as antiarrhythmics, antipsychotics, antihistamines, and antidepressants contribute to me..
What is a prolonged QTc?
Often dances around the SA node, causing increased automaticity in the atrial fibers
Shock me if I am unstable and I may convert. I am fast with narrow complex QRS. I do not have p waves, and sometimes I start and stop abruptly.
What is supraventricular tachycardia?
Treat me with atropine or a pacemaker if I am slow.
What is a bradycardia?
Rate control, antithrombotic therapy, and correct rhythm are the 3 priorities for treatment of this rhythm.
What is Atrial Fibrillation?
Often related to respirations, speeds up with inhalation and slows down with exhalation
What is sinus arrythmia?
With a fast atrial rhythm, this node blocks some of the impulses getting to the ventricles.
What is the AV Node
I twist and turn and if I do not have a pulse the best treatment is...
What is defibrillation.
If I am stable, treat me with vagal maneuvers, adenosine to slow me down
What is Supraventricular Tachycardia?
Acute MI, untreated VT, electrolyte imbalances, hypokalemia, hyperkalemia, acid-base imbalance, R on T, drug overdose
What are causes for Ventricular Fibrillation?
I have a pacemaker spike before each atrial contraction (P wave)
SA Node is not working, the AV node is firing, the rhythm sometimes has a P wave, but may be inverted, before, during or after the QRS. It can be fast or slow.
What is a Junctional Rhythm?
No cardiac output or pulse. I am erratic, can be fine or course. The best treatment is to shock me.
What is Ventricular Fibrillation?
Amiodarone, Beta Blockers, and Calcium Channel blockers are medications that are used to surpress me.
What are PVCs?
MI, pacemaker failure, metabolic imbalance, myocardial ischemia are causes of this rhythm. I still have a beat, but I am slow with wide complexed QRS.
What is idioventricular rhythm?
My rate is 101-250, without P waves and wide bizarre QRS complexes. Sometimes I have retrograde P waves.
What is V tach?
The SA node and AV node are blocked, so the next pacemaker is
What is the ventricle, or Purkinje fibers?
I can have a beautiful conduction, but no electrical or mechanical conduction.
What is Pulseless Electrical Activity?
I am caused by side effects of different drugs, that prolong my QTc. As I twist and turn, and have a pulse, I can be treated with?
What is IV magnesium?
Failure to sense or failure to capture, lead dislodgment, battery failure.
What are causes of pacemaker malfunction?
