How many beats?
I will fix you
Name that drug (class)
Preload where?
100
Tall, narrow, peaked T waves
What is Hyperkalemia?
100
250-350 bpm (atrial rate)
What is atrial flutter
100
A pacemaker might be necessary if the patient is symptomatic
What is Mobitz I, 2nd degree
100
Na channel blockers; quinidine, procainamide
What is Class IA?
100
JVD, ascites, hepatic engorgement, peripheral edema?
What is Increased R ventricular preload?
200
Flat T wave, prominent U wave
What is HYPOkalemia
200
150-250 bpm
What is SVT?
200
Amiodarone, reduction of caffeine and stress and electrolyte replacement
What is PVC?
200
Calcium Channel Blockers; verapamil, cardizem
What is Class IV?
200
Dyspnea, cough, S3/S4 heart counds
What is Increased L ventricular preload?
300
Shortened QT interval?
What is Hypocalcemia?
300
> 350 (atrial rate, hard to count)
What is Atrial Fibrillation?
300
Amiodarone and cardioversion if I have a pulse; CPR and defibrillation if I don't
What is V-Tach?
300
Lidocaine; treats ventricular dysrhythmia
What is Class IB?
300
Possible S1/S2 muffling
What is decreased L ventricular preload?
400
Can cause complete AV heart block or cardiac arrest?
What is Hypermagnesemia?
400
HR < 60 bpm
What is sinus bradycardia?
400
CPR, defibrillation because I have no pulse and a chaotic waveform
What is V-Fib?
400
K+ channel blockers; amiodarone
What is Class III?
400
Flat jugular veins, dry mucous membranes, ortho-hypotension, poor skin turgor
What is decreased R ventricular preload?
500
Can trigger ventricular dysrhythmia (torsades de pointes)
What is Hypomagnesemia?
500
HR= 100-150
What is sinus tachycardia?
500
CPR due to complete absence of pulse and no electrical impulse present
What is asystole?
500
Na Channel Blockers; flecainide, propafenone
What is Class IC?
500
Too much fluid in the pulmonary circulation
What is increased preload in the L side of the heart?
