Dysrhythmias/CA

QuestionAnswer
A-fib No P waves or PR interval, atria quivering
A-fib medication Amiodarone, metoprolol, digoxin, heparin
A-fib, A-flutter treatment Medication, cardioversion, catheter (radiofrequency) ablation, maze procedure with cryoablation
Cardioversion Shock to reset heart to normal rhythm, synchronized to shock on R. Maintain airway (sedated). Informed consent
Catheter (Radiofrequency) ablation Heat destroys or shrinks abnormal tissue
Maze procedure with cryoablation Cold energy to create scar tissue pattern in heart
Amiodarone Treats and prevent arrythmias Monitor BP, ECG, signs of heart failure
Second degree block, type 1 (Mobitz 1/Wenckebach) "If PR gets longer, then a QRS dop" Can be due to ischemia, drugs
Wenckebach treatment Symptomatic = Atropine + pacemaker Asymptomatic = Monitor
Second degree block, type 2 (Mobitz 2) "If PR stays normal, and QRS quits" Can be due to heart disease, drug toxicity
Mobitz 2 treatment Pacemaker
Third degree block Normal P wave, no connection with QRS complex Low heart rate <40bpm
Third degree block treatment Transcutaneous pacing or permanent pacemaker. Dopamine and epinephrine to increase HR while waiting for procedure
Premature ventricular contraction/depolarization Can cause more serious dysrhythmias, assess hemodynamic status, no shower for 1-2 days, Holter Monitor
Holter Monitor Portable ECG, to measure over a period of time
V-Tach Looks like a saw, patient is hypotensive Stable = pulse Unstable = pulseless
V-Tach treatment Stable = amiodarone, cardioversion Unstable = CPR, defibrillation
V- Tach Torsades de Pointes Polymorphic, treatment is needed or can turn into V-fib
Torsades de Pointes treatment Magnesium Sulfate
V-Fib Patient is unconscious, if not treated rapidly death will result
V-Fib treatment D-fib, CPR, amiodarone 300mg push
Asystole (flat line) treatment CPR, epinephrine, intubation
ICD (implantable cardioverter defibrillator) Monitors the heart rhythm and delivers an electrical shock if it detects a life-threatening arrhythmia
Pacemaker Monitors the heart rhythm and sends electrical pulses to regulate it when it beats too slowly

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
