ECG Basics
This interval represents the time from atrial depolarization to ventricular depolarization
What is the PR interval?
This rhythm has no identifiable P waves and is “irregularly irregular”
What is atrial fibrillation?
This medication is commonly used to slow the ventricular rate in atrial fibrillation
What is diltiazem (Cardizem)?
The first action the nurse should take when a patient becomes bradycardic
What is assess the patient (ABCs)?
This rhythm has no pulse and requires immediate defibrillation
What is ventricular fibrillation?
The normal duration range for a QRS complex
What is < 0.12 seconds
This rhythm has a sawtooth pattern on an ECG
What is atrial flutter?
This is the first line drug for symptomatic bradycardia
What is atropine?
This is a priority action for stable ventricular tachycardia
What is vagal maneuvers?
This is a pulseless rhythm with organized electrical activity
What is pulseless electrical activity (PEA)?
This wave represents ventricular depolarization
What is the QRS complex?
A wide complex, regular rhythm with no P waves; patient may or may not have a pulse
What is ventricular tachycardia?
This is an antiarrhythmic medication commonly used for ventricular dysrhythmias
What is amiodarone?
The is the treatment for unstable tachycardia with a pulse
What is synchronized cardioversion?
These are 2 interventions for a patient in asystole
What is high-quality CPR and epinephrine?
The normal range for heart rate
What is 60-100 beats per minute?
This rhythm has PR interval prolongation that becomes progressively longer until a beat is dropped
What is a secondary AV block Type 1 (Wenckebach)?
This is the first line medication used to treat Torsades de Pointes
What is magnesium sulfate?
This is the priority intervention for symptomatic complete heart block
What is transcutaneous pacing?
This rhythm appears as a flat line and does not produce a palpable pulse
What is asystole?
This interval represents ventricular depolarization and repolarization
What is the QT interval?
In this rhythm, there is no consistent relationship between the P waves and the QRS complexes
What is a 3rd degree heart block (complete heart block)?
This medication is given every 3-5 minutes during cardiac arrest
What is epinpehrine?
After determining there is no pulse, this is the immediate action to treat a patient goes in ventricular fibrillation
What is defibrillation?
This is a polymorphic ventricular tachycardia associated with a prolonger QT interval
What is Torsades de Pointes?
