EKG Review
This wave represents atrial depolarization.
What is the P wave?
This dysrhythmia is characterized by an irregularly irregular rhythm and absence of identifiable P waves.
What is atrial fibrillation?
This disorder occurs when the heart cannot pump enough blood to meet the body's demands.
What is heart failure?
This vascular disorder occurs when blood flow to the legs is reduced due to atherosclerosis.
What is peripheral arterial disease (PAD)?
A patient with chest pain arrives in the ED. What laboratory value is most important to assess for myocardial injury?
What is troponin?
This interval normally measures 0.12-0.20 seconds and reflects AV node conduction.
What is the PR interval?
This rhythm is commonly described as "sawtooth" flutter waves.
What is atrial flutter?
Crushing chest pain that occurs because of decreased blood flow to the myocardium is called this.
What is angina?
Pain in the calves during walking that is relieved by rest is called this.
What is intermittent claudication?
A patient with atrial fibrillation is at increased risk for developing this complication.
What is a stroke?
This complex represents ventricular depolarization.
What is the QRS complex?
A heart rate less than 60 bpm is known as this rhythm.
What is sinus bradycardia?
Elevated ST segments on an EKG may indicate this cardiac emergency.
What is myocardial infarction (MI)?
Warm skin, edema, and brown discoloration of the lower legs are signs of this disorder.
What is chronic venous insufficiency?
Which patient should the nurse assess first: a patient with stable angina or a patient with chest pain unrelieved by nitroglycerin?
Who is the patient with chest pain unrelieved by nitroglycerin
A normal sinus rhythm has a heart rate within this range.
What is 60-100 beats/minute?
This life-threatening rhythm appears as chaotic ventricular activity with no cardiac output.
What is ventricular fibrillation?
This laboratory marker is considered highly specific for myocardial damage.
What is troponin?
The nurse suspects this condition when a patient reports unilateral leg swelling, pain, and redness.
What is deep vein thrombosis (DVT)?
The priority nursing action for a patient experiencing ventricular fibrillation is this.
What is initiate CPR and prepare for defibrillation?
This wave represents ventricular repolarization.
What is the T wave?
The first treatment for a pulseless ventricular tachycardia patient is this intervention.
What is defibrillation?
Chest pain relieved by rest or nitroglycerin is associated with this condition.
What is stable angina?
This life-threatening complication can occur when a DVT breaks loose and travels to the lungs.
What is a pulmonary embolism (PE)?
A patient with heart failure gains 4 pounds in 2 days and develops increasing shortness of breath. This finding suggests worsening what?
What is fluid overload/heart failure exacerbation?
This dysrhythmia has no pulse, no organized electrical activity, and is commonly called a "flatline."
What is asystole?
A patient's EKG shows:
Identify the rhythm and one major complication.
