Incidence and Prevalence of Arrhythmias and HF
Cardiac Arrhythmia
Types of Arrhythmias
HF
100
improved cardiac output cardiac output with an elimination of symptoms.
What is compensated
100
True/False HF is the most common Mediace diagnosis-related group, and more Medicate dollars are spent of rat diagnosis and treatment of HF that for any other clinical entity.
What is true. page 81
100
What is characterized by phasic variation in sinus cycle length?
sinus arrhythmia
100
slow heart rate
What is bradycardia
100
true or false If a patient is becoming hypotensive a supine position is well tolerated.
What is false should not be in the supine position.
200
Symptomatic HF.
What is decompensated
200
_______ are relatively common in the general population; their prevalence increases with age.
What is cardiac arrhythmias. page 67
200
Heart rate greater than 100 beats per minute in an adult, with otherwise normal findings.
What is tachycardia
200
heart does not beat properly
What is conduction disorders
200
True/false Heart failure means that the heart isn't pumping at all and nothing can be done.
What is false. Actually, heart failure means that the heart isn't pumping as well as it should be.
300
The time after a normal impulse is generated, SA nodes need time for recovery and repolarization, during this time they cannot conduct an impulse.
What is Refractory.
300
In the U.S. approximately how many deaths are primarily caused by HF?
56,000
300
What are lethal arrhythmias characterized by chaotic, disorganized electrical activity that results in failure of sequential cardiac contraction and inability o maintain cardiac output
What is Ventricular flutter and fibrillation
300
early heart rate
What is premature contraction
300
Right ventricular failure results in systemic venous congestion may include the presence of what?
What is distended neck veins, large tender liver, peripheral edema, and ascites. Occasionally, patients with HF may exhibit clubbing of the fingers.
400
have “local anesthetic” properties or membrane-stabilizing effects and work by primarily blocking the fast sodium channels.
What is class I drugs.
400
What is the most common underlying cause of HF in the U.S.
coronary heart disease or coronary artery disease page 82
400
The heart has four valves what are they
Tricuspid valve pulmonary or pulmonic valve mitral valve aortic valve
400
When upper heart chambers contract irregularly
What is atrial fibrillation
400
True/False Heart failure is a serious condition, and usually there's no cure. But many people with heart failure lead a full, enjoyable life when the condition is managed with heart failure medications and healthy lifestyle changes.
What is Both true.
500
primarily a condition of the elderly and as such it is a major and growing public health problem in the United States.
What is Heart failure page 81
500
HF may occur as a result of
Page 81 1) impaired myocardial contractility (systolic dysfunction, commonly characterized as reduced left ventricular ejection fraction). 2) increased ventricular stiffness or impaired myocardial relaxation (diastolic dysfunction) 3) A variety of other cardiac abnormalities 4) states in which the heart is unable to compensate for increased peripheral blood flow or metabolic requirements.
500
What are the degrees of a heart block? Explain
First degree- conduction time is prolonged, but all impulses are conducted. Second degree- occurs in two forms- Mobitz type 1(Wehnckebach) and type II. Type I heart block is characterized by by progressive lengthening of conduction time until a impulse is not conducted. Type II heart block denotes occasional or repetitive sudden block of conduction of an impulse without previous lengthening of conduction time. Third degree a block is present, no impulses conducted
500
Any tachycardia arising above the AV junction for which the ECG shows a P wave configuration different form that for sinus rhythm. Characterized by an atrial rate between 150-200 beats per minute and may result from enhanced normal automaticity, abnormal automaticity, triggered activity , or reentry. What am I??
What is Atrial Tachycardia
500
HF may occur as a result of
What myocardial contractility (systolic dysfunction, commonly characterized as reduced left ventricular ejection fraction) Increased ventricular stiffness or impaired myocardial relaxation. A variety of other cardiac abnormalities, including obstructive or regurgitent valvular disease, intracardiac shunting, or disorders of heart rate or rhythm. States in which the heart is unable to compensated for increased peripheral blood flow or metabolic requirements.
