Which term describes the use of electrical shock to restore the hearts normal rhythm?
The use of electrical shock to restore the heart’s normal rhythm; also known as cardioversion.

Which medication is administered to control irregularities of the heartbeat?
antiarrhythmic
Is damage to the heart muscle caused by a thrombus blocking a coronary artery?
If a blood clot blocks the arteries leading to part of the heart muscle, it will cause a heart attack. If it blocks an artery in the brain, it will cause a stroke.
What term describes damage to the heart muscle caused by a thrombus blocking a coronary artery?
A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. “Myo” means muscle, “cardial” refers to the heart, and “infarction” means death of tissue due to lack of blood supply.
What medication strengthens the contraction of the heart muscle slows the heart rate and helps eliminate fluid from body tissues?
Digoxin (Lanoxin). This drug can strengthen your heart muscle contractions. It also tends to slow the heartbeat.
Which condition causes an irregular quivering action of the atria?
Med Term Chapter 5 Review
| A | B |
|---|---|
| atrial fibrillation (AF) (A fib) | atria beat faster than the ventricles where there is an irregular quivering action of the atria |
| Ventricular fibrillation (V fib) | irregular contractions of the ventricles and is fatal unless reversed by electric defibrillation |
Which condition is the rapid irregular and useless contractions quivering of the ventricles that may result in sudden cardiac death?
varicose veins occur when the valves in the veins malfunction and allow blood to pool in these veins, causing them to enlarge. the rapid, irregular, and useless contractions of the ventricles. instead of pumping strong, the heart muscle quivers ineffectively. this condition is the cause of many sudden cardiac deaths.
Which form of a cardiac arrhythmia is fatal unless reversed?
The most common life-threatening arrhythmia is ventricular fibrillation, which is an erratic, disorganized firing of impulses from the ventricles (the heart’s lower chambers). When this occurs, the heart is unable to pump blood and death will occur within minutes, if left untreated.
What prevents new clots from forming?
In a non-emergency situation, anticoagulants (PDF), or “blood thinners,” are used to keep existing clots from getting larger and to prevent new clots from forming.
What happens if a blood clot does not dissolve?
In addition, when a clot in the deep veins is very extensive or does not dissolve, it can result in a chronic or long-lasting condition called post-thrombotic syndrome (PTS), which causes chronic swelling and pain, discoloration of the affected arm or leg, skin ulcers, and other long-term complications.
Can you massage a blood clot away?
If you are currently being treated for DVT, do not massage your legs. Massage could cause the clot to break loose. If you are scheduled for surgery, ask your surgeon what you can do to help prevent blood clots after surgery.
How do you know when a blood clot is gone?
The pain and swelling from a DVT usually start to get better within days of treatment. Symptoms from a pulmonary embolism, like shortness of breath or mild pain or pressure in your chest, can linger 6 weeks or more. You might notice them when you’re active or even when you take a deep breath.
