EKG Terminology Quiz 6

_____ a sinus rhythm resulting when the SA node does not initiate an impulse, causing pauses in the heart’s electrical activity; similar to sinoatrial block but with a greater time between complexes. Also called sinus pause

• sinus arrest

• atrial fibrillation

• ventricular tachycardia

• premature ventricular contraction

_____ an atrial rhythm featuring obvious premature beats; other aspects of the rhythm are often normal

• premature atrial contraction

• atrial fibrillation

• ventricular tachycardia

• sinus bradycardia

_____ a heart block rhythm in which the PR intervals of conducted beats gets longer and longer until a beat is totally blocked, and then the pattern resumes; also called Wenckebach

• second-degree AV block type I

• first-degree AV block

• third-degree AV block

• second-degree AV block type II

_____ a situation in which a patient shows organized electrical activity but does not have a pulse; considered a lethal rhythm and requires prompt CPR and notification of the doctor

• pulseless electrical activity

• ventricular fibrillation

• asystole

• atrial fibrillation

_____ an artificial pacemaker that stimulates one area of the heart, either the atria or the ventricles

• single-chamber pacemaker

• dual-chamber pacemaker

• biventricular pacemaker

• external pacemaker

_____ an EKG complex that includes the Q, R, and S waves and corresponds to the contraction of the ventricles; appearance in EKG tracing can vary widely

• QRS complex

• P wave

• T wave

• U wave

_____ contractions of the ventricles in an atrial fibrillation rhythm at a rate of 100 BPM or greater

• rapid ventricular response

• slow ventricular response

• normal ventricular response

• irregular ventricular response

_____ fluid buildup in the lungs; can interfere with gas exchange

• pulmonary edema

• asthma

• bronchitis

• pneumonia

_____ the pulse located on the inside of the wrist, where the radial artery runs just beneath the skin

• radial pulse

• ulnar pulse

• brachial pulse

• carotid pulse

_____ a heart block rhythm in which there is usually a fixed number of blocked P waves for every conducted beat; the relationship between P waves and QRS complexes is expressed as a ratio (e.g., 2:1, 3:1)

• First-degree AV block
• Second-degree AV block, type 1 (Wenckebach)
• Second-degree AV block, Mobitz type II

• Bundle branch block
