What is the appropriate treatment for an unstable patient with atrial flutter and an uncontrolled ventricular response; HR >150 beats per minute? - ANSWERDefibrillation Caffeine, alcohol, and fatigue can be likely causes for (Select all that apply.) - ANSWERAtrial flutter Sinus pause Atrial fibrillation Ventricular tachycardia Which of the following conditions/situations may cause bradycardia? - ANSWERHypoxia Which of the following is an accurate statement about sinus bradycardia?...

normal sinus rhythm (NSR) - ANSWER Sinus Bradycardia - ANSWER sinus tachycardia - ANSWER Sinus Arrhythmia - ANSWER Supraventricular Tachycardia (SVT) - ANSWERan abnormal heart rhythm arising from aberrant electrical activity in the heart; originates at or above the AV node atrial flutter - ANSWERbaseline looks like sawtooth Atrial Fibrillation (A-Fib) - ANSWER

First Degree AV Block Characteristics - ANSWER- P wave before every qrs complex - P waves are upright and uniform - LONG PR INTERVAL 2nd Degree AV Block Type 1 (Wenkebach) Characteristics - ANSWER- pr interval increases with each beat until a qrs complex is dropped 2nd Degree AV Block Type 2 (Mobitz II) Characteristics - ANSWER- p wave before each qrs - some p's are not followed by a qrs - pr interval is the same for every conducted (full) beat - usually bradycardic Third Degree A...

normal sinus rhythm (NSR) Criteria: (PR, QRS, QT, Rhythm: reg or irreg) - ANSWER1 P-wave for Every QRS, REGULAR rhythm PR: 0.12-0.20 QRS: 0.06-0.10 BBB = > 0.12 QT: 0.36-0.44 BPM: 60-100 Sinus Bradycardia Criteria: (PR, QRS, QT, Rhythm: reg/irreg) - ANSWERPR: 0.12-0.20 QRS: 0.06-0.10 QT: 0.36-0.44 BPM: < 60 (Reg. rate) Tx: Atropine 0.5mg, Pace, Dopamine 2-10 mcg/kg/min, Epie 2-10 mcg/min Sinus Tachycardia Criteria: (PR, QRS, QT, Rhythm: reg/irreg) - ANSWERPR: 0.12-0.20 QRS: ...

1. To determine whether there is a delay in impulse conduction through the atria, the nurse will measure the duration of the patient's a. P wave. b. Q wave. c. P-R interval. d. QRS complex. - ANSWERA The P wave represents the depolarization of the atria. The P-R interval represents depolarization of the atria, atrioventricular (AV) node, bundle of His, bundle branches, and the Purkinje fibers. The QRS represents ventricular depolarization. The Q wave is the first negative deflection follow...

Cardiac rhythm - ANSWERThe pattern of electrical activity in the heart Sinus rhythm - ANSWERNormal heart rhythm originating from the sinus node Sinus tachycardia - ANSWERRapid heart rhythm originating from the sinus node Sinus bradycardia - ANSWERSlow heart rhythm originating from the sinus node Atrial fibrillation - ANSWERIrregular and often rapid heart rhythm Atrial flutter - ANSWERRapid and regular

Excitability - ANSWERthe ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization - ANSWERoccurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity - ANSWERthe ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex: the wave of depolarizat...

Normal Sinus Rhythm - ANSWERRefers to a rhythm that originates in the SA node @ a rate of 60-100 BPM and follows normal conduction pattern of the cardiac cycle. Sinus Bradycardia - ANSWERThe conduction pathway is the same as that in sinus rhythm but the SA node fires @ a rate of less than 60 BPM. May be normal in athletes. Symptomatic Sinus Bradycadia S/S - ANSWERPale, cool skin, hypotension, weakness, angina, dizziness or syncope, confusion or disorientation, and shortness of breath. S...

SVT - ANSWER PVC - ANSWER V Tach - ANSWER PJCs - ANSWER Junctional Escape Rhythm - ANSWER SVT - ANSWER SVT - ANSWER Second degree heart block type 1 (Wenkebach) - ANSWER Second degree heart block type 1 (Wenkebach) - ANSWER Third degree heart block - ANSWER Sick Sinus Syndrome - ANSWER Torsades - ANSWER Idioventricular Rhythm - ANSWER
