ECG Echelon Exam |Questions &Rationales
What rhythm shows a normal rate, normal QRS and PRI durations, and an absent beat
or beats? - ✔sinus pause
What wave might not be visible if the pt presents w/ sinus tachycardia? - ✔t wave
In sinus arrhythmia, which interval remains regular - ✔PRI
What is the most common type of rhythm in SVT? - ✔paroxysmal SVT
You would not see a normal _______________ interval on an EKG strip with SVT. - ✔PR
When you have a regular atrial and ventricular rhythm and a normal QRS and PRI and the
atrial and ventricular rate is between 100-150 bpm, this rhythm would be ID'd as -
✔sinus tachycardia
What is the appropriate tx for a stable pt with afib and a controlled ventricular response? -
✔admin anticoagulants and antiarrhythmics
, What is the heart's electrical activity dominated by? - ✔the sa node
In sinus bradycardia, the atrial and ventricular rate is - ✔40-60 bpm
A pt is ID'd as having an uncontrolled ventricular rate when aflutter is accompanied by a
ventricular rate ________________ - ✔>100
What rhythm is initiated by the SA node and transmitted through the atria, AV
junction, bundle branches, and purkinje fibers? - ✔Sinus
Sinus tachycardia is defined as sinus rhythm at a rate of - ✔100-150 bpm
When atropine is ineffective for sinus bradycardia, what would be your next intervention? -
✔transcutaneous pacing
What is one of the primary concerns for a pt presenting w/ afib? - ✔Controlling
the ventricular rate
To be ID'd as accelerated junctional rhythm, the ventricular rate must reach
________________ - ✔60-100 bpm
The criteria for ID'ing a rhythm as SVT includes - ✔a very rapid ventricular rate
a QRS complex within normal limits
What is the one EKG characteristic where normal sinus rhythm differs from
sinus arrhythmia? - ✔The distance between the Ps and the Rs
