Telemetry Rhythms Exam | Questions
SOLVED 100%
A normal ST segment is an - ✔✔Isoelectric (flat) line
What would signal an old MI?
This is a permanent change on the EKG.
Elevation of the ST segment is NOT a permanent change on the EKG. - ✔✔Deep Q wave
An elevation or a depression by 1 mm or more above or below the baseline means... - ✔✔Abnormal
ST segment (Could be a STEMI!)
What causes the T wave? - ✔✔Ventricular repolarization
A state during repolarization when the cell cannot depolarize regardless of intensity. This is a
vulnerable period. Relaxation of the ventricles! - ✔✔Refractory period
This represents the time it takes for the ventricles to depolarize and repolarize. - ✔✔QT interval
What is the normal QT interval duration? - ✔✔0.34-0.43 seconds
This represents a delay in ventricular repolarization - ✔✔Prolonged QT interval
,This puts the ventricles at risk for causing a life-threatening dysrhythmia like Torsades (Type of VTach) -
✔✔Prolonged QT interval
What are 9 causes of a prolonged QT interval? - ✔✔Idiopathic, hypokalemia,
hypomagnesemia, hypocalcemia, hypothermia, liquid protein diets, MI, antiarrhythmics, and
psychotropic meds
If someone is in atrial flutter, then the AV node prevents them from going into: - ✔✔V Tach
6 seconds equals how many big boxes on the telemetry strip? - ✔✔30
1 second equals how many big boxes on the telemetry strip? - ✔✔5
An abnormal (wide) QRS complex will be greater than - ✔✔0.12 seconds
A depressed ST or inverted T wave can represent what? - ✔✔Ischemia
An elevated ST can represent what? - ✔✔Injury (MI)
An elevated ST & inverted T wave can represent what? - ✔✔Myocardial necrosis
Name this telemetry rhythm:
A false and abnormal pattern created by sources other than the heart. - ✔✔Artifact
Name this telemetry rhythm:
Regular rhythm
Rate: 60-100 bpm
P waves: Upright, one P wave precedes each QRS
PRI: 0.12 - 0.20 seconds
QRS: 0.06 - 0.12 seconds
, QT: 0.34-0.43 seconds - ✔✔Sinus rhythm
Name this telemetry rhythm:
Regular rhythm
Rate: Less than 60 bpm
P waves: Normal
PR Interval: Normal
QRS: Normal - ✔✔Sinus Bradycardia
Name this telemetry rhythm:
It is the normal response of the heart to relaxation or sleeping. It can be normal, many people have
resting heart rates < 60 bpm.
It does not require treatment unless the patient becomes symptomatic! - ✔✔Sinus Bradycardia
What are 2 main early symptoms of sinus bradycardia? Due to decreased cardiac output. -
✔✔Lightheadedness and dizziness
What are 9 S&S of sinus bradycardia/decreased cardiac output? - ✔✔Hypotension, syncope,
exercise intolerance, weakness, fatigue, cold, clammy skin, anxiety, chest pain, AMS
What are causes of sinus bradycardia? - ✔✔Drugs: BBs, CCBs, digoxin, and morphine
(B,C,D) Increased ICP
Sudden movement from lying to standing (elderly)
Decreased metabolic rate (sleep, hypothermia, uncontrolled hypothyroidism)
Infectious diseases
Hypovolemia
Hypoglycemia
Cardiac tamponade
Hypo/hyperkalemia
