STRIP ANALYSIS AND CLINICAL RESPONSE
BREAKDOWN FULL REVIEW
◉ Atrial flutter characteristic. Answer: The 'saw tooth' or 'picket
fence' appearance of waveforms before the QRS.
◉ Paced atrial rhythm. Answer: Indicated by a regular P wave
followed by a spike before the QRS complex.
◉ 60-cycle ECG interference troubleshooting. Answer: Cleaning the
skin with isopropyl alcohol.
◉ Lead II ECG rhythm strip. Answer: Demonstrating a regular, long
PRI suggests first degree heart block.
◉ Accelerated junctional. Answer: A regular rhythm with a narrow
QRS complex and no noted P waves with a rate greater than 60 bpm.
,◉ Idioventricular escape. Answer: A regular rhythm with a wide QRS
complex and a rate between 20-40 bpm.
◉ Premature ventricular contraction. Answer: An early heartbeat
originating from the ventricles.
◉ Malfunctioning pacemaker. Answer: A pacemaker that does not
deliver the necessary electrical impulses.
◉ Loss of capture. Answer: When a pacemaker's electrical impulse
fails to stimulate the heart.
◉ Oversensing. Answer: When a pacemaker incorrectly senses
electrical activity and does not deliver an impulse.
◉ Atrial depolarization. Answer: Represented by the P wave on an
ECG.
◉ Ventricular repolarization. Answer: Represented by the T wave on
an ECG.
◉ Irregular heart rhythms. Answer: Can be caused by increased
vagal tone.
,◉ Complete heart block. Answer:
◉ Second degree AV block, Mobitz type I. Answer:
◉ Second degree AV block, Mobitz type II. Answer:
◉ What should you do if all required information is not on the
form?. Answer: Ask the patient or obtain the information from the
medical record.
◉ Which of the following is NOT a consideration for handling and
storing printed ECGs?. Answer: They require no special handling and
can be stored for up to 50 years.
◉ What is the most appropriate response if a patient with a trans
telephonic monitor shows symptoms of slurred speech and tingling
in the left arm?. Answer: Activate EMS.
◉ Which heart chamber primarily receives deoxygenated blood
from the body?. Answer: Right atrium.
◉ If the dysrhythmia originates from above the ventricles and you
notice a wide QRS complex, which rhythm could this be?. Answer:
Bundle branch block.
, ◉ What is vital for ensuring continuity of care in a medical
environment?. Answer: Ensuring clear and complete documentation.
◉ Which of the following should be included in patient education for
self-monitoring?. Answer: What to do when the device emits an alert
sound.
◉ What is the purpose of the gain control on the ECG machine?.
Answer: To modify the amplitude of the signals.
◉ How many electrodes are typically used with a Holter monitor?.
Answer: 10
◉ What device allows lay rescuers to assist a person experiencing
sudden cardiac arrest?. Answer: Automatic External Defibrillator
(AED).
◉ Which statement about pulmonary circulation is most accurate?.
Answer: It transports blood to and from the lungs for oxygenation.
◉ What type of electrode is most commonly used for an ECG?.
Answer: Disposable.
