Ekg - Final Assessment Part 2

Front 1

Ventricular contraction is slower than normal

True

Back 2

With the Holter monitoring technique, use an event marker on a device. T/f

Front 3

Holter monitoring procedure

Back 3

The pt may experience symptoms not related to his physical activity are instructions given to a pt for what

Front 4

Consult the pt condition with a dr

Back 4

While performing the test on the treadmill an ecg tech observed that the pt experienced the symptoms of angina. What should the tech do immediately

Front 5

Sinus dysrhythmia

Back 5

An ecg tech recognizes irregular pp and rr intervals while all other parameters appear to be within normal limits. What is this

Front 6

AV junction

Back 6

What is likely pacing the heart if the pt pulse is regular and 52 BPM

Hint 6

Av node only delays. Intrinsic rate of av juntion is 40-60

Front 7

Increase speed to 50 mm/sec

Back 7

What kind of changes in ecg machine settings need to be done while performing test on a 3 yr old pt

Hint 7

Baby heartbeat is naturally fast. So you need to stretch the paper

Front 8

Increase the speed

Back 8

When performing a 12 lead ekg on a 3 month old oncoloogy pt, what do you need to do to the ekg

Front 9

Ischemia, injury, infarction

Back 9

What is the sequence of events that occur during an evolution of a coronary artery occlusion

Front 10

Loose electrode artifact

Back 10

The bizarre, erroneous marks on the ecg tracing should be recognized as what artifact

Front 11

Significant q wave

Back 11

On an ecg, what indicates myocardial necrosis

Front 12

Myocardium

Back 12

What is responsible for the mechanical action of the heart

Front 13

Changes the amplitude of the qrs complex

Back 13

What will be changed by increasing the gain of the ecg machine

Front 14

Before, every 2.5 minites, after stress test

Back 14

When are vital signs measured during an exercise stress test

Front 15

Confidentiality

Back 15

Speaking about a pt w a dr who works at a different facility but specializes in treating the condition is a violation of what

Front 16

Right arm

Back 16

Leads I II avr uses which limb lead electrode

Front 17

Pulmonary veins

Back 17

These carry oxygenated blood from the lungs to the left atrium

Front 18

41-100bpm

Back 18

An accelerated idioventricular rhythm is recognized when the qrs is wide and the heart rate equals how many bpm

Front 19

Lead I and avr

Back 19

These leads will show changes if an ekg tech reversed the right and left arm

Front 20

Failure to capture

Back 20

An ekg tech sees pacing spikes on a pt ekg but no electrical activity following the spikes. This is likely due to a pacemaker error known as:

Front 21

In an abnormal location

Back 21

An ectopic focus is a group of cells in the heart that initiates an impulse where?

Hint 21

Like an ectopic pregnancy, its in the wrong place

Front 22

Myocardial ischemia

Back 22

ST segment depression is an indication of what

Front 23

In the bundle of His

Back 23

A supraventricular rhythm may appear where in the heart

Hint 23

Av node never produces, only delays. Bundle branches just conducts. Purkinje fibers produce ventricular rhytms

Front 24

Infants

Back 24

What kind of pts typically require apical pulse measurement

Front 25

Demand pacemaker

Back 25

Spikes are produced once in a while in what kind of pacemaker

Front 26

Estimate hr by counting r peaks in 6 sec strip and multiply by 10

Back 26

When analyzing a hr of the pt experiencing arrhythmia this method should be used to calculate an average value.

Hint 26

Average not exact

Front 27

Ventricular arrhythmia

Back 27

The pr segment is absent in what type of rhythm

Front 28

True

Back 28

Do not drink coffee 3 hours before the test is an instruction before stress test procedure. T/f

Front 29

Ventricular tachycardia

Back 29

This is represented by wide, bizarre qrs complexes

Hint 29

Ventricular fibrillation doesnt produce qrs

Front 30

True

Back 30

Toes earlobes and index fingers can be used as probe placement sites. T/f

Hint 30

Cannot use finger of an arm where automatic blood pressure cuff is applied

Front 31

Every 2 minutes

Back 31

According to Bruce protocol, how often should bp be measured

Front 32

True

Back 32

The intrinsic rate of rhythm originating in the ventricles is 20-40 bpm. Tf

Front 33

True

Back 33

Metropolol a beta blocker should not be administered 48 hrs before a stress test. Tf

Front 34

Rr interval

Back 34

When analyzing a strips you should determine rhythm by:

Front 35

Wide qrs, no p wave and an abmormal t wave

Back 35

Impulses that originate in the ventricles have what kind of characteristics
