describe the correct electrode placement for Lead V8 left midscapular line
describe the correct electrode placement for Lead V8R right midscapular line
describe the correct electrode placement for Lead V7 left postierior axillary line
describe the correct electrode placement for Lead V7R right postierior axillary line
what sign shoudl the EKG technician be concerned about ina patiend undergoing stress testing decreased heart rate, can be a result of ischemia and should prompt to stop test & notify physician
statement made by EKG technician correctly prepares the patient for telemetry monitoring You may clean the skin with an alcohol pad (or soap & water)
Rhythm that is characterized by upright P waves, narrow QRS complexes and a ventricular rate between 60-100 sinus rhythm
Rhythm that is characterized by absent P waves, wide QRS complexs and a ventricular rate between 20 -40 Idioventricular rhythm
Rhythm that is characterized by absent P waves, narrow QRS complexes and a ventricular rate between 40-60 Juctional rhythm
For 5-lead placement for ambulatory monitoring, where should the EKG technician place the green ground electrode On a rib on the lower right side
5 lead what is placed on the right area of the manubruium negative electrode
5 lead what is placed fifth intercostal space midclavicular and also place on the xipoid process of the stemum positive electrodes
what lead is created between the left arm and left leg lead III
what lead is created between the left arm and the right arm plus the left leg aVL
what lead is created betweent he left leg and the right arm plus the the left arm aVF
what lead is created between the right arm and the left arm Lead I
what would cause an IKG tech to stop a stress tess dizziness indicates a decrease in cardiac output
5 lead where is the red lead placed lower left torso
EKG see a somotic interference somontic is a tremor or seizing
EKG woman is sweating profusely may cause what wandering baseline
EKG woman talking on cell phone may cause what a thick pattern on the EKG printout due to AC interference
Myocardial infarction can often be dectected by the presence of Pathologic Q waves
M shaped P waves indicate what left atrial enlargement
An EKG technician is measuring the intervals on an EKG tracing -what is anticipated finding of impaired conduction trhough the AV node Prolonged PR interval- is a direct reflection of AV node conduction
What EKG change is associated with myocardial injury ST segmant elevation
What EKG change is associated with hypokalemia T wave flattening
What EKG change is assoicated with ST segmant depression mycardial ischemia
what EKG change is assoicated with T wave inversion mycardial ischemia
an EKG has a 2mm STelevation in leads I, AVL V5, V6, what type of infarction would this represent Lateral infarction (it's observed in the septum- observes the inferior heart)
what leads changes are best indicators of a posterior infarction V1 and V2
ekg tech notices that none of the leads are giving a reading- which limb should the tech check first right leg- it is shared by all leads
right arm affects what leads lead I and II and the augmented limb leads
left arm affects what leads lead I and III and the augmented limb leads
left leg affects what leads leads II and III adn the augmented limb leads
for a normal patient what describes the pattern of the anticipated QRS complex in V4 half positive, half negative
what is characterized by ST segment depression and T wave inversion Myocaridal ischemia
a patient has difficulty understanding why she needs an ambulatory monitor after having an ekg two days prior, how do you explain your doctor wants to study your heart over a longer period of time
where should an ekg place electrodes for leads V7, V8 V9 evenly spaced on the back between the axillary line and the vertebral column at the 5th intercostal space
an ekg tech notices that hte waveforms on an ekg are very close together and the patient has an unusually rapid heart rate- in order to spread out hte tracing, the tech should change the paper speed to what? 50mm/second- a faster paper speed spreads out he waveforms and makes the tracing more easily readable
what are signs of myocaridal ischemia while performing a treadmill stress test on a patient peaked, hyperacute, and broad-based T waves and convex ST segments are classic findings
an ekg tech is asked to obtain right-sided ikg on patient with suspected acute myocardial infarction of the interior wall- what leads is most sensitive and specific to right ventricular ischemia Lead V4R
the QRS is too tall to fit on the EKG pater what action should the tech take change the gain control to 1/2- due to this will shorten the wave by q/w ton the vertical axis making it so it can be visible on the graph paper
on a 12 lead on an infant patient what modifications can be made putting limb lead to the torso
in order for an ekg tech to control and regulate the output or height of ekg waveforms should use what control sensitivity (speed would control the width not height)
what electorde is used to create leads I, II and aVR right arm- it is the only lead that shows thes specific areas of the heart
what ekg finding differenctiats acceslarated idoventricular rhythm from junctional rhythm accelerated idoventricular rhythm has a wide QRS complex
performing a stress test patient complains of heaviness on his chest and becomes diaphoretic, thes are signs and symptoms of what myocardial infartion
perfomring a stress test and has faintness, blackouts and temporary hemiparesis, not chest heaviness or diaphoresis- sign of what transient ischemic attack
what is cerebrovascular accident lack of oxygen to the brain due to lack of blood flow
what are signs & symptons of cogengestive heart failure include fluid overload due to lack of good blood flow
what artery is the prefereed site for measuring an adult after a stress test radia is the easiest to access and most palpable for an adult
what artery is preferred for an infant brachial
what abnormality is associated with large U waves on the EKG decreased potassium level causes U waves to become visible
what artifact looks like on ekg small bumps regular consistant with same amplitude electrical interference
what wave has absent p waves , irregularly irregularrhythm and ventricular rate of 60-100 atrial fibrillation
what wave has varible p waves and a ventricular rate greater than 100 min multifocal atrial tachycardia
what rhythm character has the presence of large pacer spikers followed by wide QRS ventricular pacemaker
