|
Describe how ECG paper works |
Marks the paper with the stylus and uses heat. |
|
|
What is standardization of the ECG |
Quality control measures an accurate and reliable recording. The mark is 2 large boxes and 10 small boxes. |
|
|
Describe bipolar leads |
Measures flow of electrical current in 2 directions at the same time 1,2,3 produce deflections. |
|
|
Describe augmented leads |
The tracing are most commonly arranged in a grind of 4 columns and 3 rows. |
|
|
Describe chest leads |
V1-V6 records hearts voltage from front to back. The electrical current traveling through the heart is recorded from inside the heart to a point on the chest wall where electrodes are placed |
|
|
Name 3 ECG capabilities |
3-channel recording, interpretative ECG, EMR connectivity, teletransmission |
|
|
What are some reasons that an ECG might show artifacts |
Electrical activity picked up by machine include: Electrical activity outside, loose electrodes, unattached leads, muscle movement. |
|
|
What should you do if there is artifact? |
Make sure all electrical devices are away from, machine, check leads, wires, wires follow body contour, cover patient with blanket and move machine away from wall. |
|
|
What is muscle artifact |
Caused by voluntary or involuntary movement |
|
|
What is an alternating current artifact caused by |
Outside electrical activity - check outlet, switch outlets, move away from wall, no dangaling cords, turn off lights |
|
|
Describe a holter moiniter |
Portable ambulatory moniter system for continuous recording of electrical activity. Has 5 leads. Used to diagnosis cardiac rhythm, rate and conduction abnormalities. |
|
|
Premature atrial contraction |
Beat that comes before next normal beat due. Found in healthy people associated with intake of stimulus |
|
|
Paroxysmal atrial tachycardia |
Abrupt episode of tachycardia with constant rate that is usually between 150-250bpm short burst last a few seconds found in young healthy people with no underlying heart disease |
|
|
Paroxysmal atrial tachycardia |
Abrupt episode of tachycardia with constant rate that is usually between 150-250bpm short burst last a few seconds found in young healthy people with no underlying heart disease |
|
|
Atrail flutter |
Rapid regular fluttering of atrium in which heart rate falls between 250-350bpm healthly people and is found in people with heart disease |
|
|
Atrial fibrillation |
P waves have no definite pattern or shape P waves appear wavy between QRS complex. Healthy people and people with heart disease |
|
|
Premature ventricular contraction |
Most common rhythm disturbance on ECG beat comes early in cycle is not proceeded by P wave and distorted QRS complex and T wave in opposite direction to R wave of QRS complex |
|
|
What is angina period and what is caused by? |
Set of symptoms rather than a disease pain in chest occurs when muscle tissue of heart does not revive enough oxygen resulting in discomfort or pain under sternum |
|
|
Placement of aVR |
Records electrical current traveling between right arm and central point |
|
|
AVL |
Records current traveling between left arm and central point of right arm |
|
|
AVF |
Left leg and central point between right and left arms |
|
|
V1 |
4th intercostal space at right margin of sternum |
|
|
V2 |
Same as v1 except left sternum |
|
|
V3 |
Midway between posistions 2 and 4 |
|
|
V4 |
5th intercostal space at junction of left midclavicular |
|
|
V5 |
At horizontal level of position 4 and at left anterior axillary line |
|
|
V6 |
At horizontal level of position 4 at left midaxillary line |
|
|
What can you try to do if a lead will not stay and keeps popping off? |
Tape it down or get new electrode |
|
|
How should you describe an EKG to a patient |
Machine that records electrical activity of heart will not shock you only records electrical current of heart |
|
|
Cardiac cycle |
1 complete heart beat |
|
|
How many leads on EKG |
12 |
|
|
Glavanometer |
Takes voltage revived from heart and turns it into mechanical motion |
|
|
Normal sinus rhythm |
All waves and intervals are in normal ranges |
|
|
Bigeminy |
Is Dysrhythmia which every other heart beat is ventricular contraction |
|
|
Which leads are recorded simultaneously on 3 channel lead |
V4, V5, V6 |
|
|
Bipolar leads |
Reads limbs |
