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
