7. ECG

What is the abbreviation for electroencephalogram?

EEG ( a test that measures and records electrical activity in the brain utilizing electrodes)

Which of the following diagnostic procedures uses ultrasound to display an image of structure of the heart?

echocardiogram

After validating ECG order, collecting all supplies, and ensuring the machine is in proper working order, the professional performing the ECG's next action should be to

Identify the pt

What are correct actions for professional performing to take during excessive stress testing, except which?

Leave the pt alone to help them not feel pressured

When performing an ECG on a pt who is obese and wandering baseline is present, which of the actions should the professional performing the ECG take? Select 2

Ensure that new electrodes and clean clips are used,. Ensure good skin preparation

A Pt with Parkinson's come in for an ECG with noticeably severe tremors. What should the MA do to ensure a proper reading?

Have the pt slide their hands under their buttocks

Where should the V4 electrode be placed on the body?

left midclavicular line, 5th intercostal space

Which of the following are appropriate acts for the medical professional performing ECG to take when placing electrodes on Pt's skin for a 24 hr holster monitor?

Avoid scars and incisions,. Tape lead wires to pts skin,. Abra de the skin with an alcohol pad or dry 4x4

What is the approximate amount of time for the QRS complex to record on an ECG?

0.06-0.10 seconds

After performing an ECG, the MA assistant notices wandering baselines in the precordial lead. What is the most appropriate next step?

Re-evaluate chest leads.

What occurs when a singular irritable impulse fires so rapidly it bombards the AV node, causing V shaped or upside down V shaped waves?

atrial flutter

While performing an ECG on a pt, electrodes keep falling off which of the following should the MA do?

Place tape over wires of the electrodes,. Clean the skin with 70% isopropyl

To prevent wandering baseline artifact, the medical assistant should ensure the patient is

cleansed with alcohol prep pads.

A series of small uniform spikes on the ECG paper most likely represents:

AC interference ( can disrupt ECG rhythm)

During an ECG, the right leg provides grounding for which leads?

augmented ( right leg grounds the augmented leads in the course of an ECG procedure.)

To correct a wandering baseline, the medical assistant should

replace loose electrodes

Which of the following indicares a normal sinus rhythm?

PR interval of 0.14 second, QRS complex of 0.10 seconds, QT interval of 0.40 seconds and HR of 78

The P wave of an ECG indicates

atrial contraction

Which of the rhythms identifies on an ECG prompts the MA to notify the provider immediately?

Ventricular fibrillation

Which of the following ECG leads records the electrical activity of the inferior surface of the left ventricle and is closest to the heart?

Lead (II)
