EKG Made Simple Chapter 5 Technical Aspects of the EKG

Somatic Tremor Artifact is commonly caused by

• Patient movement

• Respirations

• Lotion on the skin

• Electrical Interference

Sixty-cycle interference is commonly caused by

• Patient movement

• Respirations

• Lotion on the skin

• Electrical Interference

The most common cause for the P wave, QRS complex and T wave to be inverted in Lead I is

• Dextrocardia

• Incorrect lead placement

• myocardial infarction

• Left bundle branch block

The "gain" setting on the EKG machine is concerned with

• The amplitude of the waves and complexes

• the size of the patient

• Einthoven's law

• Electrical conduction through bundle branches

Normal paper speed for printing out the EKG is

• 25 mm/sec

• 50 mm/sec

• 10 mm/sec

• 20 mm/sec

Macroshock and microshock are LEAST likely to be caused by which of the following?

• Frayed electrical cord on the EKG machine

• Broken grounding prong on the electrical cord

• Properly maintained EKG machine

• Ungrounded hospital bed on which the patient is lying

Which of the following is NOT a method for determining artifact versus a real rhythm?

• Check your patient for signs of decreased cardiac output

• Check the wires & patches

• Follow any visible QRS complexes

• Immediately defibrillate the patient

Your patient is having chills. WHat kind of artifact can this produce?

• 60-cycle interference

• Baseline sway

• Broken recording

• Somatic tremors

Your patient is smiling and visiting with family, but the cardiac monitor shows that the patient's heart has completely stopped. The rhythm on the monitor is thus

• Artifact

• A life-threatening emergency

• Dangerous but it can wait awhile

• Toothbrush Tachycardia

The artifact caused by jiggling of wires during tooth brushing is called

• CPR artifact

• Toothbrush Asytole

• Toothbrush Tachycardia

• PVC's
