What are the 6 steps of an ECG?

The 6-Step Method How to Interpret Electrocardiogram Results

  • Identify and examine the P wave. A normal P wave is present and upright.
  • Measure the PR interval. The PR interval or PRI should be 0.12 – 0.20 seconds.
  • Measure the QRS complex.
  • Identify the rhythm.
  • Determine the heart rate.
  • Interpret the strip.

How is ECG measured?

The ECG is measured by placing a series of electrodes on the patient’s skin – so it is known as the ‘surface’ ECG. The wave of electrical depolarisation spreads from the atria down though the IVS to the ventricles. So the direction of this depolarisation is usually from the superior to the inferior aspect of the heart.

Where do you place ECG leads?

12 Lead ECG Placement Guide

Electrode Placement Area
V1 Fourth intercostal space to the right of the sternum.
V2 Fourth intercostal space to the left of the sternum.
V3 Directly between leads V2 and V4.
V4 Fifth intercostal space at midclavicular line.

What is ECG principle?

The basic principle of the ECG is that stimulation of a muscle alters the electrical potential of the muscle fibres. Cardiac cells, unlike other cells, have a property known as automaticity, which is the capacity to spontaneously initiate impulses.

Which amplifier is used in ECG?

The standard circuit, if more than 60dB of common−mode rejection is required, is the 3 op−amp instrumentation amplifier shown in Figure 13 and this circuit is used in most ECG machines. R1 .

What are the 12 leads of an ECG?

Each of the 12 EKG leads represent a different direction of cardiac activation in 3-D space. The standard EKG leads are denoted as lead I, II, III, aVF, aVR, aVL, V1, V2, V3, V4, V5, V6. Leads I, II, III, aVR, aVL, aVF are denoted the limb leads while the V1, V2, V3, V4, V5, and V6 are precordial leads.

Where are electrodes placed?

During an electrocardiogram, small pads or patches (electrodes) are attached to the skin on the chest, arms, and legs. The electrodes are also connected to a machine that translates the electrical activity into line tracings on paper.

What is ECG paper called?

The electrocardiogram (EKG) is the representation on paper of the electrical activity of the heart. This paper has certain essential characteristics for the correct reading of the EKG.

What is an EKG a recording of?

The electrocardiogram (abbreviated as ECG or EKG) represents an electrical tracing of the heart and is recorded non-invasively from the surface of the body. The word ECG derives from the German language. In German, it is elektro-kardiographie.

How to record an ECG?

Recording the ECG trace. 1. Turn the ECG machine on and ensure ECG paper has been loaded into the machine. 2. Double-check all the electrodes are attached in the appropriate locations. 3. Politely ask the patient to remain still and not talk during the recording as muscle activity can interfere with the ECG trace. 4.

How to set up an ECG?

Skin should be dry,hairless,and oil-free.

  • For better electrode adhesion and oil-free skin,rub the area with an alcohol prep pad or gauze paid with benzoin tincture.
  • Reduce electrical resistance minus the skin redness with 5 to 10 gentle strokes.
  • Promote an environment that prevents the patient from sweating profusely.

    • How to make an ECG?

    Prepare yourself for the equipment that will be attached to you.

  • Be aware of how it will feel. The great thing about an ECG is that you do not feel anything as the procedure is underway.
  • Remove your jewelry and any other accessories.[6]…
  • Lie still for the duration of the test.[7]…
  • Follow-up with your doctor.
