Performance of a good ECG.

1. The ECG waves must be visible and clear.
The ECG waves such as the P ,QRS complex ,T waves must be visible on the ECG paper.
This makes it easier in identifying any pathological waveforms present.


2.Artifact free.
minimal or no artifact must be present.
Types of artifacts -
 -Muscle artifacts obscure the identification of P waves.
-Respiratory artifacts as the patient breths in and out.
-Electrical artifacts from the mains.-Turn on the notch rejection filter at 50/60 Hz
-Baseline wander artifact caused by movement of the leads.
-Movement artifacts.- the patient ought to be still.

3.Patient data must be included. 

In summary.

1.Prepare electrocardiography machine for use	-Check ECG machine  is in good working order connect it to power.
2. Prepare client for ECG procedure	-Reassure the patient the procedure is safe and the reason for it. -Record client information  -Review client medical history
3. Attach ECG electrodes	-Maintain the client's privacy and dignity throughout procedure -Complete preparation of client's skin for electrode placement as required  -Position the client  correctly and comfortably and place electrodes in accordance with client's needs and current standards  -Attach leads correctly and double check lead placement

4. Produce an ECG tracing by printing

-Produce trace  and check for interference, wandering baseline and amplitude Make sure the waves are visible with no artifacts. -Repeat trace if interference , increased amplitude or wandering baseline is identified -Identify and action abnormal ECG patterns which require immediate medical attention  -Forward trace to cardiologist or requesting medical officer for reading -Record test details according to department and organisation procedures

	5. Complete ECG procedure.          -Remove ECG leads and electrodes from client                                                           -Refer the patient appropriately.   -Clean ECG leads and electrodes on completion of procedure in accordance with infection control guidelines OR  -Dispose of disposable ECG electrodes and other materials in accordance with waste management procedures. -Store ECG machine as required making sure there is no entanglement or kinks of the leads.This will increase the longevity of your machine as well as of electrodes.
