TROUBLESHOOTING

AC Interference

Appears on the ECG as even-peaked, regular voltages
superimposed throughout the tracing. It may appear in conjunction
with muscle tremor.

Causes:
• Dirty or corroded lead wire tips or electrodes
• Loose electrode connection
• Patient or technician touching an electrode during recording
• Patient touching any metal part of a bed or examination table
• Broken lead wire, patient cable or power cord
• Electrical devices in the immediate area, lighting, concealed

wiring in walls or floors

• Improperly grounded electrical outlet

Muscle Tremor

Appears on the ECG as random, irregular voltages superimposed

Interference (EMG)

on the tracing. It may resemble or occur in conjunction with AC
interference.

Causes:
• Patient is uncomfortable, tense, nervous or apprehensive
• Patient is cold and shivering
• Patient has neuro or muscular disorder
• Examination table is too narrow or short to support limbs

comfortably

• Patient may have “white coat” effect

See “Getting a Quality ECG” for suggestions
