Arrhythmia Anomalies

Arrhythmia anomalies can occur for a variety of reasons. Often they are traced to problems with patient

electrodes, lead wires, or cables. Always ensure patient ECG signal is as clean as possible.

Problem May Be Caused By Try This...

Anomalous event

classifications.

Noisy ECG signal causing

false event detection and

classification due to

attachment, motion, or

electrical artifact.

Ensure ECG signal is clean

by using good setup and

lead placement techniques.

If ECG is still noisy, check

electrodes, lead wires, and

patient cable for possible

failure.

Minimize any possible

muscle motion, contact, or

electrical artifact.

Lead change or change in

patient’s rhythm has altered

learned dominant beat.

Relearn current dominant

rhythm at central station.

T-waves and/or P-waves

are being detected and

classified.

Select a lead that

maxi mizes R-wave and

results in P-waves and T-

waves no larger than 3 mm

on recorder. Relearn ECG

after making adjustments

via central station.

Atrial fibrillation or flutter

are difficult rhythms. The

frequent rate changes and

distortion of QRS may

result in miscalculation of

beats and events.

Adjust limits to minimize

false Run, Missed Beat, and

SVTach classifications.
