6 ECG, Arrhythmia, and ST Monitoring Understanding the Arrhythmia Display

Arrhythmia Status Messages

The monitor displays two types of status messages:

•Rhythm Status Messages -- to indicate the patient’s rhythm.

•Ectopic Status Messages -- to indicate the presence of ectopic beats.

These status messages are shown on the right hand side of the primary ECG wave. They are updated every second, with the exception of the Sinus and Supraventricular (SV) rhythm messages.

The Sinus and SV rhythm messages are updated based on the current heart rate, taking into account the patient category (adult, pediatric, or neonatal). For the message to change from one rhythm status to another, the HR must be in the new range for five beats.

If you have basic arrhythmia capability, you will get only messages for the alarms provided with this level.

Rhythm Status Messages

The label B or E indicates basic (B) or enhanced (E) arrhythmia capability.
