Overview
When used in conjunction with a Spacelabs Medical Ultraview Care Network
monitor, the ECG function provides a means for continuous monitoring of
electrocardiographic signals. It can detect abnormal cardiac rhythms, including
life-threatening arrhythmias such as asystole, ventricular fibrillation, and
ventricular tachycardia.
The basic ECG software provides alarms for high and low heart rates, ventricular
fibrillation, and asystole.
The Multiview I option provides enhanced arrhythmia detection and alarm
capability. Multiview 1 detects ventricular tachycardia, couplets, and single
abnormal beats in addition to the detection and alarm capabilities of the basic
ECG software.
The Multiview II option expands arrhythmia detection to include pauses and
tachycardias of a supraventricular origin. This option also offers storage
capabilities so that trends of arrhythmia episodes, as well as dominant,
ventricular-paced and AV-paced rhythms, can be reviewed, edited, and printed.
Refer to Arrhythmia on page 9-3 for detailed information about the Multiview
options.
The diagnostic ECG feature, which meets all of the requirements and standards
for electrocardiographic devices, provides the capability to obtain a diagnostic
12-lead report as a function of the monitoring system. The 12-lead report is a set
of diagnostic-quality electrocardiographic waveforms that accurately represent
both the detailed cardiac cycle and the cardiac rhythm.
