Catalog excerpts

External Pacemaker Analyzer Technical Data Fluke Biomedical’s premier SigmaPace™ 1000 analyzes both transvenous and transcutaneous external pacemakers and comes loaded with features to save time and money. This powerful handheld tool conducts the full suite of tests specified by major pacemaker manufacturers in less than half the time it would take using originally prescribed testing methods. Output data is displayed on three selectable screens for easy viewing, including an AV delay time readout providing a performance snapshot for both pacer channels. With capability for long-term trend testing, the SigmaPace 1000 can interrogate a pacer for up to 11 days, capturing data pulse by pulse to detect intermittent and hard-to-find problems. For maximum efficiency, the SigmaPace 1000 doubles as a training tool. Interactive ECG simulation lets users test patient monitoring equipment as well as teach nurses how to operate the pacemaker. • Transcutaneous and transvenous external pacemaker tests • Pulse-output tests (rate, current, volts, energy, pulse width, and AV interval) • Amplitude sensitivity and refractory tests • Demand and asynchronous-mode tests • DC load current test • Output-leakage tests • Line-frequency noise-rejection tests • Wide range of test loads, from 50 Ω to 1500 Ω, specified by manufacturer for transcutaneous pacers • Full range of IEC specified test loads for transvenous pacers 200 Ω, 500 Ω, and 1000 Ω • Pacer output displayed on three different screens • AV readout showing both pacer channels on one screen • Long-term trend test to detect intermittent errors and hard-to-find problems • Interactive ECG pacer simulation with 5-lead output for patient monitor evaluation and pacer operation training • 8-line x 21-character display
