Sweep speed accuracy: 2%. ECG rhythm: 7.5 s/lead. Leads: user-selectable. Recall reports: 10 s of 6 user-selectable leads. Displayed data: heart rate, target heart rate, blood pressure, total exercise time clock, stage clock, 4 current median complexes, treadmill speed and grade, ventricular ectopic/minute counter, 3 channels of rhythm, protocol and stage of exercise, warning messages and prompts.
System
Digital sampling rate: 250 Hz. A/D conversion: 12 bits. Chassis leakage current: <100 mA (meets AAMI standards SCL 1278). Patient leakage current: <10 mA. Common mode rejection: 130 dB, minimum, up to 180 dB with digital processing. AC elimination: 50/60 Hz digital filters. Electrode offset tolerance: 320 mVDC. Internal maintenance test: automatic self-tests. Diskette drive: 8.89 cm (3.5 in), 2 MB, double sided, quad-density, and MS-DOS format compatible.
Processing
ST level and slope determination: up to 15 leads. Medians: incremental updating with elimination of artifact and aberrance in all leads. ST level measurement: manually selectable post J point. Heart rate: 16-beat sliding average updated every beat; minimum 35 beats/min, maximum 300 beats/min. QRS detection: band-pass filtered composite of three user-selectable leads. Arrhythmia: automatic detection and documentation.
Input
Channels: simultaneous acquisition of up to 15 channels. Impendence: 100 M1/2, defibrillator-protected. Dynamic range: 320 mVDC. Electrode offset tolerance: 320 mVDC.
Output
Standard outputs: one analog output, one waveform output, one TTL output with variable pulse width, polarity and delay, QRS beep.
Writer
Method: thermal dot array (horizontal 1000 dots/in at 25 mm/s, vertical 200 dots/in). Channels: 6, user selectable. Frequency response: 0.01 to 100 Hz, 0.01 to 40 Hz, 0.01 to 20 Hz, user-selectable. Sensitivity: 5, 10, and 20 mm/mV. Paper speed: 5, 12.5, 25, and 50 mm/s, user-selectable. Paper style: thermal, perforated, 21.59 cm x 27.94 cm x (8.5 x 11), Z fold, 300 sheets/pack
Acquisition Module
Analog Sampling rate: 2000 Hz. Microprocessor-controlled: 10 IEC and AHA color-coded lead wires standard, 14 lead wires optional; (additional lead wires user-definable)
Keypads
Control panel: contains manual treadmill, test/procedures, and report controls. Alphanumeric keyboard: with TRIM KNOB for blood pressure, patient demographics, and impressions entry.
Reports
Classical 12-lead: note: reports can be transferred to the NUSE network by diskette. Incrementally averaged medians: with real-time rhythm and ST level; user-selectable in two formats. 3- or 6-channel rhythm strips: available for real-time, recall or arrhythmia documentation (leads user-selectable). Tabular presentation of final report data including: phase, stage, speed, grade, heart rate, blood pressure, rate-pressure product, ectopic, maximum ST depression, and physicians impressions. Sample cardiac cycles: presented at user-defined intervals. Trend graph: heart rate, ST levels, ST slopes, blood pressure, PVCs/m.
