Operators Manual

2-18

The MPS450 simulates either bigeminy or trigeminy incorporated within a normal sinus

rhythm (80 BPM), using type-1 (left-focus) PVCs.

Action in the Menu-Control Mode

1. Press the top-menu key labeled ARRHY.

2. Select VENT.

3. Scroll to the LCD screen for the desired simulation: BIGEMINY or TRIGEMINY.

4. Select RUN. The bigeminy or trigeminy waveform runs continuously (repeats) until

another arrhythmia selection is made.

Alternatively, in the Numeric-Control Mode, press the number keys for the desired

simulation according to Table 2-12, and select RUN:

Multiple PVCS: Paired PVCS; Run 5 PVCS; Run 11 PVCS

Three series of multiple PVCs run as one-time (nonrepeating) events.

The term multiple PVCs refers to any condition where two or more PVCs occur in a row.

Standard PVCs of this type include a pair of PVCs (also known as a couplet), a run of

five PVCs in a row, and a run of eleven PVCs in a row.

The MPS450 simulates multiple-PVC waveforms with three sequences occurring as one-

time events:

a paired-PVC condition, with a waveform that includes a normal beat followed by

two type-1 (left-focus) PVCs;

a run-5-PVC condition, with a waveform that includes one normal beat followed by

five type-1 (left-focus) PVCs; or

a run-11-PVC condition, with a waveform that includes one normal beat followed by

ten type-1 (left-focus) PVCs plus one type-2 (right-focus) PVC.

Action in the Menu-Control Mode

1. Press the top-menu key labeled ARRHY.

2. Select VENT.

3. Scroll to the LCD screen for the desired PVC simulation: PAIR PVCs; RUN 5 PVCs;

or RUN 11 PVCs.

4. Select RUN. On the LCD screen, RUN flashes to indicate that the selected sequence

of PVCs is running as a one-time event. When the simulation completes, the

command INSRT displays on the screen.

5. To repeat the sequence, select INSRT.

Alternatively, in the Numeric-Control Mode, press the number keys for the desired

simulation according to Table 2-13, and select RUN. (To repeat a PVC series, select

RUN again.)
