Operating Manual

The Symbio Zoll 15 Lead ECG Simulator ST1501 is an easy to use training tool for learning to recognize STEMI, imposter and core ACLS waveforms, as well as for practicing defibrillation and external pacing.

Right Ventricular STEMI
Standard chest electrode placements, V1 - V6, do not look directly at the right ventricle. When a right ventricular STEMI is suspected, guidelines recommend relocating the V4 lead toV4R. The ST1501 includes an ECG snap, V4R, to simulate a direct view of the right ventricle.

Posterior STEMI
Standard chest electrode placements, V1 - V6, do not look directly at the posterior ventricle. When a posterior STEMI is suspected, guidelines recommend relocating the V5 and V6 leads to V8 and V9. The ST1501 includes two ECG snaps, V8 and V9, to simulate a direct view of the posterior ventricle.

STEMI Progression
Changes in T waves, ST segments and Q waves occur during the minutes and hours after an occlusion. Understanding the evolution of a STEMI is essential for correct diagnosis and treatment. The ST1501 presents each of its seven STEMIs in three phases of progression.

STEMI Imposters
Changes to T waves and ST segments aren't always an indication of STEMI. The ST1501 presents four common imposters that resemble STEMI's, but aren't.

Defibrillator and Pacer Training
Safely discharge your defibrillator/external pacer directly into the ST1501 for interactive cardiac emergency training.

Defibrillator Discharge
The simulator detects defib discharges of 50J or greater. The DEFIB DSCHG indicator illuminates when defib detection occurs.

Convert
After you activate convert, the waiting rhythm that you pre-select automatically becomes the running rhythm when a defibrillator discharge is detected.

Pacing Capture Current
You can select five pacing capture current levels: 70, 80, 90 and 100 mA, and "ignore".

When a pacer pulse is detected, paced beats are displayed on your ECG monitor and the PACER PULSE indicator blinks off momentarily.

The ST1501 is powered by four AA alkaline batteries. Low battery indicator illuminates when battery needs to be replaced. Battery saver feature powers-off the simulator automatically when not in use. Battery life is approximately 13 hours.
