ST1501 Features

The ST1501 STEMI ECG Simulator 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 to V4R. The ST1501 includes an ECG snap, V4R, to simulate a direct view of the right ventricle.

ST elevation in **V4R** confirms **right ventricular STEMI**.

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.

ST elevations in V8 and V9 confirm **posterior STEMI**.

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.

**Hyperacute (T↑)**
T waves are broad, peaked (seconds after occlusion)

**Acute (ST↑)**
ST waves are elevated (minutes to hours after occlusion)

**Post-acute (Q↓)**
Q waves deepen (less than 24 hours after occlusion)

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.

**Left Bundle Branch Block**
ST elevation and positive T waves in V1 and V2

**Left Ventricular Hypertrophy**
ST elevation in V1 - V3

**Pericarditis**
Concave ST elevation and PR depression in leads I and II

**Wolff-Parkinson-White**
Prominent R waves and inverted T waves in V1 - V3

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".

Paced Beats

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

Battery

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.

For further information about the functions of the simulator, you can view the operating instructions: ST1501 Operating Instructions [pdf]
