Easy Arrhythmia - Wins Single User Shipped in 8 days Cat.# EZ-1 $ 99.00 BUY Site Licence Shipped in 8 days Cat.# EZ-1SL $390.00 BUY

Simulation of two-dimensional activation maps in the heart

Heart activation images were generated by computer simulations using an electrophysiological model that incorporates recent data on cardiac tissue properties and arrhythmia mechanisms. The model parameters were adjusted so that the heart's activity is synchronized with the ECG signals. Each simulation lasts between 10 and 25 seconds.

Database of more than 30 arrhythmias and conduction abnormalities. The database includes:

- Sinus arrhythmia
- Sinoatrial block
- Wandering atrial pacemaker
- Sick sinus syndrome
- Premature atrial complexes
- Unifocal atrial tachycardia
- Multifocal atrial tachycardia
- Atrial flutter
- Atrial fibrillation

- 1st-degree AV block
- 2nd-degree AV block (Mobitz I, II, and 2:1)
- 3rd-degree AV block
- Junctional escape complexes
- Nonparoxysmal junctional tachycardia
- AV nodal reentrant tachycardia
- AV reentrant tachycardia
- Wolff-Parkinson-White pattern

- Premature ventricular complexes (PVCs)
- Ventricular bigeminy
- Ventricular trigeminy
- Ventricular couplets
- Fusion beats
- Multiform PVCs
- Right bundle-branch block
- Left bundle-branch block
- Idioventricular rhythm
- Accelerated idioventricular rhythm
- Monomorphic ventricular tachycardia
- Ventricular flutter
- Ventricular fibrillation

Real ECG signals
The software displays excerpts of two-ambulatory EKG recordings extracted from the MIT-BIH Arrhythmia Database and other EKG libraries. The libraries have been used extensively around the globe by researchers and medical device manufactures to test the performance of arrhythmia analysis algorithms.

Interactive and user-friendly graphical interface
The graphical interface simulates a virtual ECG device with additional animation panels:

• Multimedia buttons to control the animation sequence (Play, Stop, Pause, Frame by Frame, and speed control).

• Knobs allowing the user to change the time and amplitude scales of the ECG tracings.

• Beat-to-beat display of heart rate, QRS complex duration, and PR and corrected QT intervals.

• The ECG intervals are presented in the form of bars with different colors to distinguish between normal and abnormal values.

• ECG screen with different graphical flavors: cyan, amber, and green traces on black background, or blue-dark trace on ECG paper.

• Options to display beat annotations and a screen grid.

Documentation
Each arrhythmia case is documented. The document includes different sections such as description of the arrhythmia, ECG characteristics, and electrophysiological mechanisms. Related arrhythmias that are not included in the software are also discussed.  Figures and diagrams are included to illustrate important concepts. A separate chapter introduces basic concepts of cardiac electrophysiology and mechanisms of arrhythmogenesis.

Limitations
1. The heart is a complex three-dimensional structure. Our simulations, which are based on a two-dimensional model of the heart's electrical activity, portray a simplified projection of the three-dimensional activation maps observed in epicardial and endocardial measurements during electrophysiological experiments.
2. The number of ECG leads is limited to two.

Arrhythmia Chaser - Wins Single User Shipped in 8 days Cat.# EZ-2 $110.00 BUY Site Licence Shipped in 8 days Cat.# EZ-2SL $430.00 BUY

Comprehensive database
The software includes 150 quizzes covering a large spectrum of cardiac arrhythmias from simple cases to challenging ones.

Multiple-Choice Questions
Each test presents 100 cases randomly selected from the database so that two tests will never look the same. This makes the questions less predictable and prolongs the software usage life. The quiz is organized into Multiple-Choice Questions with one correct answer. Answers are in the form of a web browser text format and include hyperlinks. The links allow emphasizing a particular finding by highlighting a specific segment of the ECG.

Digital ECG recordings
Among the benefits of digital signals versus images of ECG strips include accurate measurements of ECG parameters and fine-grain zooming capabilities. We think that the ability to modify the amplitude and time scales of the signals can help reveal details that otherwise would have been difficult to find.

Interactive user interface
The software is highly interactive with easy-to-use graphical controls that, among other things, allow the user to navigate the database, select the questions and answers, and modify the amplitude and time scales of the signal.

History and statistics
A test can be saved and completed later. The results of the saved tests are accessible and can be sorted by name, date, or score.

Limitations
The number of ECG leads is limited to two.

EKG Panorama - Wins Single User Shipped in 8 days Cat.# EZ-3 $ 99.00 BUY Site Licence Shipped in 8 days Cat.# EZ-3SL $390.00 BUY

Description
EKG Panorama is a comprehensive and easily navigable reference library of 12-lead EKGs (two cases include one lead only). The EKGs are digital signals, not reproductions of EKG tracings. The cases are organized in a hierarchical structure similar to a familiar folder tree format. Each EKG is accompanied by a picture illustrating the cardiac condition and a synopsis. In some cases, a ladder diagram is included. The ladder diagram is a useful 2D representation that helps explain cardiac arrhythmias.

Vectorcardiography
The X, Y, and Z signals of the Frank-lead system are displayed in the form of vectorcardiograms in four different referential systems: 3D, frontal plane, horizontal plane, and left sagittal plane. A different color is assigned for each of the P wave, QRS complex, and T wave.

Body surface potential mapping
Body surface potential maps are generated using the heart dipole theory and a realistic torso model. The heart position is calculated to minimize the error between the simulated electric potential and the potential recorded by the chest electrodes.

Learning cases
The library consists of 31 real cases divided into five sections: normal variants (7 cases), myocardial infarction (12 cases), bundle-branch block (7 cases), ventricular hypertrophy (3 cases), and Wolff-Parkinson-White pattern (2 cases).

Test cases
Fifty standard 12-lead EKG tracings are included for practice. Navigation through the cases is straightforward and answers are provided.

Help
The help includes sections that introduce the basis of electrocardiography, some important concepts such as the cardiac dipole and the electrical axis of the heart, vectorcardiography, and ECG diagnoses related to the learning cases covered in the software.

Limitation
One torso model that fits all cases is used to simulate the body surface potential mappings. Due to inter-individual variations in the thorax shape and chest electrode positions, the calculated electric potential does not always correspond to the recorded potential. However, the overall picture of the mappings during the time course of the electrocardiogram is preserved.

Counting the Beat DVD-ROM - Wins Single User Shipped in 4 days Cat.# MU-20 $ 54.55 BUY

A 5 step guide to interpretation of ECG for physiotherapists

Counting The Beat was developed to provide a systematic approach to the interpretation of ECG's.

It is divided in to four sections covering basic anatomy, methods of ECG measurement, step by step interpretation of 18 different rhythm strips and real time interactive self assessment.

It is an ideal tool for both Undergraduate and Postgraduate physiotherapy students who work in acute Cardiothoracic Physiotherapy and in an Intensive Care Unit. It can also be used as part of an orientation program for graduate physiotherapists.

Opportunity. Danger. The workup of chest pain presents both. With thrombolytic drugs, the physician can help the MI patient as never before. Yet never has the danger been greater: Lawsuits for improper management of chest pain are the biggest-dollar loss to internists and emergency physicians.

The Chest Pain Simulator addresses both the opportunity and the danger. It simulates the workup of chest pain, including many non-cardiac causes of pain, and gives the user practice in determining the indications and contraindications to thrombolytics.

"This program is an excellent training environment for physicians interested in learning state-of-the-art thrombolytic therapy for acute myocardial infarction." Medical Software Reviews

The Chest Pain Simulator screen is designed for easy history-taking, examination, testing, and intervention. You manage the Chest Pain Simulator patients like real ones: stabilize, take a full history, perform a physical exam, order and interpret tests, and give treatment orders. The computer watches your workup, looking for weaknesses and pointing them out. The program also rates your time- and cost-efficiency.
