Overview Description

​The American Heart Association (AHA) developed a database of arrhythmias and normal electrocardiograms (ECG) contained in two series of meticulously-edited, beat-by-beat, annotated recordings. The AHA ECG database is available on one convenient DVD reformatted for use with windows-based operating systems. You can develop your arrhythmia detection routines using series one recordings and check your final routines using series two recordings.

Perfect Training Tool

Health professionals benefit from training with the annotated recordings because of the careful identification of specific arrhythmias. This is an asset for medical schools, hospital in-service training, and technical training programs. Use the viewer (included with the database on the DVD) to view ECGs with or without the beat-by-beat annotation visible.

Eight Arrhythmia Categories

The DVD contains a total of 154 recordings including the following arrhythmia categories:

  • No PVCs
  • Isolated Uniform PVCs
  • Isolated Multiform PVCs
  • Bigeminy
  • R-on-T Beats
  • Couplets
  • Ventricular Rhythms
  • Ventricular Fibrillation or Ventricular Flutter Beats

Each recording is three hours long and the beats in the last 30 minutes have been classified. The digitized information includes: 2-channel ECG data at 250 samples/second, 12-bit precision; beat arrhythmia classification data; and timing data. A sample recording is available under the resources tab.

How Recordings Were Developed

Development of the arrhythmia database started in 1977 as a project of the American Heart Association, Council on Clinical Cardiology, Committee on Electrocardiography and Clinical Electrophysiology. The National Heart, Lung and Blood Institute provided funding. The recordings were developed from recordings of actual patients and donated to the project by a number of institutions. Thousands of subjects were considered during the process of selection and editing.
