AHA 数据库 包含哪些类型的心律失常记录

Until about 2003, the only available portion of the AHA database consisted of 80 two-channel excerpts of analog ambulatory ECG recordings, digitized at 250 Hz per channel with 12-bit resolution over a 10 mV range. These 80 recordings, designated as the development set or series 1, are divided into eight classes of ten recordings each, according to the highest level of ventricular ectopy present:

1. no ventricular ectopy (records 1001 through 1010)     
2. isolated unifocal PVCs (records 2001 through 2010)
3. isolated multifocal PVCs (records 3001 through 3010)
4. ventricular bi- and trigeminy (records 4001 through 4010)
5. R-on-T PVCs (records 5001 through 5010)
6. ventricular couplets (records 6001 through 6010)
7. vent
