308 ENG - Version 2.1 – P/N 04130.2
The following are defined as shockable rhythms:
• ventricular fibrillation
• ventricular tachycardia, rate > 180/min
ECG database for validation of the analysis software
The ECG data used originate from recordings from the AHA Database CD ROM
Series 1.
Application on validation of the analysis software
A total of 1392 measurements from ECG sections which constitute a
representative cross-section of all ECGs have been included for validation of
the analysis software.
According to AHA recommendation, the data records are divided into three
classes. A further class of different rhythms was not included in the
measurements owing to irregularities.
