Multi-center attempt for creating a validated body surface potential map database

In the attempt reported, the users of the 32-lead limited electrode array in three countries (Hungary, USA, Slovakia) made an effort to pool their BSPM data, to achieve statistically acceptable sample sizes in several classes. A common header and data structure was elaborated based on the existing ones. The data involved in the pooled data bank were analysed according to the quality of the recording and for the adequacy of supporting (ECG independent) clinical data. Until now, altogether 2485 BSPMs were considered, 928 was provided by the CVRTI, University of Utah, 708 was collected in three different Slovakian while 849 cases in two Hungarian centers.<>
