| Outline of Final Research Achievements |
[Purpose] measured and derived 18 -lead ECG and intracardiac ECG were used to examine the validity of derived 18-lead ECG in the diagnosis as a premature contraction source of AF, in particular to confirm the relationship between the V1 and the right atrium, V9 and left atrium in AF. [Method] The effects were verified by 1. Extracting f-wave, 2. performing frequency analysis, and 3. calculate the dominant frequency. [Major achievements] It is confirmed that close dominant frequency values could be extracted from both measured and derived surface ECGs in right and posterior leads in ECGs including obvious f waves.
