- 論文の詳細を見る
Synthesized 18-lead ECG derived from standard 12-lead ECG can provide virtual waveforms of right-sided chest leads (V3R, V4R, V5R) and back leads (V7, V8, V9). Several studies showed that P-wave dispersion reflecting inhomogeneous and discontinuous atrial conduction was predictive for atrial fibrillation (AF). Differences of P-wave dispersion between standard 12-lead ECG and synthesized 18-lead ECG are unknown. We measured P-wave duration of each 18-lead and calculated P-wave dispersion in paroxysmal AF patients (61±11 yo, 54 males/13 females). P-wave dispersion in synthesized 18-lead ECG was significantly longer than in standard 12-lead ECG (38±21 ms vs. 29±18 ms, p<0.001). Synthesized 18-lead ECG magnifies P-wave dispersion in paroxysmal AF patients and significance of the findings needs to be confirmed in further studies.
