Outline of Final Research Achievements

The effects of precordial percussion pacing (PPP) were assessed in cardiac standstill microminipig model, and the results were compared with those obtained by cardiopulmonary resuscitation by standard chest compressions (S-CPR) and ventricular electrical pacing. Systemic pressure during S-CPR, PPP and ventricular electrical pacing were statistically similar. Activation of the non-selective stretch-activated channels may mediate some of the mechanophysiological effects of PPP. Next, the effects of PPP were assessed in bepridil-induced sinus bradycardia and long QT syndrome models. PPP triggered the ventricular electrical activity resulting in the development of aortic pressures. Meanwhile, PPP did not cause any lethal arrhythmias like commotio cordis in spite of the presence of excessive QT-interval prolongation. To better apply these findings to clinical emergency care, further study of PPP to elucidate more detailed mechanism and effective conditions may be warranted.

Academic Significance and Societal Importance of the Research Achievements

症候性徐脈性不整脈に対する機械的ペーシングはしばしば救急医療の現場においてすぐに治療することが困難な場合があり、簡便ですぐに開始できる心肺蘇生法の開発が求められている。一方で、パーカッションペーシングは心臓振盪のような致死性不整脈を引き起こすリスクが懸念されていた。本研究は、マイクロミニピッグ心静止モデルと薬剤誘発性洞徐脈およびQT延長症候群モデルに対するパーカッションペーシングの有効性と安全性を評価した。今回得られた結果は、パーカッションペーシングが症候性徐脈性不整脈に対する機械的ペーシングとの橋渡しとなるための重要な知見となることが期待できる。
