Web心臓再同期療法（cardiac resynchronization therapy：CRT）は，重症心不全患者 において同期不全を有する低左心機能患者に対する治療オプションの一つである． WebAdaptivCRT™ is a dynamic, physiologic pacing algorithm that enhances cardiac resynchronization therapy (CRT) by adjusting CRT parameters automatically with changes in patient activity levels and conduction status. It leverages a patient’s intrinsic RV conduction when possible while still maintaining CRT.
WebAug 12, 2016 · VV Interval. Classically, CRT is accomplished by pacing the left ventricle simultaneously with right ventricular activation (or pacing). It may, however, be the case that different timing sequences between the two ventricles (the VV interval) would improve the efficacy of CRT in some patients. Data exist, for instance, suggesting that in some ... WebCorpus ID: 224385591; 心エコーの左室流出路-速度時間積分(LVOT-VTI)により最適化されるCRTのVVディレイ @inproceedings{Haruna2014LVOTVTICRTVV, title={心エコーの …
