This paper describes a video-assisted thoracoscopic (VATS) procedure to correct phrenic nerve stimulation secondary to cardiac resynchronization therapy. Methods and results:
WebApr 5, 2000 · Diaphragm contractility was assessed as transdiaphragmatic pressure (Pdi) measured with balloon catheters positioned in the midesophagus and stomach. Stimulus supramaximality was assessed by examining diaphragm twitch Pdi (TwPdi) across a range of stimulator outputs; 85, 90, 95, and 100% of maximum. WebThe right hemi-diaphragm was immediately removed and immersed in oxygenated (95% O 2:5% CO 2) Krebs-Henseleit solution at 37°C. A 5 mm-width diaphragm strip was suspended vertically in Krebs-Henseleit solution and then adjusted to optimal length of developing maximum twitch tension (L0).
WebTwitch transdiaphragmatic pressure ( P di,tw), measured following magnetic stimulation of the phrenic nerves, is used to assess diaphragm strength, contractility and fatigue. … WebRegarding diaphragm: A. R & L inferior phrenic artery supply the diaphragm from its thoracic surface B. Lower intercostal nerves assists phrenic nerve in motor supply of the diaphragm C. Subcostal vessels pass behind the medial arcuate ligament D. 55% of diaphragmatic muscles are of slow twitch variety E.
WebDiaphragmatic fatigue was assessed using measurement of the twitch mouth pressure response (tw, Pmo) to CMS of the phrenic nerves. In an additional study, tw, Pmo was used concomitantly with twitch transdiaphragmatic pressure (tw, Pdi) to insure the adequacy of tw, Pmo in the detection of diaphragmatic fatigue. Methods Subjects
