Utah_2018_08_09_TorsoTank

This data comes from a Langendorf perfused canine heart, supported by a second canine. Data was recorded from a pericardiac cage electrode array (256 electrodes) and a torso tank (192 electrodes). The torso was filled with conductive fluid approximating human torso conductivity. Included are recordings from three different activation sequences, outlined in citation 2, Bergquist et. al 2021. The first is an anterior ventricular paced beat (avp), the second is a posterior ventricular paced beat (pvp), and the third is a sinus beat. All three activation sequences were recorded from both the torso tank and cage electrode simultaneously.


Species: Canine

Keywords: homogeneous torso tank, double-dog, canine, pacing, pericardiac cage, sinus

Software: SCIRun, map3d

The torso measurement electrodes are a subset of the full closed geometry. Included are recording sfrom three different activation sequnces, outline in citation 1, Bergquist et. al 2021. The first is an anterior ventricular paced beat (avp), the second is a posterior ventricular paced beat (pvp), and the third is a sinus beat. All three activation sequences were recorded from both the torso tank and cage electrode simultaneously. They are stored in matlab structures according to the EDGAR data standard. Each time signal structure (ts) contains the ts.potvals field, a matrix of n by t potentials recorded from n electrodes at t time instances. The sampling rate was 1000 hz. Each ts structure also contains a .fids field which has hand marked fiducial points fo rht QRS start (2), QRS end(4), t-wave start(5), t-wave end(7), t-wave peak(6), activation time per electrode(10), and recovery time per electrod(13). These fiducials were identified using PFEIFER (citation 2).&nbsp;</p>
