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.
