A volumetric model of rabbit heart and torso including ECG data and ventricular activation sequence

Data generated and analyzed of our work titled "A computational model of rabbit geometry and ECG: Optimizing ventricular activation sequence and APD distribution". Please see the respective publication for more context.

BSPM_filtered.dat

Contains the filtered ECG Data

BSPM_original.bdf

Contains the originally recorded signal.

CT_DataDCM.zip

Contains the recorded CT images of heart and torso in DCM file format

ECG_NodeIndices.txt

Contains the the node IDs of the torso mesh corresponding to the electrode positions of the ECG Vest

Endocardial_Surface_Papillary.stl

Segmented endocardial surface including papillary muscles

Mat_LeadField.dat

Contains the calculated lead field matrix to be used in combination with the provided Mesh_Ven.vtu. Make sure to keep the node order

# Python example of usage
# Define a read_vm_vec function which reads your calculated data beforehand
import numpy as np

t_begin = 0
t_end = 400
LF_mat = np.loadtxt('Mat_LeadField.dat')
times = np.linspace(t_begin, t_end, t_end-t_begin)
result = np.zeros((len(times), 31))
for i,t in enumerate(times):
vm_vec = read_vm_vec(t)
result[i, :] = LF_mat.dot(vm_vec)[0:31]
result = np.insert(result, 0, times, axis=1)
np.savetxt('BSPM.dat', result)

Mesh_PurkinjeTree.vtp

The resulting optimized Purkinje Node tree. We recommend using ParaView for visualization

Mesh_StimPoints.vtp
