Coronary-physiology

This simple program has two components

  1. A 'pressure' component, which allows semi-automated calculation of the tension time index and diastolic time index. Beats are averaged or 'ensembled' using automatic ECG segmentation (gating).

  1. A 'flow' component, which allows semi-automated calculation and comparison of coronary flow states, namely mean velocity, peak diastolic velocity, and peak systolic velocity. Again, beats are averaged or 'ensembled' using automatic ECG segmentation (gating).

Data for both components should be supplied as separate files for each flow comparison (e.g. rest and exercise, pre- versus post PCI), in the following format:

Data should be supplied as separate rest and exercise files, in the format:

Patient: , Study: , Session: Default, Study date: 7/14/2017, 

Time	Pa	Pd	ECG	IPV	Pv	RWave	Tm

139.890	99.250	91.000	1.958	26.285	0.500		2:19:178

139.895	97.250	90.750	1.960	27.480	0.500		2:19:179

Each component can be run through its respective 'main_*.py' file, where configuration options are listed.
