The effects of coronary occlusion location on the RR signal.

The effects of coronary occlusion location on the RR signal.

We carry out the study of the energy contribution of the RR signal in the three frequency bands (LF, MF, and HF) during percutaneous transluminal coronary angioplasty. Furthermore, variables based on instantaneous frequency and on group delay computed from RR signal in the three frequency bands are...
