My Husband Had Ablation Surgery For Afib. He Wants To

My husband had ablation surgery for afib. He wants to use an inversion table for his back pain. Is it safe with his history of afib. He does not have high blood pressure or take any high blood pressure meds. He does have a disc herniation in his cervical spine. I read that inversion may actually cause more pressure in the cervical spine and make that worse. Is that true.
