Immediate Effects of Upper Thoracic Spine Manipulation on Hypertensive Individuals. - Spinal manipulation impact on hypertensive patients

Results: Within-group changes in PR interval and QRS duration demonstrated that the atria were transiently less active post-spine manipulation and the ventricles were more active post-spine manipulation, however the changes were clinically minimal. Conclusion: The results of this study, and the limited existing normotensive thoracic-specific spine manipulation research in this field, suggest cardiovascular physiology, short-term, is not affected by upper thoracic spine spine manipulation in hypertensive individuals to a clinically relevant level.
