A study on the Effect of Yogasana practice on systolic time interval shows that there are no significant changes noted in systolic time intervals and therefore suggests that the practice of these Yogasanas (Head Stand and Shoulder Stand) produces changes in cardiac function, which are well within the normal functioning limits of the heart. Though the practice of Head Stand won't make a significant impact on the functions of the heart, the complexity of heart ailments varies from patient to patient. Hence it is advisable to consult your doctor before practice. Again it is contraindicated for Hypertensive patients. This may further complicate cardiac issues.
