Can Phentermine Be Taken If Having Low Blood Pressure And Heart Rate?

Have I very low pressure and heart rate. Failed the table test in less than 2 minutes. Had so many test and no hel, Had a monitor put in above my heart and found nothing. Been in Enmergency room several times and usually have the crash cart by my side. Had heart rte drop as low as 15 beats pressure aveages about 72/58. Weight and bloating have been an issue along with mirgraines my whole life. I am 59 yrs old. Nine kids in my family and I am the only one with low blood pressure. Drops for no reason and I actually walk into the ER and been in IC for as long as a week. Pace maker was once mentioned but said it would not control everything. Salt was told to me to be a BIG part of my meals-Had very bad side effects from the 2 meds they gave me to help. I went to a doctor for weight and he saw the rae-he gave me phentermine 37.5 mg Weight is good and more important heart rate is now between 119/68-90/70- I know it is still low but compared to my norm it is great feeling energy and not being exhausted. I am nervous about using this pill as it does raise my rates. But it is so nice to finally know and feel like others do. I could use any help you can offer me.
