In 2014 I had arrhythmia from low potassium (2.4). The ER was able to convert it and have not had another episode since that time. The ER recommended I start seeing a cardiologist. At the time I was on 10 mg of enalapril twice a day. My pulse was high (90) and the doc recommended starting a low dose of Metoprolol (12-1/2 mg twice a day). This brought my pulse down to mid 60's. I was also prescribed (in the ER) 10 meq of potassium twice a day I assume for the rest of my life. In addition, I was having issues with PVC's. My cardio recommended 250 mg of magnesium which solved the problem immediately. Anything more than that dose gave me bowel problems.
My blood pressure over the years rose a bit and I am currently on 20 mg of Enalapril in the AM and 10 mg in the PM. All other dosages of meds remained the same. I have been doing well.
Five weeks ago I decided to cut way back on sugar. This means no more cookies, candies, muffins, etc. I continue to eat foods that contain sugar but not to a great degree. My issues have been snacking. I am in very good health and hike at least a couple of miles a day and I am 5'8" and weigh 145. I am 69 yoa. I am not overweight and I do not have diabetes.
All was fine (except for the cravings). After 3 weeks I noticed that my pulse was lowering to 56 bpm and I started having PVC's again. My blood pressure is under control (120/70) but my pulse was so much lower I was finding myself falling asleep at my desk. This pulse has become my new norm. I didn't like it. I called my cardiologist 3 days ago and he suggested I just take the 12-1/2 mg of metoprolol in the evening and then nothing in the morning. He says I should do that for one week and then stop the metoprolol completely.
The first day of not taking the meds I felt pretty good but pulse was the same. The second day I had loose stool and was fatigued. The third day (today) I am not fatigued and the loose stool stopped this morning. I'm not sure if those symptoms are because of something I ate or as a result of cutting back on the metoprolol. But now on day 3 in the afternoon my pulse is 72 and I feel SO much better. I do still have occasional PVC's.
My question is whether it is possible that the high intake of sweets through the years made my pulse higher and now that I'm going to stick to a sweet free diet I may not have any rapid pulse issues again. The doctor did tell me that I need to stick with this diet in order to quit the bb. Is my dose so small that perhaps I will not have any issues with withdrawal? And could the PVC's be the result of stress over this latest issue with my pulse? And is it possible that once I stop the meds completely I will have a rapid heart rate again and I just have a normal pulse now because I'm on a small dose? Any feedback will be greatly appreciated.
