Glad to help, Rivergirl. I'd mention your symptoms to your doctor and ask them if they would order a blood-calcium test. If you have chronic indigestion -- specifically trouble digesting your food, where it feels like your meals just sit in your stomach -- then you may also be low in B6. If not, then something else may be causing a calcium deficiency (assuming that's the cause of your slow pulse rate, which is not necessarily the case).
If indigestion is also bothering you, you can try eating more B6-rich foods (salmon, trout, halibut, brewer's yeast) and cutting way back on sweets and carbs for a few days. You just might find that all of your symptoms (including the slow pulse rate) correct themselves within a day or two. That might sound astoundingly quick, but that's all of how long it took for my related symptoms to reverse. If it doesn't work, then something else is probably the cause of your slow pulse rate. But it seems mighty suspicious that you have the other symptoms, too. A smoking gun.
Best wishes,
