Pvc's and low potassium, This health board is so educated in heart health, thankful to the reads. I had left a message about my most recent holter and the increase in pvc's . I have ran low in potassium for years and follow a very heart healthy diet. Sent home with K-Dur which you put the tablet in water, 3 years ago and since told to eat bananas daily, also a potatoe. I have my potassium and magnesium checked yearly. What if the diet is not enough ? other conditions mentioned do you know of what tests are most helpful? 3.7 was my results last year and will re-check this week. No more palps!
