I Have Been Recently Having PAC's At Random, As In

I have been Recently having PAC's at Random, As in the 3rd beat, the 18th beat, the 10th beat the 70th beat etc., I take 2 1/2 Grams of Monocor at bedtime. I recently been under a huge amount of stress over financial problems, and this started about 2 weeks ago. I have been reading a great deal about this problem and it appears that this can be a major cause. I sleep fairly well, and walk for 1 Hour Every day. I am thinking about going on a "stress free" holiday, for a couple of weeks, and increasing my Monocor to 2 1/2 mg morning and night. I will see my Cardiologist but it will be sometime before I can get in. This happened to me once a couple of years ago, and when I did this, the PAC'c Miraculously Stopped! I am 63 Years. Thank You, Bruce
