I woke up with what I call a fast beating heart at 93 bps. I had just had a dream before that and also have been on a stomach detox. Does that cause the heart to work harder? My normal resting heart rate is 62 bpm. I am a 30yo male with no health problems other than digestive. When I woke up it felt like my chest on the left side was full of gas and I burped constantly for about an hour. I am taking Zypan, Probiotic 8, and Papaya Enzyme for my digestion. I have not had sugar in 3 days and have changed my diet drastically. Normal blood pressure is 117/65 My LDL is low and my HDL is normal. My Trig. are 101. Just wondering if it is the intense change in diet that is causing this.
