I sometimes have the racing heart early in the AM. After having this condition for several years and doing much investigating I have determined that the vegus nerve that regulates the heart is connected to the colon and that the origin of the problem is in the digestion with the colon being the source of the condition. Candida,parasites,constipation, diarreha ect should be dealt with. Probiotics along with Bentonite and psyllium should be used for a period of at least one year. This condition can not and will not be corrected by medical doctor quacks. Anything that cleans and improves digestion and colon health is the key. Body acidic alkaline balance is also extremely important.When the body retains to much acid the body creates fat to store those acids so that fat needs to go away as thee acids go away. That is the direction I suggest you follow. I am and doing a little better but still have much work to do. Also buy and use a juicer with heavy greens juicing.
