drug that has been conclusively shown to prevent the cardiovascular complications of diabetes. It helps reduce LDL cholesterol
levels, and is not associated with weight gain.
The most common adverse effect of metformin is gastrointestinal upset, including diarrhea, nausea, vomiting and increased flatulence
METFORMIN is more commonly associated with gastrointestinal side effects than most other antidiabetic drugs.The most serious potential side effect of metformin use is lactic acidosis
,however this complication is very rare, and is generally reported in patients having associated severe liver or kidney disorders.

The episode of rapid and irregular heart beat doesn't seem to be due to the use of METFORMIN ,however you may discuss with your doctor if you still have some reservation or anxiety over using of METFORMIN,in lieu of your having SVT.
