I Have Been Having Strang Heart Pauses That Causes Several

I have been having strang heart pauses that causes several other symptoms including weekness, tingling in the extremities, near syncope, flush throughout body when the heart pauses and I have wore a heart monitor which indicated supra ventricular ectopic beats per cardiologist I last visited. I feel like it is more serious than he seems to think and I wanted another opinion. What does a supra ventricular ectopic beat mean and can it lead to something dangerous. I feel hat I haven't had a bad episode recorded and it has been hard to even get one on a monitor. My mother died from a stroke and had heart disease on her side of the family and I am worried it may mean more than it is showing up as.
