What Is The Reason For Irregular Heart Beat And Has Diagnosed For Esophageal Spasms?

I have these episodes where my heart will stop beating very briefly then its almost as if only one side beats once very hard then continues. My heart rate constant picks up and slows down. It doesn't do much when I'm doing something. It does it frequently when I Relax and when stressed. The time of day, diet, full or empty stomach doesn't matter. My heart looks healthy and nothing showed up when I did a stress test. They say it is because of esophageal spasms. When I have a mislead episode I feel short of breath, I get spells of being dizzy or vertigo. I have problems getting warm abduction staying warm, I am almost always tired, and have issues with +3 +4 pitting adema. I'm only 31, could all this really just be due to esophageal spasms or am i right when I think something else is wrong?
