What Causes Pressure In Chest Along With Rapid Heart Rate?

hi, I had been experiencing some left chest pressure, not pain but pressure as well as a feeling that my heart was racing while I was sleeping prompting me to take some aspirin. Could not get a beat on my chest, but my next artery was pumping at a slower pace than I felt my heart if this is possible. I went to doctor about a month ago and she said that it could be Helicobacter Pylori. But after doing the test it came back negative. She proceeded to follow up with a full physical and blood work and EKG. Cholesterol came in very high at 260, HDL at 34 very low, and LDL could not be measured because TRiglicerides were 414 and too high to measure LDL. EKG came back with a Sinus Rhythm, abnormal Left Axis Deviation, Left Anterior Fascicular Block. I am 44 years old/male, 5 11 and 193 lbs. Usually pretty athletic, but not so much in past 2 months. Also I have been really stressed out because I am out of work due to legal issues as well as my girlfriend stressing me out everyday about getting married and having kids.
