I am 41 years old with a family history of heart problems (relatives dying from a heart attack) recently I started having a lot of what felt like flip flopping going on for 3 weeks the doctor said it was pvcs. These were happening all day and night waking me up, I felt wore out. I have been having mild chest pain of and on for several years  but usually it goes away. about 4 months ago I went hiking and had chest pain, and pain accross my shoulder area and into my jaw was aout of breath. I rested awhile and it went away. 2 years ago the ultrasound saw the lower right heart valve staying open I also had low blood pressure 86/ 65 at the time. I recently had a stress test done, during the test my heart rate kept dropping back down. They couldnt get it to 160 and the tech had to push on my back to keep me in place on  the tredmill. After the test I had mild chest pain that lasted acouple of minutes. I was exhausted the rest of the day and woke up this morning not feeling well.  normally after vigorous exercise I am wore out for the day.  I have been having tingliness in the left side of my face, dizziness, headaches if I sit in one place like at the computer or just sitting I get dizzy and feel sick. almost seems like my b/p drops while sitting. The doctor said the pvcs were harmless. Why am I having all these symtoms? Is this an indicator that something more serious can be occuring?
Don't worry and need not panic.... just need to take care... frequent PVC's need treatment...and surely can be done. If at 160 heart rate You’re stress test negative then ok. . No need of further investigation at present... Just do regular exercise and increase your stamina... Need more detail to guide you better
