I have an on and off mild pain sensation throat my left arm which sometime accompanied with pricking feeling nd numbness below elbow region since 1 year. When exercise it gets better temporarily. I used turn in sleep and sleep on this arm mistakenly which made it numb many time. But I corrected the posture since few months. I check blood pressure regularly at home on Dr. Morepen device bp result and pulse rate always shows normal but shows irregular heart beat symbol ((?)) 6 out 10 times, which made me worry. I also feel slight heaviness on my chest and breathlessness after stairs. I am look fit and athlete built 36m/180 cms/82 kgs. Exercise for 30-40 mins at home with dumbbell nd barbell for 4-5 days in a week. No history of heart problem in family. Do I have heart issue? How can I check and ensure my heart health in this lockdown situation.
