I am 70 years. I am diagnosed as COPD, RLL Bronchiectasis and Emphysema. Now ECHO suggests Grade 1 LVDD. Bronchodilator and cortisone nebulisation prescribed along with theophylline oral. My normal pulse rate at rest was 85 to 90. Now it will go upto 130 for some time in a day and later settles at 90. What steps I should take live with minimum comfort as long as I live, say one or two years.
