<s>[INST] Hi, may I answer your health queries right now ?  Please type your query here...I have emphysema and I am having  a rapid heart rate of 135 after walking a block. I am 55 yrs old and am fit. Should I see a doctor and is there some meds I should be taking? [/INST] Hellothanks for posting here. Rapid heart rate in emphysema is usually caused due to the inhaled bronchodilators you are using. But they are very essential for your emphysema. Another group of medications commonly prescribed in emphysema can cause rapid heart rate. These are aminophylline group of medications (deriphylline, theophylline, acebrophylline). You can try stop aminophylline group of medications for some 5 days. Or alternatively you can start tab abroad or tab coral an 5 mg two times a day.in addition to this I would advise you to take a cardiology evaluation. Thank you </s>
