What causes fast heart rate during aerobic exercise while having COPD?
Patient: Have COPD, 40 yr old female 5 2 exsmoker 20+ years 20 min aerobic exercise and heart rate climbs to 230-215 for about 10 mins after exercise and is very slow to decline, shaky and feel as though I could pass out with weird burping sensations too, overheated not any sweat to speak of ever either. Can weight lift but when cardio is involved I get the above result and feel as though I will die. Doctor: Hello,  It can happen as a side effect of bronchodilators.  However, it is better to get an ECG to rule out possible causes like cardiac arrhythmia.  Consult a cardiologist and he will direct you accordingly.  Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. Shinas Hussain,  General & Family Physician
