[|Human|] I suffer from Bradycardia. This has been since 2004 when I underwent an Ablation for Tachycardia. My normal heartbeat is between 39/45. My blood pressure is slightly high - 157/80. I am 51, a non smoker and hardly ever take alcohol. I have been exercising 5 days a week for nearly a year now. I weigh 12 stone and am 5ft 9in. During exercise I feel short of breath until properly warmed up, but my recovery time is just around a few minutes or less. At rest I often get chest pains. I also take Ranitidine - 150mg once a-day, for Acid reflux. I have also noticed that I keep having reoccurring slight head aches when resting. I am worried that my Bradycardia is getting worse as my heart-rate is slowing down as time goes by. Can you offer me a diagnosis on this information?
[|AI|]  Your bradycardia needs evaluation. You should undergo holder monitoring and exercise cardiac stress test. If your response to exercise is satisfactory you may not need any treatment. If heart rate response to exercise is poor with significant Brady on holder. You may need pacemaker. Your chest pain may be non-cardiac which will be proved in exercise stress test. If stress test is abnormal then you may need further cardiac evaluation.
