Finally, a doctor listened to me!

I don't know if anyone else has had a problem with a rapid heart rate during and after chemo and radiation. but this has been an ongoing problem for me. I have been mentioning it to my oncologist for the last few months and he just keeps saying "it will get better". My resting heart rate has been 100-115 and when I walk (slowly), it goes up to 120-150 and I also get short of breath. They did an ECG a while back and it showed a normal ryhthm and tachycardia. I went to see my reg doc last week because I wanted her input on this. She followed me around with a pulse oxy meter and my O2 dropped the higher my heart rate got. Within a couple of minutes or less, my heart rate was over 150 and the O2 was in the low 80's. She wanted me to see a pulmonologist and possibly start on O2. I told her I wanted to think about it and see what my oncologist thought. I emailed his nurse coodinator with the info about the heart rate and O2 level....Lo, and behold, I got a response immediately. He wants me to see the pulmonologist that works with LC patients tomorrow. I guess sometimes you have to advocate for yourself a bit harder in order to get attention. I think it will get better too, but it is preventing me from regaining strength and if there is anything I can do in the short time to facilitate that. I will do it. I didn't have this problem before the LC and I have not had surgery....inoperable Stage 3a with a para aortic lymph node involved.
