Hello, I believe that would be a question for your doctor, but I can say that I have read that heart rates should be between 60-100 depending on age and activity, but I don't really know enough about it, best to hear from your medical care team. I had a lobectomy in 2000 and a wedge resection in 2021, the advances between my two surgeries have been amazing. When was your lobectomy and how are you doing? Were you staged yet and did your doctor send your tumor tissue out for mutation/biomarker testing to help formulate a treatment plan? Please feel free to share more, we are here to support one another. Wishing you all the best, Alisa, Lung Cancer Team Patient Leader
