Hi, My mom is 79 years old. She had an aortic valve replacement back in January, a full hip replacement in July, takes over 17 various meds including seroquel and quetiapine. She wants to be independant however I am becoming more and more concerned about her safety. Numerous times when I have gone to visit her I find pills either on her bed or her bedroom floor, pills I believe to be Rx not OTC. (Sorry, I m off topic...) Tonight s question is about heart rate.... Her heart rate is running at 136. What is a reasonable range for heart rate?
