Patient's Query

Hi doctor,

My father is 71 years old and is type 2 diabetic with a history of glaucoma, high blood pressure, and cholesterol. For two days, my father has a cough and a heart rate close to 100 bpm. However, all other parameters like BP, sugar level and oxygen seem normal. His postprandial glucose level is 188 mg/dL. Currently, he is taking Metoprolol, Telmiride H, Glipizide, Rosuvastatin, and drops for glaucoma. Please advise if it is a matter of concern and its treatment options.

Hi,

Welcome to icliniq.com.

He is aged 71 years with multiple comorbidities, so his immunity is low. Currently, he has a fever and cough. Due to the fever, his heart rate is high. When fever subsides, the heart rate will go back to normal. There is no need to worry about the heart rate as it is normal for a heart rate to increase in a high fever. You can take an ECG (electrocardiogram) for him. Cough and fever are usually due to a chest infection. At this low-grade fever of recent onset no need for an antibiotic at this time. For fever, I suggest Paracetamol 500 mg thrice a day, and for cough, any Linctus or cough sedative can be given if cough is bothersome. You can take CBC (complete blood count), ECG, chest X-ray if fever is high with sputum production.

Investigations to be done

Do CBC (complete blood count), ECG (electrocardiogram), chest X-ray if fever is high grade with sputum production.

Patient's Query

Hi doctor,

Thanks for the reply. Can the heart rate go up due to extreme heat exposure or gas trouble? Please explain.

Hi,

Welcome back to icliniq.com.

Heat per se does not cause a faster heart rate, but heat and sweating resulting in dehydration may cause a high heart rate. Gas in the stomach itself cannot affect heart rate, but pain and anxiety can increase heart rates. Fever, infection in the body, inflammation, dehydration, thyroid disorders, anemia, exercise, fear, and heart rhythm disorders can cause the heart rate to go up. I hope this helped you.
