[|Human|] my husnand woke up cold and shivering. He was well covered but needed more. this lasted for about 30 minutes then settled down about 2 hours later he woke and took his pulse which was quite rapid and unusual for him. His blood sugar is fairly normal as is his blood pressure now. What may have caused his shivers and rapid heartbeat? he is 78, weighs 65 k and is 6 ft tall
[|AI|]  Hello, Thank you for your query. This sequence of events usually occur before a fever develops. -Did you check his temperature at that time? -does he have any other signs of infection or any other symptoms?-any medical problems? Is he on any medications? Sometimes stress during the day can cause a transient increase in heart rate. If symptoms persists or recurs, please consult his physician for an electrocardiogram. Holder monitoring for 24 hrs may be required to catch the heart during such episodes to find out the rhythm abnormality. He may also need some tests to check for any chemical abnormalities in his blood that could be triggering these episodes If it doesn't recur, then don't worry about it. Fever can elevate heart rate as well. Next time Hope this helps. Please let me know if there is anything else I can help you with. Wish you both good health.
