Question: On the 25th of October I was admitted to A&E with sinus tachycardia and elevated BP, it disappeared my stats went to normal and I was discharged back to my GP. On the 26th of October, I was admitted to A&E, again, with sinus tachycardia and high BP, it disappeared, and I was discharged back to my GP. On the 27th of October, I was admitted to A&E with sinus tachycardia and elevated BP, but with a temperature of 40.5 degrees Celsius accompanied with acute diarrhoea. I was given IV antibiotics and IV fluids and discharged with a diagnosis of gastroenteritis. Since then my heart rate has been erratic and elevated sometimes above 100 but not more than 120 and my temperature is 38 degrees Celsius continuous. I have had investigations done with my cardiologists, which shown in a 24 hour tape second degree AV block type 1 twice in the 24 hours. Stress echo and 24 BP was normal. My questions are could an infection cause the erratic and elevated heart rate?
