Hello, my name is Khalia.I am contacting you regarding a question about food poisoning related to tachycardia.I am 18 years old have been diangosed with Neurocardiogenic Syncope after a positive tilt table test.The weird thing about this is my symptoms appeared suddenly of June of last year after a bout of food poisoning.Even though I have no prior health conditions related to my heart.I went to a Subway restaurant and got sick after eating contaminated mayonnaise.But after a day my symptoms left,so I never felt the need to seek treatment for food poisoning.But soon after I began developing symptoms of rapid heartbeat upon walking, lightheaded,hot flashes etc.I soon went to multiple physicians without any answers that lead me to my diagnoses by my cardiologist.And I have had a holter monitor test that showed an abnormal heartbeat (tachycardia). I have had various tests done that showed no direct problems with my heart that require attention.I am currently taking Propanolol 60 mg and Fludrocortisone 0.1 with little to no relief of my symptoms.Is this just a coincidence or is there a connection to food poisoning?

Summarized question: Is food poisoning related to tachycardia?
