Hi, I am a 56 year old female just diagnosed with non-sustained ventricular tachycardia with no underlying heart disease. I have been taking allergy therapy for the past 4 years, 2 shots a week. I started getting tachycardia symptoms at the begining of the year. I had just switched over to taking allergy drops because the shots have not been totally effective after all this time. An hour after taking the first drops I got a strong run of tachycardia (six seconds) with pre-syncope symptom. I had just started wearing a heart monitor and this event led to my diagnosis.
I have read that an ingredient in the shots and drops, phenol, can cause heart problems. The drops have 0.4% phenol, I am not sure about the shots. Is there any evidence of the possibility of a link between my allergy therapy and my development of VT?
Thanks very much!!
