Sir,
Male, 30, healthy lifestyle, chol. 4 mmol/l, BP 105/60, suffering from occational palpitations and anxiety.
Done the following tests: EKG stress test two times, echo two times, heart CT, a number of resting EKGs (one of them attached to my Medhelp profile) and 24 hour Holter, thyroid tests, electrolyte tests and blood count, all revealing excellent results. Good exercise capacity, completely normal EKG both during rest and exercise, appropriate blood pressure response to exercise and completely normal heart with good contractility and relaxation on echo. Holter revealed a few PACs, no significant tachy, brady, PVC or pauses.
Non smoker, no stimulants.
Medications: 25-50 mg Metoprolol/day for PACs and sinus tachycardia.
Did possibly have a short event of SVT during a panic attack in 2010, 5-10 seconds, not confirmed on EKG.
Now I am experiencing a new symptom, which is occurring more often if I am anxious, but it may happen without anxiety. I get a brief sensation in my throat, it may feel like a pressure in the throat, lasting 5-6 seconds, or it may feel like a tickling or fluttering sensation with the same duration, or just like a short pressure from below. Sometimes I just feel my normal heart rhythm in the throat very well. All those sensations happen more often if I sit leaning forwards.
It tends to stop before I am able to check the pulse, but the times I have felt something almost similar (not sure about this) while checking the pulse, it feels more or less normal, but I can not say this for sure (if the event I picked up felt completely similar). Sometimes it feels like air moving around in the esophagus, but I am not sure.
I am very familiar with the various sensation of PACs (also the early PACs pumping beating towards closed mitral valve) but the sensation is not similar. No other symptoms.
Could this be an arrhythmia?
If not, what could it be?
Can someone have brief SVT without reentry pathways in the heart?
Thank you in advance.
