For the first time, last year I experienced SVT. The first episode lasted for about 5 hours, and the second attack lasted for 7 hours. Both times I was admitted to Hospital. I am interested to find out how long these attacks can last.? I believe that I read of someone having an attack which lasted for many weeks. Any comments would be appreciated. Thanks.

My first attack lasted for 2.30 hours and reverted at home without any medical intervention, but left me quite alarmed as you will be able to relate to. Since then I have had 13 other episodes. Three of these lasted for periods of 5.15 hours, 7.25 hours and 10 hours and I ended up in the ED where they reverted normally. On one occasion they tried Adenosine which stops/starts the heart but this did not hasten the reversion. On all other occasions my attacks have lasted for periods of 50 minutes to 2.20 hours. When I now get an attack I take 50mg of Metoprolol, and if that doesn't work within an hour, I take a further 50mg Metoprolol, and up until now that has reverted my heart rate to my normal, which is very low at about 48-50bpm. I have not had an attack since July 2013 and have my fingers crossed that I will not have another attack in the immediate furture. You are young and I hope that they can eventually sort this out for you. At my age I have high blood pressure and arrythmia which is being controlled by the usual 'poison' that they prescribe. Good luck Scott.
