Undiagnosed SVT ?

[BryanWoody]

Hi there..:I have over the past three 3 suffered from what I assume are 5 SVT attacks hr of 180-220 self terminating in no longer than half an hour heart rates have been caught in hospital but never on ecg  ...I have had a holter monitor ,echocardiogram , and blood tests besides a couple etopics all results have came back as some of the best my gp has ever seen ....my question would be I work in a very remote location no hospitals flight in and out only and I get major anxiety as to what the heart can handle especially with no access to a hospital my doctors do not seem concerned with treatment...in a healthy heart how long can a heart survive at the rate say I need to fly out to get treatment ...vagal manevers seem to have no effect

The reason I believe they think it is svt is the duration it lasted with no complications most of the time
Lasting around half an hour with a Bpm of around 180 ..on a side note I'm a 24 year old male othewise healthy like I said holter echo and blood work all came back normal with a history of anxeity

ER, not WE.  Sorry for the spelling errors.  Tiny phone keys.

Assuming that it is SVT, i would suapect that the reason no one is concerned is because your EKG looks normal.  This is typical with most types of SVT.  Once a physician actually sees an episode in action, then they sit up.  Mine called me at 10pm on a Sunday evening after I sent a recording from my 30 day monitor to the monitoring lab.  The key to the path of treating it, is for the physician to see it.  Mine would plead foe me to come to the WE for an EKG when it was racing, but I always slowed it down.  I would say that not knowing your age, an ACT event shouild not last more than a couple of hours before medical intervention.  The younger you are, the longer duration you can handle.  Because I was 60, my cardiologist dis not like my high SVT rates (240bpm) and urged me to get it treated.

Thanks for the advice !! It is hard to determine how far out of reach I will be I assume maybe 5-6 hours is the longest I would have to wait...honestly doesn't really seem like anyone's to comcerned after getting test results with moving forward say need be can a healthy heart handle being in svt for hours before being able to reach a hospital need be ?

I had SVT that would run on and on without terminating.  I had to intervene to terminate an event or it would keep going.  Fortunately, it was fairly responsive to Valsalva maneuvers, and I was always successful in eventually slowing it.  In the 54 years that I had it, my longest event lasted over 24 hours.  I was only 6 at the time, and it wasn't until my lips began to turn blue that my mother suspected something was wrong.  Throughout my life with SVT, I never did anything that would put me out of reach of a hospital.  My advice to you if your SVT does not respond to external methods to slow it would be to stay within hours reach of a medical facility that can deal with your condition. Ultimately, you should consider eliminating the problem through an electrophysiology procedure with ablation.  Good luck...
