hi guys, yesterday i had a very abnormal event happen. i was relatively anxious as i felt a common, day to day ectopic beat whilst bending down. i decided to workout gently a few hours later, still with a slight fear of developing one again. everything seemed fine, but post workout, i felt a little dizzy and within a 5 or 6 seconds my heart started racing considerably to an estimate of 160/170bpm. maybe even higher. i layed down on the floor, dialed 999 and was telling myself this MUST be ventricular tachycardia, to happen this fast and make me this dizzy. it lasted all in all around 40 seconds or so and then my heart rate started dropping quickly, within a minute or so, i felt a normal slightly elevated heart rate, and was left severely dizzy and tired. i had a ecg 4 hours later at hospital and it showed nothing what so ever concerning. I have had a stress test in 2015, a echocardiogram in 14, aswell as multiple holter monitors! only things noted were a few pvc's and sve's

Syncope is one of the magic events that turns something low risk into something high risk.

Now that you've experienced that its vastly more important to be thoroughly evaluated. Especually since you've had concerns about lqts.

Remember concern for lqt is over 500 msec OR symptoms like syncope.

As for tachycardia, the fact that it resolved in a few minutes signals a smaller reentrant circuit, vt is typically a faster rate but sure its possible.

Back to cardiology then..

Torsades of course isnt outside the realm of possibility though, pvcs tend to occur the most in the post exercise period, so if an r on t phenomenon were to occur it would be then. Torsades occurs in short bursts like that.

You can request the cardiologist run a "Epinephrine stress test" to unmask it to be sure.

Just tell him you've had issues with it on ecg before and you're concerned for "concealed lqt1" and suggest a "mayo protocol" if they don't typically run them.

Also a standard chemistry panel for electrolytes and a "cardiokey" (14 day holter) if they have it available.

Event monitors are good to wear too, but if they can do a cardiokey thats just vastly superior technology.

An evebt monitor requires you to hit a button when you feel symptoms and it transmits a 20 second strip, 10 seconds before the button 10 seconds after.

Problem is theres often more then 10 seconds lag between the actual rhythm, feeling the symptoms and hitting the button..

Cardiokeys are 14 day holters that send everything for 2 weeks.
