Does SVT sometimes cause seizures?

SVT. It can cause seizure if the heart rate is very fast & associated with significant drop in blood pressure.
Svt. no it should not, but rarely may potentially trigger an epilepsy episode in someone who already has epilepsy.
Maybe, but uncommon. Supraventricular tachycardia (svt) is a rapid heart rate of 150 beats per minute, or higher. A patient may feel he has a pounding heart. He may also be short of breath, breathing fast, or feeling dizzy. Fainting and having a seizure due less blood flowing to his brain, is also possible. If he has these symptoms for the first time, he should call 911 for an ambulance, and not drive to the hospital.
