I too have seizures.... I have been to many neurologists cardiologist and I finally found a Dr who new what tests to do and for how long... I would only b sent home w a three day monitor..... But in your normal daily routine it can be very hard to carch in just three days so I was only diagnosed w palipatations.... This new dr had ke wear a monitor for a month I had several episodes where I feel lightheaded pass out and some times go into a seizure... Friday this dr preformed an ablation on my heart and I havent had an episode so far crossing fingers. I was apparently born w two circuits which was adding extra heart beats and making me pass out.... It takes time for this vircuit to mature before it can be found Im 25 so they said mine developed very early some arent found until their 50's..... Idk where you live but if your in dallas tx area look up Dr Brian Le..... Hes the best
p.s., did they ever determine the cause for the acute tubular necrosis?
I haven't heard of a cardiac arrhythmia causing a seizure either. If an arrhythmia causes problems with blood it can cause someone to blackout. It's not common on this board to hear someone report that they turned blue even when they've had a blackout (syncope).
Why is arrhythmia suspected in the last seizure, because he turned blue?
Who was around him when he had the seizure?
cardiac arrhythmias don't cause seizure; at least not to my knowledge and I worked in the cardiology field and have been to MANY cardiac arrests. I have never seen any patient in any kind of arrhythmia having a seizure. Pre-syncopy and pure syncopy, yes, but never a seizure. Could the medicine he was taking have this affect? Did he take this medicine for awhile, while all of this was happening, and then came off the medicine and improved? You really need to think about this. A rate of 150, if originated in the atrium, may make him a bit lightheaded, but those rates aren't bad, his normal rates would be much higher than that playing sports. If the rate originated in the ventricle, that may be a different story. I would consider asking for him to have a 48-72 hour Holter Monitor put on or better still a King Of hearts Monitor put on to wear for 30 days where he can record his heart rate when he has these symptoms.
I am not a doctor but I have done my own research on arrhythmias and I haven't really come across much on seizures resulting from arrrythmias. There is a lack of proper blood flow to the body and brain when one is in tachycardia but if the rate only goes to 150 I see that as minimal. Has your son been tested for epilepsy? Has he been tested for autonomic dysfunction? I do hope you find your answers.
