Dnvrfox, I hope everything has settled down. I would like to chime in regarding your palpitations. I'm not a Dr, I'm a nuclear tech who has been working in nuclear cardiology for over 10 years, I am also advanced cardiac life support (ACLS) certified.

Based on your symptoms, it sure does sound like an abnormal heart rhythm, most likely supraventricular tachycardia (SVT) although I wouldn't rule out atrial fibrillation. Frequently these rhythms come and go so it's not umcommon to get a completely normal EKG when at your doctors office. Life threatening? Almost never. Curable? Almost always.

I do not think it's because you were vitamin deficient. What I would suggest is that you ask your Dr to refer you to a clinic where they will put on a 30 day Loop monitor also called Event monitors. It's about a pager sized device with two wires that stay attached to ekg leads on your chest. The way it works is that when you have a symptom, you push a record button and it records your ekg for about a minute. You transmit the recording to a 24 hr center and they can read your heart rhythm.

Frequently, rhythms like this can go into hibernation and not show their ugly head for long periods of time. A cardiology that specializes in electrophysiology is the one you should see. They can do ablation therapy (zapping conduction fibers in your heart) to cure these types of rhythms.

Best of luck
