azithromycin and long QT

Hello everybody.I am male 31 years no heart problems or heart history problems in my family(this meaning my parents).
I have a serious problem .
3 days ago I took a single dose of Azythromycine of 1000 mg( 2 pills of 5oo mg taken all at once).
Now I am experiencing palpitations ,chest pain ...and tachycardia.I never had tachycardia before so I am guessing that all of the symptoms that I am experiencing are due to  Azithromycin .What should I do?How long will these symptoms last?
I am wondering what are my chances to develop a long QT syndrome after azithromycin?What is my real risk?
I have done an EKG and the doctor told me that I have a QTc of 434 ms...Is this normal?or is at the superior side of normal QTc?

Have you considered that whatever you're taking the Zithromax for could be the reason for your recent arrhythmia?  Have you had a prior adverse reaction to mycins? I'd report this to the physician that presribed the Z-pak and let him make the call.

Both are associated with cardiac arrhythimas, but is uncommon with Azithromax.  Definitely talk to the doc.

I was also just taking a 5 day dose pack of azithromycin for a sinus infection.  I started having heart palpatations as well.  I have tachycardia anyways so I didn't really associate it with the medicine.  It really started worrying me when my left arm started feeling weak and tingling.  This usually also happens when I have an SVT attack but it goes away quickly. This tingling lasted all day.  My heart palpatations were more frequent as well.  I did some researching about azithromycin and found it can cause heart palpatations.  I didn't take my last dose because I was scared too and the heart palpatations stopped.  My arm feels normal now too. However I'm still feeling dizzy.  I'm going to see my doctor today about it to see what he thinks. You should as well.
