Dizziness, numbness in hands. Abnormal ECG report. Bradycardia?

I recently went for an ECG and had an long QT 534mm, an rsr` in the v1, bradycardia. My family physician has referred me to a cardiologist. I have had ECG before and have never had issues and this has never been seen. I have never fainted but sometimes when I stand up fast I get dizzy and sometime get numbness in hands, arms mostly when I am not doing anything ( i have low BP)

I am an active, healthy 33 year old female. I am 5'7 and 130 pounds. I workout daily but have stopped running because I wasnt sure what these findings mean. Should I be concerned.

Cardiologist 's  Response
Dear Ma'm
Thanks for writing to us.
ECGs are best interpreted when you actually look at them. like in your query the QT of 534 has no relevance unless i know your heart rate which you have mentioned to be slow. Moreover the character of Rsr' in V1 can not be ascertained without looking at it. So i request you to see your cardiologist and proceed as per his advise. since you do not have any major symptoms as yet , so do not panic. feel free to discuss further.

Cardiologist Dr. Jorge Brenes-Salazar's  Response
The QT interval has to be corrected for heart rate, since you had bradycardia then this has to be taken into account, and calculated manually. This is very important, since it is paramount to distinguish between a long QT interval and one that just "looks long" to the reading computer. The pattern that you describe is that of a right bundle branch, usually benign. That is the question I would ask you cardiologist, what is my CORRECTED QT interval.
Hope that helps.
