Sorry, meant S wave but apparently had a brain fart. I have had problems with SVT before so I have several ECGs from my Dr to compare.
Hi!
You've posted your question both in the doctor forum and patient community. This is the patient community and we are not doctors.
That said, you don't have any slurring in your R waves. A slurred R wave is known as a delta wave and a sign of ventricular activation through an extra pathway (WPW syndrome), and a possible cause of SVT.
What you possibly mean is slurring of the S wave (downstroke on QRS complex). A slurred S wave can be a sign of so-called early repolarization, which actually often has nothing to do with repolarization, but rather in some cases, delayed depolarization, which some researchers claim is linked to a higher risk of dangerous cardiac arrhythmias (low, but still higher), if it's present in the inferior leads (I assume you've read this article).
Your S waves are not very slurred in my opinion, but I'm not a doctor, as I said.
What you may consider asking your doctor about, is your fairly marked ST depression and PR depression in your EKG. As you said "all of your 12-leads", is there a reason why you get so many EKGs registered? Do you have a known heart condition? A young female usually doesn't have blocked coronary arteries as a cause for ST depression, but you may want to ask your doctor.
Both males and females can have early repolarization. It usually goes away before the age of 40.
