Hello,
Quick question: In my EKGs (at least those I've seen since I learned to interpret them), I see Q waves, especially in lead III. They are about 0,2 mv deep, slightly above 40 msec wide, they seem to change a bit, possibly due to my breathing. I can see small, narrow Q waves in V5 and V6 too, and narrow Q waves in lead II and AVF (less than 40 msec wide, but they are about 0,15 mv deep).
No Q waves in other leads.
As I said, they change a bit, most EKGs are stamped "normal" but one of them was stamped "old MI".
My R progression through the precordial leads is perfect. I'm 28 years old and healthy, I can't believe I've had a heart attack! Got echo and Holter/stress EKG done 10 months ago, nothing pathological found (except some PACs).
I also have somewhat pronounced R and S "spikes" in the precordial leads. My cardiologist said they were normal in healthy, young, somewhat nervous people, and they change with adrenaline (though my adrenaline levels are usually high when taking an EKG, my BP raises to about 150/90 from 110/60). R (V1) is about 0,6 mv, S (V1) about 2 mv and R (V5-V6) 1,5-1,8 mv.
My cardiologist(s) just say my EKG is normal. My GP sais I should stop focusing on my EKGs (and he's probably right).
What can cause the mysterious Q waves?
Thanks again :)
