Low Atrial Rhythm

Hi, I'm about 15 and a half, and i recently found out from an EKG that i have a low atrial rhythm. My doctor instructed me to go and set an appointment up with a cardiologist to have it further evaluated. I would like to know what exactly a low atrial rhythm is, what kind of effects it has on people, and if I should be alarmed.

Low atrial rhythm most likely isn't coming from the natural pacemaker which is located in the high atrium.  It is normal to have this as long as you are not limited in terms of your physical activity such as climbing stairs, running or playing with your colleagues.  If that's the case I would not worry about this at all.  On the other hand, if you do notice some limitations, a visit to a cardiologist may not be a bad idea.  He would do history and a physical exam and evaluate your heart function with an echocardiogram.

I just googled it and a cardiologist wrote this.

A low atrial rhythm refers to where the heart's pacemaker is located. There may be several different pacemakers and when the rhythm is coming from one lower in the atrium it is refered to as a "low atrial rhythm".  NSR means normal sinus rhythm and atrial escape rhythm refers to a slow atrial rhythm.  All of these are normal.
