  5. I'm 18 and just got my ECG results which say sinus arrhythmia but I don't really understand what that means. My heart rate is 75 bpm, P is 97 ms, PR is 117 ms, QRS is 98 ms, QTQTc is at 352395 ms, and there's something about RV5 and SV1 being at 2.7031.245 mv. They noted it's a normal ECG, but I'm still a bit worried. Should I be concerned about any of these numbers?

Your ECG report indicates a normal heart rhythm with a diagnosis of sinus arrhythmia, which is a benign condition characterized by a variation in heart rate with breathing, and all other parameters, including PR, QRS, and QT intervals, are within normal limits, suggesting no underlying cardiac abnormalities, so you can be reassured that your heart is functioning normall
