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

I'm getting these episodes of chest pain and heaviness on my left side that go down to my shoulder and arm, and they last a really long time, like more than a day. They happen randomly without any exertion, and it's scary. I had an ECG during a panic attack, and it showed a heart rate of 130 bpm with sinus tachycardia, but I was discharged after 12 hours. Another time, I felt that chest heaviness with a burning sensation again, and the echocardiography came out normal. The doctor said there's nothing to worry about cardiac-wise, but the anxiety and fear are hard to shake off. Should I consider a stress test or something, even though my ECG was normal at that rate?
