I am a first year medical student and I have been practicing with ECGs. For some reason i was pretty nervous about it and my heart rate was slightly higher than usual (90bpm - not really worried about that). However i did notice that the p wave on lead II was slightly wobbly. It still followed its normal shape but it was just a bit wobbly. Everything else seemed normal. I was just wondering if this is a problem. Could we have slightly misplaced the electrodes to give this wobbly reading? Was my nerves a factor in this? Should i get a proper ECG done by a professional? I am a healthy 19 year old with no medical conditions and am not overweight or anything. I know this probably isn't the place to be asking this question but i just wanted to get some opinions on it.
I have uploaded a photo of it, i only had a small part of it.
