ECG

In my early 20's I had an ECG with the following findings:rate:atrial 84, vent.84,rhythm sinus,intervals:pr 010,qrs 066, r-t 033 and in leads avf and 3 qrs complex (as well as p and t wave) going upward like in lead 1,but now  when I am (male) in my late 40's qrs complex is going downward in leads avf and 3 with st segment first being horizontal and  than going up like in t wave.Five months ago I had an ecg with the following findings:rate 89,pr 167, qrs 90, qt 324,qtc 394, axis p 22, qrs -1,t 46.Normal sinus rhythm rate 89.....Normal p axis,pr, rate&rhythm.Artifact in lead(s) 2,3,avf.Last week I had an ecg with the following findings:vent rate 76,duration p 134, qrs 88, intervals pr 166, qt 344, qtc 372, axes p 73, qrs 4, t 25.sinus rhythm within normal limits summary:normal.Although all the above ecg are normal what causes qrs complex to go downward in leads avf and 3 with st segment first being horizontal and than going up like t wave?Does an old heart attack cause qrs complex to be like that in leads avf and 3? What does artifact in lead(s) 2,3,avf mean?Does the position of a patient (lying,standing)when ecg is taken cause qrs to go downward?Does age have anything to do with the above findings and was there big(significant) ecg change from ealy 20's to late 40's?Thanks

Dear Long,

The changes you describe may occur as a result of a number causes. To give an accurate explanation I would need to visualized the ECG. I would recommend discussing the ECG changes with your doctor who has both ECGs in front of him/her. This approach would provide you with the most concise answer to your questions.

Thanks for your question,
