Had to get an ECG for work (but not really any "opinion" with it, it was done at a sports medical clinic. All came back "normal", but my PR int and QRS duration were both at the longer end. (206ms for PR, 108ms for QRS).
Any heart experts care to comment on there being any point in looking deeper?
You might want to point out to both your work and the "medical" clinic doing the ECG the sheer pointlessness combined with the potential for unnecessary anxiety and/or wasting of your time caused by doing a test without any clinical interpretation or advice to follow on from it.
As you've already recognised, the PR interval is long, so technically first degree heart block. The QRS is very slightly long. In the right context these might be normal variants, but that depends on the interpretation of the rest of the ECG (not the automatic "report" you get which is notoriously unreliable), your symptoms, medical history, age and a whole bunch of other stuff that no-one should be attempting over the Internet.
Sorry, it's probably not what you're looking for but the answer is (as it is so often): see your GP if you're concerned.
