Help needed interpreting a Kardia report

The odd “quivering” heart sensation which I have now had for about 6 days continues every night. When I awoke this morning I took a Kardia reading whilst it was taking place and sent it off to Kardia for analysis. The finding is reproduced below. The bradycardia is known to my GP and cardiologist and so is not of direct concern-it is the intended result of taking Sotalol and is my “normal” rate at this time of the morning. However, the Ist degree AV block is a completely new item for me. It is stated that it need not necessarily be of concern, and it apparently means that the heart is conducting electrical current slowly, but I wondered if anyone could expand on that a bit, or knows if it might be relevant to the nightly “quivering” sensation?

RESULTS

BRADYCARDIA

The slow heart rate (bradycardia) may be caused by you being particularly fit, or taking a medication such as a beta blocker. It may also be abnormal, particularly if you have symptoms such as dizziness or faintness.

SINUS BRADYCARDIA

Your heart is beating normally but you have a slow rate of less than 60 beats per minute. This is known as sinus bradycardia. If you have symptoms of any sort that concern you you should consult a medical professional.

1ST DEGREE AV BLOCK

There is a longer than normal delay in signals being conducted from the top of your heart to the bottom chamber; this is rarely serious and if a lone finding, may be left untreated.

NO VENTRICULAR ECTOPICS OBSERVED

A ventricular ectopic (VE) is an extra beat originating in the bottom part of the heart. You have none which is completely normal.

NO ATRIAL ECTOPICS OBSERVED

A atrial ectopic (AE) is an extra beat originating in the top part of the heart. You have none which is completely normal.

NORMAL QRS PATTERN

The QRS morphology indicates how the bottom part of the heart (ventricles) contract. You are within normal limits

I think many of us with AF past or present will have 1st degree AV block so not of concern. Some drugs such as flecainide can do this as well.

Thanks!

Sam - I cannot help with AV block but your analysis report sounds positive and it's great that you could record during the shivering phase. You now have something which you can discuss with your cardiologist and get his/her opinion.
