Loop Monitor results

[Jwest626]

Hi, Just got back my loop monitor results and I was hoping that someone could shed some light on the results.
Little bit of back story, I had an ep study done back in November for bouts of SVT. The study was inconclusive and no ablation was done.

Dr. had me wear a loop monitor for 4 weeks and these are the results
Baseline transmission shows normal sinus rhythm at a rate of 97bpm. There were four events. The first one, the patient noticed a fast heart rate, light-headedness and dizziness. This occurred with normal sinus rhythm at a rate of 76 bpm and included a 4 beat run of SVT. There appeared to be P waves in front of each QRS with a 1:1 conduction. So this likely represented a short run of Atrial Tachycardia.

Next was an episode of the patient feeling a fast heart rate. This was predominantly sinus Tachycardia throughout most of the strip. The initial part of the strip appears to be SVT at a rate of 150bpm. The differential diagnosis here includes atrial tachycardia with 2:1 conduction as there does appear to be two P waves for each QRS versus atrial flutter versus simply baseline artifact, given the rest of the strip appears to be sinus tachycardia.

Next event was a feeling of fast HR. This occurred with sinus Tachycardia at a rate of 120bpm towards the end of the strip.

The final event was a fast HR occurring with normal sinus rhythm at a rate of 95 bpm. Within this, there was also a 4 beat run of SVT with no P waves present.

Can anyone break this down and tell me what it all means?

Jerry did a nice job of adding to the info.  Really you should be getting this interpreted by your doctor, that's the final word.

From what I'm reading you've got a twitchy artrium there.    Other stuff I can say is that even for experts it's sometimes hard to discern P waves when there's a fast heart rate going on.    Since this was from a holter monitor it will be even harder, since there are only 2 or 3 leads.  More leads=better resolution. So I wouldn't worry about missing p waves.  The tachy events were well under what anyone would consider to be too fast.

Good that you remain in sinus rhythm... some good news.

I believe if the fast rate is driven by the atrium, then an ablation could produce a cure.

As I understand it, our hearts were "designed" with a lot of signal generation redundancy and this can result in too many beat signals... tachy.  In the normal heart the sinus node filters out most of the "extra" signals, if it doesn't an ablation can/may block the "extra" beats from the atrium, resulting in more normal heart rates.

Others on this Community who suffer from PVC/PAC may be able to give you more inputs.
