Dizzy, bright shaky lights and Buzzing in ear

This is what I get sometimes when I have AFIB.

One Ablation 5 years ago, just had my second on Thursday, this time with a GA. Over the last 18 months I have been getting this dizzy feeling that causes me to shut my eyes and I hold on to something, I see white shaky lights and then i hear the buzz in my ear and it passes. This only lasts 2-3 seconds, sometime I get one every 30 mins for a few hours sometimes it lasts a lot longer, a few days it lasted all day and it was happening every 15mins. No pain just complete discomfort on the day that this happens. My heart rate seems to be around 47/48 normally and goes up to 90 without any rhyme or reason. They started 18 months ago and have been getting more frequent. I had my second ablation Thursday and thought that it was a great success as on Friday my rate was 58 and no dizzy turns all day. Yes I was tired and that carried through Sat and Sunday, unfortunately on Saturday the dizzy events started again but this time a had a few that lasted around 5 seconds and it felt like torture. On Sunday I had a few 5 second events and one cause me to collapse ( luckily the Laundry bag saved my head hitting the hard floor) Yesterday and today I have taken it easy and stayed in bed most of the day and no more dizzy events. All I can hope for is that it is settling down after the Ablation and my 48 bpm are now a fixture and fingers crossed the dizzy events do not return.

I just wanted people to be aware of my experience as I have never seen anyone report anything like this happening to them. The consultant doing the ablation had never heard of it before either. Perhaps they are not linked and just a weird coincidence, but I feel somehow that they are and I will now investigate that with the heart team as I do not want those dizzy spells. No driving for me until I find out the cause.

The only time I have had anything vaguely similar was during pre-syncope events when I felt about to faint. These were due to short pauses of my heart (maybe two/three seconds) mainly I think due to heart rate going too low. Seems I get this if HR drops below 55. Interesting as the ringing in ears is not something others have ever mentioned but I can recognise.

With that low of an resting HR, I would consult my Dr.That is a great number for an athlete, but if it ismedically induced, not so much.

Also Google "Bradycardia"

I had my second ablation in July this year. I did not have any pre-syncope events. Pre ablation my heart rate was around 80-120 bpm ,on the third day post ablation it went to 50 bpm. I was concerned so I phoned the GP. He said not to worry about it. After another 8 days it began to climb back up slowly and 7 weeks later averages 80bpm.

Hi Jock. Just waiting for my Cardiologist to ring in an hour or so for a telephone appointment. I'll be discussing pacemakers.This is because I've had quite a few of the 'grabbing something to stop from falling' incidents. The worst was in the street, when I had severe ringing in my ears as well. This lasted probably 7 or 8 seconds, maybe longer.

My understanding of this is that it happens at the transition point between af and reverting to sinus rhythm. There can be a short pause whilst the heart catches up with itself. When you don't always know when you're in af this can seem to just happen out of the blue.

My Kardia readings lately show the timing between beats to vary, and beats are sometimes so far apart they can cause light-headedness. Hence the chat about pacemakers.
