Atrial fibrillation?!

Atrial fibrillation?

Thanks for the helpful answers received at my earlier posting. I am sorry to go on about my atrial fibrillation but I am very confused. I went into hospital at 11pm with my usual atrial fib and tightness of neck & jaw, heart beat 129pm. Five hours earlier I had taken 5mg beta blocker, 100mg flecainide and warfarin. In hospital they gave me oxygen and digoxin. My monitor through the night showed me to be in sinus rhythm at 119 bpm (my normal being 50bpm). My GP says I can’t have been in Afib with sinus rhythm. Everything felt the same as Afib. Could the extra medication have reverted my heart into sinus rhythm but not have affected the rapid heart beat which slowed gradually during the night. It usually stops suddenly. If not Afib then what did I have? Beta blocker now increased and statin also, so sounds like A fib to me. I do like to know what is going on and worry if I don’t know.

Thanks Gary V. My betablocker is bisoprolol and I take 5mg in the morning and 5mg in the evening. I was told that I am already on the high end of medication. Flecainide is 100mg am and 100mg evening.
The cardiologist in hospital said that I also have angina. Another doctor talked about AFib as if I had it at the time and said they were now coming in clusters ( 3 times in the past 5 weeks after a gap of 6 months) and would now get more frequent and may become permanent.

Perhaps I am not explaining myself well. Usually Afib comes on suddenly, very strong, very fast, very irregular and I can feel the beats everywhere. This time only sign was tight neck/jaw. Felt pulse, put on bp monitor - 129 bpm. I didn’t catch on that the beats were regular this time, (although looking back I think they may have been regular 2 weeks earlier when the same thing happened and I couldn,t feel them in the usual way. I had to stay in hospital that time, too). This time after an ECG I was given oxygen through the nose and put on a potassium drip, also unusual for me, so I guess things were different from usual when I just have ECG’s every hour until I go back to normal rhythm. Confused? So am I.

It's really scary, isn't it.
Your heart goes into an abnormal rhythm called an atrial fib. Then after O2 and time it "converts" to a normal sinus rythym. The treatment of choice to prevent this is Digoxin and Beta blockers. You are very blessed that you convert back into a sinus rhythm. Some people have to be shocked or defibrulated which really hurts. Some people will convert on meds which is what you are seeming to do.
Potassium will help with arrhythmias if they are caused by low Potassium.
As horrible as this feels and as hard as you heart pumps when it is in a fib, it is less dangerous than some other irregular heart rhythms. If you do have a diagnosis of A-fib from a doctor who has seen you in this irregular rhythm, then ask him why he hasn't put you on Digoxin (lanoxin). That is the treatment of choice for this problem and it will prevent it in most cases.
