Afib: What causes an episode? What if I don't notice?

Posted by dfelix @dfelix, Jan 27, 2019

yesterday I had episodes of afib. I was just laying down when my heart started beating fast. Over 100 beats per min, What are possible casues of these occurances?

For all with A-Fib that is related to caffeine use, please note that a lot of cosmetic products, shampoos, etc. often have caffeine. I have a friend who avoided caffeine in her diet but if she had a little in a skin product it would set her off into an A-Fib episode. I did not know that these products have caffeine but some do so it's good to watch the labels.

@hopeful 33250 and all, I have A-fib and I drink coffee, and I have no reason to say that the caffeine causes an A-fib incident. Some of us sneak by, apparently. My particular case may be virtually unique — 1) I have no conscious feelings of an irregular heart beat (although EKGs show it every time; 2) after a small stroke 20 months ago (attributable to A-fib), deficient brain performance (mainly muscular mobility) led to therapy for re-teaching my brain to function better and more reliably. Part of that is brain stimulation from a cluster of stimuli — one of which is caffeine. My consumption of coffee is limited to a cup in the morning and (sometimes) a cup in the evening, nothing like the gallon a day I used to consume at work. From my perspective, my advice to anybody with A-fib or Ventricular-tach should make caffeine consumption a major issue to discuss and regulate with a medical team that includes an electrophysiologist and a neurologist. A few of you — like me — might benefit from limited caffeine consumption. Martin

I rarely notice when I am in A-Fib as well. Mine is naturally occuring so having had it my entire life it's a bit 'normal' for me not to notice. I am usually only aware when I have a new EKG or when my heart sort of seizes up for just a moment like it's pausing to hold it's breath and flops like a fish out of water. That one I notice. I was diagnosed with A-Fib and also Postural Tachycardia Syndrome. Mayo can do a tilt table test that will be able to record whether or not certain positions cause you to jump into A-Fib. I simply started taking the Metoprolol and was very lucky that the first med I tried works perfectly.

@dfelix, as you get more responses and do internet searches you will find there are many A-fib triggers but what causes the condition in the first place is still somewhat a mystery. In my case it seems to be caused or triggered by an excess of thyroid hormone. I have been hypothyroid (underactive thyroid, not producing enough hormone) to I have taken either Synthroid or a natural desiccated thyroid extract. If one's TSH gets too low, A-fib can result. Although this may not be your problem, it never hurts to have your PCP do a thyroid workup and at least eliminate that as a potential problem. God bless.

I have low thyroid, and I have A-fib. I now take Dofetilide and have not had any real problems in about 5 years. I almost always awoke to an episode.I am very thankful for the Dofetilide.

Check with your doctor, they always have samples.. Drug companies also offer assistance programs. No harm asking.
