  Now,   palpitations   are really common. And it generally appears as a fluttering in the chest, just about here. A bit like a sort of butterfly in there. Often last thing at night when you’re sitting quietly in bed you feel this and then there’s suddenly a (gasp) bit of a pause and a thump. And what that is, is there’s a pause in the pulse and then a big pulse after that. And that’s entirely normal. Occasionally it’s associated with diseases such as the thyroid gland. But rarely. And, occasionally, with drinking too much caffeine, so too much coffee. And you may get no symptoms of this. But, you get an irregular pulse. So what’s important is every now and then to check your pulse. Is it regular? If it’s irregular, then it’s sensible to see your doctor. Because what this is, is the top bit of the heart, the atria, are beating irregularly. A heartbeat starts when an electrical impulse is produced by the sinus node. This causes the atria, the top of the heart, to contract pushing blood

  We have two new risks for atrial fibrillation and an intriguing study on the duration of anticoagulation after bioprosthetic aortic valve. So first up is a study from the women's health initiative that, as we know, randomized women to receive estrogen, with or without progesterone, depending on whether they did or did not have had a hysterectomy. And this analysis looked over about a six-year follow-up period. To see the incidence of new atrial fibrillation that they found was modestly increased by about twelve percent overall, and this sum is a new finding, combined with other risks that have previously been seen of pulmonary, embolism, VTE and indeed cardiovascular events and so another factor to consider. When thinking about estrogen replacement therapy, next up is a study from the Framingham risk study looking at low magnesium, that was also seen to be a  risk factor for incidence of atrial fibrillation  looking at the lowest quartile. That is less than one point: seven, seve

  Atrial fibrillation is a cardiac arrhythmia, more commonly known as AFib. This is one of the supraventricular tachycardias. In a normal heart, the wavelengths of the electric waves are transferred from the SA node to the AV node in an organized manner. Once there is an organized conduct, passing from the SA node to the AV node, then it will be obtained concentrated or uniform conduction of atrial tissue. But with AFib, the wavelengths are a mess. Notice how fickle they are and go everywhere. Because this organized signal is lost, there will be no single abbreviation of the atria, instead, with these intermittent waves, there will be atrial spasms. In fact, it looks like there is a bag worms in the atria and they all move around, if you can imagine it. Also, the waves are doing their job, so they will signal the AV node intermittently, and this will lead to an irregular heartbeat, due to intermittent stimulation. They say that the classic ECF of AFib is incorrectly inconstant. What do
