Atrial Fibrillation And Stroke

Atrial fibrillation occurs when the normal, regular, synchronous action of the upper chambers of the heart becomes chaotic, rapid and inefficient.

Some who go into atrial fibrillation know it right away because they feel bad-they feel what we doctors term palpitations:their heart beating rapidly or irregularly (fluttering). They may have other symptoms associated with this such as dizziness, chest pain or shortness of breath. Many, however, go into atrial fibrillation and are not aware of it.

The first symptom they feel may be a stroke due to a clot developing in the upper chambers of the heart dislodging and going down an artery to the brain,

TIAs and silent atrial fibrillation. Sometimes strokes present in unusual ways, like the inability to differentiated a spade from a diamond when playing bridge and afib is often the cause.

Foxglove Equipoise. When William Withering began treating patients suffering from dropsy in 1775 with various preparations of the foxglove plant he wasn’t sure if he would help or hurt them. After 240 years of treatment, we are still unsure if rhe drug obtained from foxglove is useful.

  1. What about paroxysmal atrial fib, normal heart, liw cholesterol of 150, low bp 100/68, no diabetes. Not obese. Women of 66 with L-thyroxine treated hypothyroidism. Walks two miles a day. Normal echocardiogram
    Recent dx of ductal carcinoma insitu and lumpectomy.
    She is in Eliquis.
    What next? Is there a non drug way? The EP cardiologist wants to add Flecainide.

    1. Teepu,
      I hope soon to publish my post on maintaining normal rhythm for afibbers. It is a complicated topic.
      A common question is “is there anything I can do?”
      Recent evidence suggests that if you are overweight, losing 10% of body weight helps lower recurrence of AF.
      If drinking more than 1 alcoholic beverage today you should cut down. Make sure your thyroid levels are normal, your potassium is >4 and your magnesium >1.9
      Be aware of personal triggers: most of the time afib begins randomly but for some a specific good, or caffeinated beverage or a very stressful experience will set off AF.
      If episodes begin during sleep, consider testing for sleep apnea.
      If considering drug therapy, flecainide is a good choice for you as your heart is structurally normal. Well tolerated, no long term side effects and reasonably effective. You should get some assessment for coronary artery disease prior to starting.
