Can Hypertension Cause Atrial Fibrillation
Yes: Atrial fibrillation is an irregularly irregular heart rhythm , it can happen when the atrium( upper chamber of the heart) is enlarged. Hypertension causes the heart to work harder, develops hypertrophy to have enough force to push the blood forward from the ventricle ( lower chamber of the heart); the atrium in turn enlarges to push blood to ventricle and eventually dilates then a-fib develops. ...Read moreSee 1 more doctor answer
Atrial fibrillation is an irregular and often rapid heart rate that commonly causes poor blood flow to the body. During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms include heart palpitations, shortness ...Read more
Which is better and more safe in general for treating hypertension and atrial fibrillation metoprolol succinate or bisoprololesp. If s.creatinine1.56
Neither. In clinical: trials, carvedilol has significantly better outcomes than either metoprolol (e.g. 3%/yr lower mortality rates continuing for many years) or bisoprolol. Creatinine is quite another issue, produced by all muscle cells, yet used to crudely estimate renal filtering function, not the 4 known responses to carvedilol. Yet the clinical trial data for all the Beta blockers is as augmenters to ACEI agents. ...Read more

2 mechanisms : First - high blood pressure increases the pressures in your heart and left atrium which triggers the pulmonary veins to fire and send out electrical signals that can short circuit the heart. Second - long standing hypertension dilates the atria and causes fibrosis which makes it easier to short circuit those chambers and stay in atrial fibrillation. ...Read moreSee 1 more doctor answer

Grandmother has atrial fibrillation am i at increased risk? I have sinus tachycardia and high blood pressure
Tough call: You're asking a good question that's hard to answer. 3 million people in the us have atrial fibrillation, and of those, ~30% have at least 1 family member with afib. But because there's so much afib out there, and because the prevalence is so high in advanced age (8% at 80yrs, 16%+ at 90) it's hard to decide what the specific risk due to any given family member is. ...Read moreSee 1 more doctor answer
Atrial fibrillation + high blood pressure 141/87. On 4mg warfarin INR 3 / 5mg amlodipine 5mg bisoprolol for 3months. Why isnt BP going down.What risks?
Compensation: Sometimes when you start BP meds, the kidneys compensate in an attempt to maintain the (too high) BP. Add a mild diuretic like hydrochlorothiazide 25 mg (cheap as water, gentle, you won't even know you're taking it) and I'll bet you'll see your BP fall nicely. Your INR is perfect! ...Read more
What are the causes of atrial fibrillation and can it be transient. I am a 60 yr old male with treated hypertension and elevated cholesterol.?
We don't really know: Af can be due to normal wear and tear as occurs in HTN and the aging process. Aging causes insertion of non-conducting tissue (scar) between normal heart cells which is bad. All old people get this but not all old people get af. Why? We know that nests of cells fire crazily at times triggering af. These nests are frequently located in pulmonary veins. But why, and what triggers them? ...Read moreSee 1 more doctor answer
