Can you have atrial fibrillation with a slow heart rate 60-100?

Can you have atrial fibrillation with a slow heart rate 60-100?

Yes: atrial fibrillation is when the atrium is beating not in coordination with the ventricle. It beats around 200 beats a minute. If the ventricular rate is controlled it beats 60-100 beats a minute. Since the are not synchronized there is a higher risk of blood clots in the heart which then can be thrown to the brain causing a stroke. N that is why we use blood thinners. ...Read more

Heart Rate (Definition)

Heart rate is a measurement of the number of times a person's heart beats in one minute. Normal heart rates vary with a person's age and with excitement and exercise. Abnormal heart rates are too slow, too fast, and/or irregular (too much ...Read more

If I have a history of atrial fibrillation and tachycardia is it bad that my heart rate has been 144 all day?

If I have a history of atrial fibrillation and tachycardia is it bad that my heart rate has been 144 all day?

Yes.: If the heart rate is elevated for prolonged periods of time, there is a risk for tachycardia-induced cardiomyopathy - or weakening of the heart from rapid heart rates. This is usually reversible once the heart rate is corrected. You should see your cardiologist for evaluation. ...Read more

My husband's atrial fibrillation seems to have progressed. He's breathing very rapid and loud while sleeping, has higher heart rates, sick sinus syndr?

Sleep apnea and AFib: There is a well known association between hypoxemia (low circulating oxygen in blood) and stress on heart manifesting as arrhythmia. In ur husbands case, loud breathing may be snoring. Have him see a reputable pulmonologist for eval and treatment of sleep apnea if he has it. Treat underlying cause of what may be worsening his AF. Cardiologist ought to coordinate with pulmonary doc. ...Read more

How accurate is a bloodpresure monitor if used to measure my pulse rate while I have an attack of atrial fibrillation? Does it miss any heart beats?

How accurate is a bloodpresure monitor if used to measure my pulse rate while I have an attack of atrial fibrillation? Does it miss any heart beats?

Depends: Some monitors may miscount if you have a very fast irregular pulse but it'll probably be accurate. There are a number of other apps you could use to correlate, or do it the old fashion way: feel your pulse in your neck (or wrist) for thirty seconds and multiply by 2. ...Read more

Atrial fibrillation: Is very common. 25% of all people over the age of 40 have atrial fibrillation. Almost 1/3 of all over age 65 have it. Certainly coronary artery disease can be an etiology (excluded by your stress test) but there are many other associated causes. Obesity and obstructive sleep apnea are highest associated issues. Many treatments are available. See your health care provider for evaluation. ...Read more

Can a car accident cause atrial fibrillation in your heart?

No: Our best understandings of afib require that the heart muscle have undergone changes over a prolonged period of time to enable afib. While it's possible the stress of an accident could have "set off" an afib attack, if it sticks around, you were likely at risk in the first place. A truly severe wreck can bruise the heart, but the fib would pass as the bruise heals. ...Read more

Always had heart palps, had tests years ago all normal. Lately palps increased. Can Atrial Fibrillation just develop? Or do you always have it?

Atrial fibrillation: AFib can 'just develop'. If you have anxiety disorder, it will magnify any minimal extrasystoles you may have. There are many monitoring devices, event recorders even implantable but your doctor can best evaluate whether you need aggressive attempts at seeing if you have an arrhythmia and what it is. ...Read more

What medicine is good for atrial fibrillation and a, slow heart beat?

What medicine is good for atrial fibrillation and a, slow heart beat?

It depends: Upon what else is going on - what is your blood pressure, how slow is the pulse, does it ever go fast; do you have heart failure or sleep apnea. if your heart goes so slow it bothers you, and there is nothing correctable, the only solution is a pacemaker. ...Read more

Is an irregular heart beat most commonly atrial fibrillation or something else?

Is an irregular heart beat most commonly atrial fibrillation or something else?

Partially yes: The most common irregular heart beat is sinus arrhythmia which is a respiratory variation in the regularity, a perfectly normal heart rhythm and not indicative of any disease. The most common abnormal heart irregularity is atrial fibrillation, with some 2-3 million people having this heart rhythm. ...Read more

My heart has this weird beat to it; could it be atrial fibrillation?

My heart has this weird beat to it; could it be atrial fibrillation?

Sure - why not: At your age, atrial fib would be a bit unlikely, but yes, it could certainly be a culprit. The other respondant is correct in stating that we need to capture this on an ekg or a wearable monitor to correctly identify its nature. There should be a good electrophysiologist in galveston if you want to investigate further. ...Read more

Does taking magnesium help with heart palpitations and atrial fibrillation? How does it take work after taking it? "

Does taking magnesium help with heart palpitations and atrial fibrillation? How does it take work after taking it? "

Complex, Mixed Data: All muscle cells water inside & outside separated by fat (~30% cholesterol: stabilizes & allows movement without tearing) membrane. Proteins in membrane pump na+ ions out, k+ ions in, along with other ion movements. Other proteins suddenly change this: allow na+ to go in & k+ out ~0.001 sec later. Inner membranes keep ca+2 away from contractile proteins to stop contraction. ↑mg+ may ↓irritability. ...Read more

I had PVCs on my 48hr heart monitor, but nothing from the atrium. Does that mean no atrial fibrillation?

Atrial fib: The monitor did not pick up any evidence of atrial fibrillation during the 48 hour period you wore it. It is still possible that you could have had episodes of atrial fibrillation at other times, but from the information at hand there is no proof of that. ...Read more

O've had two heart surgeries as a child and had an ablation for atrial fibrillation. How often should I see my cardiologist?

O've had two heart surgeries as a child and had an ablation for atrial fibrillation. How often should I see my cardiologist?

Visit returns: Frequency for re checks really depends on the problem (s) and the symptoms. Not knowing what your surgeries were or the success of the ablation it is hard to say. If all has been repaired and no symptoms and sinus rhythm are stable, then yearly visits would likely be fine. If you're having problems, then they would dictate the frequency of return visits. ...Read more

Will daily exercise, eating healthy and not smoking protect my heart from things like atrial fibrillation as I get older and other heart issues?

It will help U-: In general 2 B much more healthy, but A-fib can occur in the healthy as it is more a genetic predisposition than Ur diet & exercise. But by all means don't stop what Ur doing or worry about it. If it happens in later life, it is not a sudden fatal episode, but 1 the comes on suddenly but can B treated &/or converted. ...Read more

Having atrial fibrillation, I do not feel fast heart beat or shortness of breath, due to medication. Would air travel for 6 hours be a problem?

Having atrial fibrillation, I do not feel fast heart beat or shortness of breath, due to medication. Would air travel for 6 hours be a problem?

C Below: You have asymptomatic Afib. Depending on your CHADS2 Score or CHADSVASC you should be at least on Aspirin. My guess is that you likely should be on Warfarin also.
- Air travel is as safe as staying at home watching a TV Show. What is important is your antiplatelt therapy or anticoagulation as needed. ...Read more

In what situations, other than atrial fibrillation (having to do with the heart-not dvt) would a patient be on IV Heparin? For example, preop for CABG

In what situations, other than atrial fibrillation (having to do with the heart-not dvt) would a patient be on IV Heparin? For example, preop for CABG

IV heparin: IV heparin can be given for multiple reasons such as MI (heart attack), DVT, Pulmonary Embolism, Atrial Fibrillation, Mechanical heart valves, Other thromboembolic diseases. In certain situations patient are on outpatient anticoagulants which may need to be stopped during preop and IV heparin is initiated. Unsure what the reasoning in this situation is. Hope this helps. ...Read more
