How To Calculate Heart Rate In Atrial Fibrillation
100 to >200: definition of VT is rate 100 or higher and origin from bottom chamber, R or L. Rate of VT depends on the reason for VT, level of adrenaline, stresses on heart such as blocked artery, etc. Slow VT would be closer to low 100's and fast VT closer to 160-200. There are other types of tachycardia coming from upper chambers and the middle of the heart, AV node ...Read more
Can a paroxysmal atrial fibrillation and av node reentry tachycardia increase the risk for a heart attack?
Stress reduction: If the high heart rate is really due to stress reduction, and you don't have an abnormal arrhythmia which can also be induced by stress hormones, then relaxation and stress management techniques should help. Also avoid caffeine, alcohol, tobacco, and stimulants, in order to minimize the stress response. See your doctor for evaluation to make sure it's simply stress and not something else. ...Read more
When looking at EKG can a doctor tell the difference between fast heart rate due to anxiety, and fast rate due to vtach, afib, and other heart issues?
Yes: For the rhythm issues you listed, one can easily tell by 12 lead ECG. They are other abnormal rhythms that are more difficult to discern. ...Read more
All increase: Exercise causes an increased demand for blood flow to provide oxygen to the muscles doing the work. This is accomplished by increase in heart rate and stoke volume. Since cardiac output is determined by heart rate and stroke volume, it also goes up. Blood pressure also typically increases with strenuous exercise. ...Read more
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
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
Depends...: There are heart rhythmn disorders that do not begin with an elevated heart rate. Not all cardiac arrhythmias are due to an elevated heart rate. There are rhythmn disorders that have a normal heart rate or even a slow heart rate. A normal or slow heart rate does not rule put an arrhythmia. ...Read moreSee 2 more doctor answers
