Can digitalis be used for abnormal heart rhythms?

Yes. But it's not a first line medicine any more because there are newer, more effective medicines. It's still sometimes added to others though.

Is digitalis used to cure abnormal heart rhythms?

No. No. Digitalis also referred to as digoxin can be used to treat symptoms of abnormal rhythms such as atrial fibrillation. It may help keep someone in a normal sinus rhythm or help control the ventricular rate. While it may help with symptoms, digoxin does not "cure" dysrhythmias. In fact, like most anti-arrhythmic medication, it can-especially at high doses- cause dysrhythmias.
Ask a cardiologist. Digitalis has a long history of treating congestive heart failure by stimulating the heart muscle. I believe it is used in patients with heart failure but with a normal sinus rhythm.

When is? Digitalis? Used to cure abnormal heart rhythms?

Never. Digitalis is used to control the ventricular rates of some abnormal fast atrial arrhythmias or svt. In atrial fibrillation it is utilized to control the fast rate. It does not "cure" the problem nor does it actually prevent the atrial arrhythmias, as antiarrhythmic medications would.

Digitalis cure? Does digitalis cure abnormal heart rhythms or just treat it?

Digitalis. Digitalis does not cure abnormal heart rhythms, but can help stabilize the heart rhythm or heart rate. This medication is derived from the foxglove plant, and is one of the original western pharmaceuticals. In addition to the beneficial effects on heart rhythm, digitalis can also help the heart contract more strongly for patients with heart failure.
Not a cure. Digitalis is a medication that can improve some abnormal rhythms. The benefits it provides are only while receiving the medication.

Do abnormal heart rhythms decrease blood delivery?

Depends. It depends on the type of dysrhythmia and the rate. For example, atrial fibrillation with a heart rate in the 70-80s may cause no symptoms at all. A rate in the 150's may decrease blood pressure because there is not adequate time for the heart to fill between beats. A heart rate lower than 30 may cause a low blood pressure because the slow rate. Symptoms often relate to total cardiac output.
Potentially. The pumping of the heart is the mechanism by which blood is delivered throughout the body. If a abnormal heart rhythm affect what is known as the cardiac output, it can definitely affect the delivery of blood throughout the body. Thank you for the question.

Why do abnormal heart rhythms cause nausea?

Vagal Response. In general, most cardiac rhythm disturbances will not cause nausea. However, there is a condition that can cause both nausea and arrhythmia (particularly slow heart rate), and that is called a vagal response. This is an abnormal reflex response which causes the heart rate to abnormally slow, and also has concurrent symptoms of nausea and/or "cold sweats" and/or lightheadedness.

How do you define abnormal heart rhythms?

Ekg. Simple office test that can determine the rhythm of the heart.....Many different types of rhythm, not all are serious but exact definition is very important.
Depends. An abnormal heart rhythm is one that beats too slow, too fast or irregular. I would suggest seeing your primary care physician or a cardiologist for evaluation.
Arrhytmia. Any abnormal heart rhythm is more acuretly called a dysrhthmia which ranges from benign extra beats to more lethal heart rhythms that require medications or defibrillators to treat.
Many different types. A normal heart beat is regular like a clock ticking. There are many different types of abnormal heart rhythms. The heart rhythm could be either too fast, too slow or have some type of irregularity or skipping. Some of these abnormal rhythms are not serious. Some irregular rhythms are potentially dangerous. The best way to check is call you doctor and have an ekg or heart monitor performed.

What are the tests for abnormal heart rhythms?

Tests for arrythmias. After physical exam an ekg will determine the arrythmia most of the time and 24 hour holter monitor may be needed in some cases. Some abnormal heart rythm may require electro physiological studies, echocardiogram and coronary angiograms in some cases.

What are the symptoms associated with abnormal heart rhythms?

Abnormal heart rythm. There are many different abnormal heart rhythm with varying symptoms from cest pain, palpitation, dizziness, headache to syncope. There are basically two kind of abnormal heart rhythm tachyarrythmia (rapid heart beat)and bradyarrythmia (slow heart rate)different arrythmias have different symptoms.
Thanks for asking! There are many different types of abnormal heart rhythms. Symptoms associated with abnormally fast heart rhythms include the sense of a racing heart, dizziness, difficulty breathing, sometimes a fluttering feeling in the throat or chest, and occasionally fainting.
