What are abnormal heart rhythms called?

Arrhythmia. An irregular heartbeat is an arrhythmia or also know as dysrhythmia.
Arrythmias. This term is often used to describe heart rhythms different from a normal sinus rhythm.
An arrhythmia. Abnormal heart rhythms (arrhythmias) are caused by problems with the electrical system that regulates the steady, rhythmic beat of the heart. The heartbeat may be too slow (bradycardia) or too fast (tachycardia); it may remain steady or become chaotic. Some arrhythmias are dangerous and cause sudden cardiac death, while others may be bothersome but are not life threatening. See PCP ASAP.

What is an electrical shock delivered to the heart to correct abnormal heart rhythms called?

Defibrillation. If it's a potentially fatal heart rhythm (eg ventricular tachycardia or fibrillation), it's called defibrillation. In this case, a large amount of energy is delivered directly to the heart to stop it so that the internal pacemaker can re-activate it to a (hopefully) normal rhythm. In all cases, CPR (chest compressions) are required as well.
Cardioversion. If non-fatal (like atrial fibrillation), it's cardioversion in which a lower energy & specific electrical phase is given with the patient sedated but awake so that the rhythm can be converted to the normal, sinus rhythm.
Cardioversion-defib. An implantable aicd has cardioversion and defibrillation capabilities. However, usually, it delivers a defibrillatory shock when it detects a dangerous rhythm. Of course, the energy is much lower since less tissue needs to be penetrated (the electrical lead goes directly into the heart).

What is the name of an electrical shock delivered to the heart to correct certain abnormal heart rhythms called?

Cardioversion. Cardioversion is the name of the electric shock delivered to the heart to 'reset' abnormal heart rhythms or arrythmias.
Two names. Cardioversion and defibrillation are both terms used for the electric shock to correct abnormal rhythms. Defibrillation is a specific term for the termination of ventricular fibrillation.

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.

Does the guardian system detect abnormal heart rhythms?

Yes and much more. The angelmed guardian system is an implantable st segment monitor. It is designed to detect an imminent heart attack or decrease in blood flow to the heart with exercise. It will also detect changes in the heart rhythm such as atrial fibrillation or premature ventricular contractions.

Which diagnostic tests are used for abnormal heart rhythms?

Several. An EKG to see what the exact rhythm is and to look for other abnormalities. A history and physical examination. You may have a heart murmur or appear pale if you have anemia for instance. Blood tests to exclude anemia or an overactive thyroid gland for instance. A holter monitor to catch and record the abnormal rhythm. An echocardiogram to evaluate heart function and the valves.
EKG. An electrocardiogram, also known as an ekg is used to identify the rhythm of the heart- normal and abnormal ones.
