What is a radical neck dissection? when is it done?

What is a radical neck dissection? The surgeon removes a block of tissue from the collarbone to the jaw and from the front to the back of the neck. The large muscle on the side of the neck that is used for rotating, flexing or extending the neck is also taken out, along with the major vein on the side of the neck. Sometimes, a less drastic operation, called a supraomohyoid neck dissection is done. This takes out only the lymph nodes, the tissue surrounding the nodes and a muscle at the front of the neck. Another technique, called a functional neck dissection, saves the muscles of the neck, taking out only the lymph nodes and tissues surrounding them.
What kind of incision is made with a radical neck dissection? The incision depends upon what the surgery is for. It can run from below the ear to the collarbone. Everything in the front of the neck on one side or on both sides may be removed. This may include the lymph nodes, blood vessels, nerves, and the salivary gland under the jawbone.

How serious is a heart arrhythmia? Why arrhythmia happen?

My husband has an arrhythmia. Is that serious?

Arrhythmias are a disorder of the rhythm of the heartbeat, which can sometimes be life threatening. Atrial fibrillation (in the upper chambers of the heart) is a type of arrhythmia that can be either converted to normal rhythm with an electrical shock to the heart or slowed by medicines. Atrial fibrillation results in an irregular pulse, usually at a pulse rate between 100 and 140. Any rapid, irregular heartbeat requires medical attention within a few hours. Atrial fibrillation becomes more common in people over fifty years of age. The real cause of atrial fibrillation is usually unknown, but some cases occur in people with overactive thyroid glands (known as thyrotoxicosis). Atrial fibrillation is not the result of coronary artery disease, but it can aggravate preexisting congestive heart failure, which itself is often caused by coronary artery disease.

An arrhythmia affecting the lower chambers of the heart (the ventricles) is very dangerous. The body can withstand ventricular fibrillation for only a few minutes before death occurs. Ventricular fibrillation is thought to be the immediate cause of most sudden deaths from heart disease. An arrhythmia, such as ventricular fibrillation, is almost always the result of a heart attack, usually occurring within minutes after the heart attack begins. The closure of a heart artery by a clot (the cause of a heart attack) deprives the heart muscle of blood and oxygen, triggering the ventricle to fibrillate and losing its capacity as a pump as a result.

What is the most common type of arrhythmia?

There are many different types of arrhythmias. Recent research has shown that diets containing omega 3 fats (such as flaxseed, walnuts, grape seeds, pumpkin seeds, sesame, salmon, tuna) will decrease the occurrence of sudden death due to arrhythmias. Some arrhythmias are the result of coronary artery disease, some result from transient “insults” to the heart from alcohol or drugs like cocaine. Certain arrhythmias in young people are due to inborn defects in the heart’s complex electrical system. Any unusual type of heartbeat deserves medical attention so that a diagnosis can be made.
