Some common types of cardiac arrhythmias include:
- Sinus node dysfunction: usually produces a slow heart rate (bradycardia) or less than 50 beats per minute. The most common cause is scar tissue that develops and eventually replaces the sinus node. It is unknown why it happens. Sinus node dysfunction may also be due to coronary disease, hypothyroidism, severe liver disease, hypothermia, typhoid or other conditions. Can also be due to increased vasovagal tone, an unusual activity of the vagus nerve.
- Supraventricular tachyarrhythmias: This diverse family of cardiac arrhythmias causes rapid heartbeat (tachycardia) that originate in areas that are above the ventricles. In most cases, the fundamental problem is an abnormality of the AV node or the presence of an abnormal pathway resulting in the typical path of the signals of the heartbeat.

Its name is in full swing cardiac arrhythmia or abnormal heart rate.
In normal adults, the heart beats regularly at a frequency of 60 to 100 times per minute and pulse rate (which can be felt in the wrist, neck or other body part) coincides with the powerful contractions of the two cavities the heart’s lower chambers, called ventricles. The two upper chambers of the heart, called atria, also contract and help fill the ventricles. Read the rest of this entry »
Treatment
Spider veins do not require treatment. In some people, compression stockings may reduce the size of existing spider veins and help prevent the appearance of more. The two most common cosmetic treatments to remove spider veins are sclerotherapy and laser.
- Sclerotherapy: injecting a saline solution directly into the affected area, which makes spider veins disappear. The area may be sore for a few days and could be bruising, which should disappear in a few weeks. Could take several sessions of sclerotherapy. Injections can be slightly painful.

Symptoms
Blood vessels usually appear red or bluish purple on the legs or thighs, and in the face, forearms or hands. In general, spider veins cause no symptoms, but in rare cases may cause mild discomfort but continuous or burning sensation.
Diagnosis
Your health professional can diagnose spider veins just looking at them.
Duration
Spider veins may be permanent or may disappear by themselves after a few months, especially if they are caused by pregnancy or certain medicines. Read the rest of this entry »
The superficial veins of the legs, sometimes called “spider veins” occur when a group of tiny veins are concentrated beneath the surface of the skin and cause pigmentation of red, blue or purple. These spider veins are named for the way they acquire pigmentation. In some cases, spider veins are much lower in others are more obvious, which could acomplejar the person. However, spider veins are harmless and are usually treated only for aesthetic reasons.
Spider veins occur most often in the thighs, ankles, calves, and are more common in women than in men. Not clearly understood what causes each of the cases of spider veins, but may be a hereditary problem. Some cases are related to pregnancy, use of contraceptive pills or excess weight.

Treatment
Treatment depends mainly on the size of the aneurysm. The larger the aneurysm, the greater the chance of breakage. Emergency surgery for a ruptured aneurysm involves a higher risk of death than elective surgery.
It is generally recommended surgery for aneurysms in beginning to leak. It is recommended in people with aneurysms larger than 5.5 cm in diameter, unless there is another disease that involves a big risk for surgery. Even without symptoms, almost always was to carry out emergency surgery for a person with an aneurysm 6.5 cm higher.
People with smaller aneurysms may not be operated but must have an ultrasound every 12 months for those with aneurysms smaller than 3.5 cm and every six months for those with aneurysms larger than 3.5 cm. These tests are performed to see if the aneurysm grew. Read the rest of this entry »
Duration
Once an aortic aneurysm develops, it is a lifelong condition. Most of these aneurysms grow over time, and are expanded at an average rate of 0.33 cm to 0.5 cm per year.
Prevention
By controlling risk factors like high cholesterol, high blood pressure, smoking and diabetes can reduce the risk of developing an aortic aneurysm. If you have high cholesterol, eating a diet low in fat and cholesterol and, if necessary, take medication to lower cholesterol. Read the rest of this entry »
