Information for Patients


Cardiac Arrest

Also called: SCA, Sudden cardiac death

The heart has an internal electrical system that controls the rhythm of the heartbeat. Problems can cause abnormal heart rhythms, called arrhythmias. There are many types of arrhythmia. During an arrhythmia, the heart can beat too fast, too slow, or it can stop beating. Sudden cardiac arrest (SCA) occurs when the heart develops an arrhythmia that causes it to stop beating. This is different than a heart attack, where the heart usually continues to beat but blood flow to the heart is blocked.

There are many possible causes of SCA. They include coronary heart disease, physical stress, and some inherited disorders. Sometimes there is no known cause for the SCA.

Without medical attention, the person will die within a few minutes. People are less likely to die if they have early defibrillation. Defibrillation sends an electric shock to restore the heart rhythm to normal. You should give cardiopulmonary resuscitation (CPR) to a person having SCA until defibrillation can be done.

If you have had an SCA, an implantable cardiac defibrillator (ICD) reduces the chance of dying from a second SCA.

Ectopic Pregnancy

Also called: Abdominal pregnancy, Tubal pregnancy

The uterus, or womb, is the place where a baby grows when a woman is pregnant. If you have an ectopic pregnancy, the fertilized egg grows in the wrong place, outside the uterus, usually in the fallopian tubes. The result is usually a miscarriage.

Ectopic pregnancy can be a medical emergency if it ruptures. Signs of ectopic pregnancy include

  • Abdominal pain
  • Shoulder pain
  • Vaginal bleeding
  • Feeling dizzy or faint

Get medical care right away if you have these signs. Doctors use drugs or surgery to remove the ectopic tissue so it doesn't damage your organs. Many women who have had ectopic pregnancies go on to have healthy pregnancies later.

Tumors and Pregnancy

Tumors during pregnancy are rare, but they can happen. Tumors can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. The most common cancers in pregnancy are breast cancer, cervical cancer, lymphoma, and melanoma. Cancer itself rarely harms the baby, and some cancer treatments are safe during pregnancy. You and your health care provider will work together to find the best treatment. Your options will depend on how far along the pregnancy is, as well as the type, size, and stage of your cancer.

Another type of tumor that women can get is called a gestational trophoblastic disease (GTD). It happens when a fertilized egg doesn't become a fetus. GTD is not always easy to find. It is usually benign, but some types can be malignant. The most common type of GTD is a molar pregnancy. In its early stages, it may look like a normal pregnancy. You should see your health care provider if you have vaginal bleeding (not menstrual bleeding).

Treatment depends on the type of tumor, whether it has spread to other places, and your overall health.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
