Heart and Circulatory System
Your circulatory system is made up of your heart, blood, blood vessels and lungs. In your circulatory system your heart pumps blood transporting nutrients, water and oxygen to your bodys cells. Your circulatory system allows your lungs to rid the body of waste and carbon dioxide and bring oxygen into your blood. Exercise and healthy eating are two ways you can help keep your circulatory system healthy. Smoking does damage to healthy blood circulation. When you smoke the carbon monoxide and nicotine entering your body have negative effects on your blood and blood vessels and constrict circulation. Signs of poor circulation include cold hands and feet, numbness, dizziness, migraines, varicose veins and pain in your feet or legs. Consult a doctor if you have these symptoms. Untreated, poor circulation can lead to stroke, high blood pressure, kidney damage and other diseases.
1 AnswerAn electrocardiogram (EKG or ECG for short) records the electrical activity of your heart. An EKG provides information about your heart's rate and rhythm. Ambulatory EKG monitoring is a type of EKG monitoring that allows you to move about while you wear electrodes and a portable recorder. Examples include Holter monitoring and ambulatory telemetry.
1 AnswerSome cardiac risk factors are within your control. By making positive lifestyle changes and/or taking medications, you can reduce or eliminate the risk to your heart from the factors listed below:
- High blood pressure (hypertension)
- High blood cholesterol (high total cholesterol, high LDL, low HDL, high triglycerides)
- Physical inactivity
- Excess weight
1 AnswerSome risk factors that affect your heart health cannot be changed. However, it's still important to be aware of them. Awareness gives you a chance to educate yourself -- and take measures to safeguard your health in other ways. Several of these factors are listed below.

- Age: Your risk increases with age.
- Sex (gender): The risk is higher for men of any age and for women after menopause.
- Family history (heredity and race): Heart disease tends to run in families and is more common in some ethnic groups.
- Personal history: People with past heart problems have more risk.
1 AnswerAlmost everyone diagnosed with Buerger's disease smokes cigarettes or uses other forms of tobacco, such as chewing tobacco. However, it isn't clear how tobacco use increases the risk for Buerger's disease. It's thought that chemicals in tobacco irritate the lining of the blood vessels, causing them to swell.

1 AnswerHeart-healthy eating should be creative and enjoyable, not an exercise in denial. As you begin to change your eating habits, try not to focus on what you're giving up. Instead, realize that with just a few small adjustments, you can continue enjoying your favorite foods. You'll also feel better and have more energy.
Remember: Heart-healthy eating aims to improve the quantity and the quality of your life!
Your healthcare providers may refer you to a registered dietitian (RD) to help you make changes to your diet. An RD can teach you about nutrition, help you choose foods and plan menus, monitor your progress, and encourage you to stick with your eating plan.
1 AnswerYour doctor will tell you how long to wear the ambulatory telemetry monitor -- this may be as long as 30 days. When this period is done, follow these steps:
- Return all the equipment, following the directions you were given with the equipment about where and how to send it.
- Call the center to make sure your study is completed promptly.
1 AnswerIf you faint, feel dizzy, or feel anything unusual with your heart during ambulatory telemetry monitoring, here's what to do:
- Stop what you're doing and press the button on your communicator. Pressing the button flags the data record. When the technician reviews the data at the center, the flag shows where to look for signs of heart rhythm problems.
- Call the center as soon as possible. With your equipment, you'll get a toll-free phone number to call any time you have a symptom. A technician is always available to gather more information about your symptom and connect it with the data from your monitor. If you can't call right away, take notes on the times you feel symptoms and call the center later.
1 AnswerHere are tips on how to take care of your ambulatory telemetry equipment:
- Change the battery in the monitor as needed. With your monitor, you'll get two rechargeable batteries and a battery charger. Each battery lasts 12 to 24 hours, and it's best to recharge one battery while using the other one. You'll hear an alarm beep when the battery needs to be charged.
- Charge the communicator while you sleep. With the communicator, you'll get a charger plug. One end plugs into the communicator and the other end plugs into a wall outlet. Plug it in nearby while you sleep (within 15 feet of the bed).
- Keep the equipment dry. Take the electrodes and monitor off before you swim, take a bath or take a shower. Put the electrodes and monitor back on afterward.
- Change the electrodes every day. Fresh electrodes will provide better information. Follow the directions provided with your equipment.
- If you have a pacemaker or ICD (internal defibrillator), do not put the monitor near it. Wear the monitor at your waist.
1 AnswerThe communicator for ambulatory telemetry automatically sends data to the medical center. This happens constantly, as long as you play your part. Here's what you need to do:
- Keep the communicator and monitor close to each other. If they are too far apart, the data can't be sent. You'll hear a beep alarm if the communicator is more than 15 feet from the monitor. It may help to keep the communicator in the same pouch with the monitor.
- Keep the monitor and communicator fully charged. Your data will not be recorded and sent if either the monitor or the communicator loses power.
1 AnswerThe following may happen before an ambulatory telemetry monitoring begins:
- Your doctor may do other tests. Along with a physical exam, your doctor will probably do an electrocardiogram (EKG or ECG).
- You'll get the telemetry equipment. If you can come to the hospital to pick up the equipment, a technician will attach the monitor and explain how it works. As an alternative, the equipment may be shipped to your home. If the equipment is shipped to you, you will need to call a technician once it arrives.
