Cardiac Myths and Facts

How well informed are you about cardiac devices? See if you can tell myth from fact. Take a look at these eight statements that Lifebeat Online has compiled and test your knowledge about cardiac devices.

Myth or Fact? My device is a cure-all for all my heart problems.

Myth. No device is a cure-all for any heart problem — a device is a treatment that can help you lead a more normal life. However, adopting a healthy lifestyle (including a moderate exercise program and a low-fat diet) may speed your recovery process and reduce or delay your need for further treatment.

Myth or Fact? If I'm touching someone and my ICD delivers a shock, that person will be shocked too.

Myth. If you receive a shock while touching someone, the energy from the ICD may pass from your skin to the other person. They may feel a tingle or a buzz, but not a shock.

Myth or Fact? I won't be able to use my cell phone or cordless phone.

Myth. Your implanted device is not affected by the use of cordless phones. A cellular phone, however, can affect a device's normal delivery of pulses if it is too close. You should keep the phone at least six inches from your implanted device. If it is a powerful phone (more than three watts), keep it a minimum of 12 inches away. You should hold your cellular phone on the opposite side of your body from the implanted device. But if the phone does come close to your device and your device malfunctions, simply move the phone away and the device will function normally again.

Myth or Fact? I can't have sex anymore because my elevated heart rate will make my device deliver a shock.

Myth. When you have sex, your heart rate increase is similar to what would happen during exercise. Your doctor can program your ICD system settings so that you can comfortably engage in a broad range of physical activities.

Myth or Fact? I will be able to get through the security system at an airport.

Fact. Some devices can set off airport security alarms, but they won't be damaged. You should, however, stay away from handheld security wands at airports. Just ask for a hand search. You can also identify yourself with a pacemaker/ICD identification card. Stents will not trigger security alarms.

Myth or Fact? Dental cleaning procedures will interfere with my device.

Myth. Routine dental drills and cleaning equipment will not affect your implanted device. However, you should be aware that your device may be affected by electrical currents, and electrocautery (electrical probe used to burn unwanted or harmful tissue) should only be used when your implanted device is turned off. Also, stay away from rooms with MRI equipment, as well as strong electrical or magnetic fields.

Myth or Fact? My implanted device has to be opened up in order to change the battery.

Myth. Actually, when your battery needs to be changed, a new device is implanted. Usually, though, the leads do not need to be replaced. Generally, the surgery takes about an hour. This is true for pacemakers, implanted defibrillators, and devices to treat heart failure.

Myth or Fact? I can use handheld massagers, electric blankets, and microwave ovens.

Fact. All three are safe and should not affect your implanted device. Also included on this list are radios, hair dryers, personal computers, printers, fax machines, and most other household appliances and office equipment.
