After implant surgery, you may experience redness, swelling, or soreness at the site. Limit movement of your arm and avoid heavy lifting so you don’t disturb the incision. Try to avoid any quick or sudden movements that might dislodge the leads. Your doctor will have a list of activities that you should avoid after your procedure. There might be a small lump under the skin where the CRT device is located, so avoid wearing tight clothing that could rub or irritate the skin at the implant site. Carefully follow your doctor’s instructions and keep your incision clean and dry.



The programmer lets your doctor program, reprogram, and test your CRT device. It takes measurements that your doctor can use to customize your therapy.




Some CRT-Ps and CRT-Ds come with a monitor that can transmit data from the device to your physician, so your device can be remotely monitored. Your CRT device can be monitored by your physician–either during an office visit or remotely with a home monitoring system. The process of checking your device is called an “interrogation.” It can transmit information on battery life and lead function, as well as medical data on your condition.

  • In-office monitoring: A programming tool is placed on your chest (you don’t have to remove your clothing) to collect information that will tell your doctor if you’ve had any irregular heart rhythms or if any electrical pulses or shocks were given.
  • Remote monitoring: Uses remote, wireless technology or analog landlines and transmitters to deliver information to your doctor by e-mail, fax, or phone. This allows your doctor to receive alerts and information on arrhythmia events, shocks delivered, battery status, and the condition of the leads. Some transmitters send data at set times, others allow data to be sent anytime, day or night. Transmitters can be placed in the home. Some devices require you to put a device over your implanted device, or otherwise interact to send information. One system is completely automatic. Ask your doctor what kind of remote monitoring system you may have, depending on the device you will have or have had implanted. Remote monitoring is not an emergency alert system.
