What are Holter, Event and Transtelephonic Monitors?
What is it?
The Holter monitor, invented by Dr. Norman Holter, is a device that records heart rate and heartbeats (rhythm) continuously during a 24-hour period.
Event monitors are used to record heart rate and rhythms for brief periods. They work only when a person turns on the device.
A transtelephonic monitor is similar to an event monitor, but it sends the EKG to a recorder by telephone.
Why is it done?
The major purpose of a Holter monitor is to record your child’s heart rate and rhythm during various activities over a long period. If a problem or symptom occurs, you or your child can write the time of the symptom in an accompanying diary. This lets your pediatric cardiologist compare the symptom with the heart rate and rhythm during that specific time. The Holter monitor is most helpful when symptoms are frequent. It’s also helpful for showing changes in heart rate or rhythm that your child may not notice.
The major purpose of an event or transtelephonic monitor is to record your child’s heart rate and rhythm during a symptom (“event”). Your doctor may recommend an event monitor when symptoms are infrequent – for example, once per week or less.
How is it done?
The Holter monitor is a small tape recorder connected by wires to several patches called electrodes. These patches are put on your child’s chest. The tape recorder is in a small protective box that fits into a case with straps so it can be easily carried on the shoulder or waist. The electrical activity of the heartbeats travels through the electrodes and wires and is continuously recorded on tape, usually for a 24-hour period. You or your child will keep a record of activities in a diary. After the recording is done, the monitor and electrodes are removed. Then the tape recording is reviewed by a technician using a computer, and the heart rate and rhythm are transferred to paper. Your pediatric cardiologist will then review the recorded heart rate and rhythm and compare them with the diary.
Event monitors are small, portable devices carried in a purse or attached to a belt or shoulder strap like a portable tape player. When symptoms are infrequent, the monitors may be carried for several days or a few weeks. Most monitors are designed to record the heart rate and rhythm only when a button or switch is turned on. For example, when a symptom occurs, your child or another person would turn on the event recorder. The event recorder would then record the heart rate. Later, at a convenient time, the recorded heart rate and rhythm can be sent by telephone to a receiver in the hospital or clinic. Then your pediatric cardiologist can determine if there was a problem when the symptom occurred.
