4Ambulatory MonitorsAmbulatory monitors are small, portable electrocardiograph machines that are able to record the heart’s rhythm. Each type of monitor has unique features related to length of recording time and ability to send the recordings over the phone
5Ambulatory Monitors assess heart rhythm over time correlate symptoms with heart rhythmdiagnose abnormal heart rhythms:what kind they are, how long they last, and what may cause them guide treatment for abnormal heart rhythms
7Holter Monitor (also called Ambulatory ECG) A Holter monitor is a portable ECG recorder that is worn during normal daily activities, including sleeping. It can be worn up to 24 hours.
8Holter MonitorElectrodes are placed on the skin of the chest. Wires are attached from the electrodes to a box about the size of a portable tape player and worn on a belt or shoulder strap. The electrical impulses are continuously recorded and stored in the Holter Monitor
9Holter MonitorThe patient is asked to keep a diary of activities and symptoms, such as fluttering feelings in the chest (palpitations), rapid heartbeats, and any episodes of dizziness or faintness.
10Loop Recorder (also called an Event Recorder) This device, similar to a Holter monitor, is worn during normal daily activities including sleeping; however, it is worn for a longer period of time. It can be removed during showers and baths. It is used for arrhythmias that occur less frequently.
11Loop RecorderWhen the patient feels symptoms, they depress a button and the recorder is activated. The monitor records the event for the 60 seconds prior to pushing the button and up to 40 seconds after the arrhythmia is over. The loop recorder can store up to three events.
12Loop RecorderThe rhythm can be sent immediately or saved and transmitted later, over the phone line. The technician will give the recordings to the doctor for review. If the reading indicates an emergency, the technician will instruct the patient to go to the emergency room
14CardioNet (Mobile Cardiac Outpatient Telemetry) CardioNet mobile telemetry allows continuous heartbeat monitoring as the patient goes about daily activities. Most people are on the CardioNet service from 7 to 14 days.
15CardioNet (Mobile Cardiac Outpatient Telemetry) This device consists of a small sensor attached to three electrode pads, worn on a belt clip. The sensor sends each heartbeat to a handheld monitor that can be tucked into a pocket or purse.
16CardioNet (Mobile Cardiac Outpatient Telemetry) When the monitor detects a heart rhythm problem — whether the patient feels it or not — it automatically transmits your ECG to the CardioNet monitoring center. A cardiac technician analyzes each transmission, responds appropriately to each event and transmit diagnostic reports to the doctor.
18Transtelephonic Transmitter Transtelephonic transmitters are not worn continuously.They are used only during the phone- monitoring period. In the past, this type of transmitter was used for monitoring pacemaker function.However, now it is used for patients with arrhythmias to monitor certain events indicated by their doctor.
19Transtelephonic Transmitter The electrode may be a finger electrode, wrist bracelet or chest plate. The patient dials the center and places the telephone into a transmitter. After the transmission is completed, the nurse or technician will ask questions about the patient’s symptoms and current medications.
21Electrocardiogram (ECG or EKG) The ECG is a device used to record on graph paper the electrical activity of the heart. The picture is drawn by a computer from information supplied by the electrodes
