What is an Electrophysiology Study?
Electrophysiology (EP) Study: This study involves several tests performed in a special lab in the hospital that can take up to several hours. These tests help pinpoint the location, the type of arrhythmia, and how the arrhythmia responds to treatment. During an EP study, the patient is sedated and small catheters are guided to the heart. The heart’s rhythm is recorded as small amounts of electricity are delivered through the catheter. This internal recording is often compared with an external recording (from electrodes placed on the patient’s chest and back) taken at the same time.
What is a implantable loop monitor?
Implantable Loop Recorder: A device that continuously monitors the heart rhythm for up to 14 months. This small device is placed under the skin during an approximate 20-minute procedure using a local anesthetic. When a symptom is experienced, the patient places a hand-held activator over the recorder. Later, a physician analyzes the stored information.
What is a External Loop Recorder?
External Loop Recorder: A device that monitors heart rhythm and rate for up to one month. During this test, the patient wears a device on the wrist or around the waist. When symptoms are experienced, the patient presses a button on the device to make a recording of the heart activity that just occurred.
What is a Holter Monitor?
Holter Monitor (24-72 hour ECG): A device that measures and records heart rhythm over 1-3 days. This test may be done when an ECG does not show the arrhythmia and it still is suspected to be the cause of symptoms. Patches with wires are placed on the chest. The wires are connected to a portable monitor that can be attached to a purse or belt.
What is a Exercise ECG or Stress Test?
Exercise ECG or Stress Test: A graphical recording of the heart’s rhythm during exertion. The exertion may be created using a treadmill machine or by using medications that mimic exercise. This test helps evaluate whether exercise can create an arrhythmia or make it worse. Or, it can show if there may be not be enough blood flowing to the heart (ischemia).
What is a Electrocardiogram (ECG)?
Electrocardiogram (ECG): A graphical record of the heart”s rhythm and rate for a second. To record the ECG, patches with wires are placed on the chest and the wires are connected to a monitor. This is typically done in a physician”s office or hospital setting. This test helps narrow the search for identifying the specific arrhythmia.
