Holter Monitor & Loop Recorder

Holter Monitor

A Holter monitor, worn on a belt or in your pocket, has electrode patches that are placed on the patient’s chest, recording each heartbeat and heart rhythm continuously for a full 24-hour cycle.

A diary is provided so the patient can take note of any symptoms they experience (such as palpitations, skipped beats, chest discomfort or shortness of breath). This way, the physician knows precisely when to focus on the heart rhythm of the patient.

When the 24-hour period is complete, the patient removes the electrode patches and puts the monitor in a safe place until it is brought to the doctor’s office for analysis. Remember, once the electrode patches are disconnected, the Holter monitor stops recording. The Holter monitor must remain dry. You may bathe, shower, or swim once the monitor has been removed.

Since the Holter monitor can record over 100,000 heartbeats in a day, it may take 24-48 hours to process your recording. Your physician will call you with a report.

Event Monitor

An Event monitor is a small device, similar to a Holter monitor. It is used to evaluate a patient over a longer period of time (usually one to four weeks).

The Event monitor only records a patient’s heartbeats when a button is pushed. It is specially programmed to record several seconds of time before the button is pushed, and several seconds afterwards. Most monitors allow patients to push the button several times before the data needs to be transmitted over the phone to the doctor’s office. The Event monitor also requires several electrodes to be applied to the skin.

Event monitors and their electrodes can be removed and replaced at any time. Remember not to get the Event monitor wet. You may remove the Event monitor to bathe, shower, sleep, or swim. Your doctor may provide additional instructions for use.

When you pick up your Event monitor, the technician will show you how to transmit readings back to the practice. If you forget, call the office and the technician will review the steps with you again. You may call any day between 9 am and 12 noon, and 1 pm and 4 pm.

Loop Recorders

A paper clip-size device called an implantable loop recorder (ILR) that evaluates the heart’s rhythm can be implanted during a simple office visit with minimal risk.  The device communicates to doctors and nurses via wireless Bluetooth from a monitor in the home and has a battery that lasts approximately three years.  The ILR is approved for implantation in patients who have episodes of loss of consciousness or prior transient ischemic attack/stroke when no clear cause has been identified. 

The ILR can help identify dangerous heart rhythms that can lead to recurrent strokes (e.g., atrial fibrillation) or recurrent blackouts due to slow or fast abnormal heart rhythms.  The ILR is approved for implantation at the Mount Sinai Doctors Manhasset office.
