30-Day Event Monitoring in Reseda, CA

How event recorders differ from Holter monitors

Ambulatory monitoring looks for transient cardiac problems that are not apparent on a standard EKG — especially intermittent arrhythmias and, in some Holter analyses, silent ischemia.

A Holter records a continuous tracing for 24 or 48 hours. Recovered event-monitor education described a looping recorder that stores a short recent segment of rhythm — about 30 seconds in that older description. When you have the symptom, you press a button to freeze that recording.

How long it can be used

A major advantage described in recovered education is that event recorders can be used for 30 to 60 days, until the transient symptom occurs. If the symptom typically lasts more than a minute or two, electrodes may not need to stay on all the time; they can be attached when needed because applying them takes less than a minute.

Your specific device and wearing instructions come from the office. Newer monitors may work differently than the tape-based systems described on the older site.

What information can be gained

Event monitors are useful for correlating a patient’s heart rhythm with symptoms. If symptoms are caused by a transient arrhythmia, an event recorder is often a practical way to capture it.

A Holter shows every beat during a short continuous window and can be harder to match to sporadic symptoms. Recovered text also noted that event recorders are not useful for diagnosing silent ischemia, because those episodes have no symptom to trigger a transmission.

When event monitoring may be chosen

A Holter often fails to provide a diagnosis if the condition occurs less often than every day or every other day. Continuous 24- to 48-hour recording may miss an arrhythmia that occurs about once a month.

Your physician chooses the monitor based on how often symptoms occur and what question needs to be answered.

Older telephone transmission

The recovered 30-day event page described transmitting a frozen recording by telephone to an interpreting center. That trans-telephonic workflow is an older method and may not match how current monitors send data.

Ask the office how your assigned monitor should be returned or uploaded. Do not assume a phone-line transmission is still used.

When to contact the office

Call Cardiac Rhythm Specialists if you were asked to wear an event monitor or have infrequent palpitations or fainting that have not been captured on a Holter. Call 911 for emergency symptoms.
