While you go about your daily activities, the cardiac monitor keeps track
of your heart's electrical activity. Recordings are stored based on your
doctor's programmed settings. Your doctor can use these recordings and
information from you about your symptoms to help monitor, diagnose,
and manage heart rhythm disturbances (called arrhythmias), or to
determine if your symptoms are related to something else. Your
symptoms may include syncope (fainting), light-headedness, dizziness,
and palpitations (sensations of an unduly rapid or irregular heartbeat).
The cardiac monitor records an electrocardiogram (ECG), which is a
pattern of your heart's electrical activity. Your doctor can review the
stored ECG, which helps to show if your heart's rhythm is too slow, too
fast, irregular, or normal.
There are two ways the cardiac monitor stores this ECG information for
your doctor to review later:
• ECG recordings stored when you or a caregiver uses the Patient
Assistant.
• Automatic ECG recordings based on how your doctor has
programmed the cardiac monitor. Your doctor can tell you how many
recordings your cardiac monitor is programmed to store.
