Holter Monitoring in San Antonio, TX

Continuous heart rhythm monitoring that records your heart’s activity throughout your normal daily routine to help identify irregular heart rhythms.

Understanding Holter Monitoring

A Holter monitor is a small, portable device that continuously records your heart’s electrical activity over 24 to 48 hours or longer, depending on your physician’s recommendation. Unlike a standard EKG that captures only a brief snapshot, Holter monitoring allows your cardiologist to evaluate your heart rhythm throughout your everyday activities.

At Cardiovascular Associates of San Antonio, Holter monitoring helps detect intermittent arrhythmias and other heart rhythm abnormalities that may not appear during an office visit.

What Can Holter Monitoring Detect?

Irregular Heart Rhythms

Detects abnormal heartbeats (arrhythmias) that may occur throughout the day or night.

Heart Rate Patterns

Monitors how fast or slow your heart beats during daily activities and while resting.

Symptom Correlation

Helps determine whether symptoms such as dizziness, palpitations, or fainting are related to changes in heart rhythm.

Treatment Evaluation

Assesses how well medications or previous treatments are controlling abnormal heart rhythms.

When Might Holter Monitoring Be Recommended?

What to Expect

Before Monitoring

A technician will place several small electrodes on your chest and connect them to a lightweight portable monitor. You'll receive instructions on wearing and caring for the device.

During Monitoring

Continue your normal daily routine while the monitor records your heart's electrical activity. You may be asked to keep a diary of symptoms or activities that occur during the test.

After Monitoring

The monitor is returned to our office, where your cardiologist reviews the recorded data and discusses the findings with you along with any recommended next steps.
