Diagnostic Tests for Arrhythmia

Our heart rhythm specialists have the tools and experience to carefully and correctly diagnose all forms of irregular heart rhythm. We may ask you to wear a heart monitor that you can take with you to home and work.

  • Electrocardiogram (EKG)

    This test records the electrical activity of your heart. An EKG provides information about your heart's rate and rhythm. It also diagnoses ischemia (lack of oxygen to the heart muscle), heart attacks, and a variety of other heart conditions.

  • Stress Testing

    This test, also called a treadmill or exercise test, involves stressing the heart and monitoring the heart's reaction. A stress test helps evaluate the heart's capacity for work. The test can use exercise, medication, or both to induce stress.

  • Holter Monitor

    This device records the electrical activity of your heart as you go about your daily activities. You will wear the Holter monitor for 24 to 48 hours.

  • Ambulatory Telemetry and Event Monitors

    These devices are similar to a Holter monitor. They record your electrical activity for up to 30 days. They have a button you can push to indicate when you are experiencing heart symptoms.

  • Electrophysiology Study

    During this procedure, a heart rhythm doctor delivers small electrical impulses to the heart to help evaluate your heart rhythm. Your doctor will do this in the catheterization "cath" lab at the hospital.

  • Genetic Testing

    If arrhythmia runs in your family, it is important to tell your doctor. There are several irregular heart beat syndromes that have genetic factors, including Long QT syndrome and sudden cardiac arrest. A genetic counselor can help you and your family members explore genetic testing and treatment options.

More About Tests for Arrhythmia

electroencephalography EEG


An electrocardiogram is a procedure that records the electrical activity of the heart.


Ambulatory Telemetry Monitors

Ambulatory EKG monitoring allows your healthcare providers to monitor your EKG over a period of time, while you're going about regular activities.


Heart Function Stress Tests

Heart function stress tests provide measurable feedback about the function of the heart.

An electrophysiology (EP) study helps your doctor diagnose and evaluate abnormal heart rates and rhythms.


Genetic Testing

Genetic testing is a blood test that looks for errors, or mutations, in your DNA and genes.
