In some cases, these arrhythmias are found when the doctor listens to your chest with a stethoscope. However, other tests are usually required (especially if the arrhythmia comes and goes).

Resting EKG - records the heart's electrical activity while you are at rest.

Exercise EKG Stress Test - records the heart's electrical activity while you exercise.

24 Hour Holter EKG - a small portable tape recorder monitors your heart's electrical activity over a 24 hour period while you continue your routine activities. If changes in your heart rhythm occur they will show up during the recording.

Telephone Monitoring - a portable recorder is carried for several days/weeks. Your EKG can be sent over the telephone when you feel symptoms related to your arrhythmia (palpitations, dizziness, etc.)

How Will My Doctor Treat Me?

If the cause of the arrhythmia is known, it is important to first treat the cause. Treatment may involve one or more of the following:

Medications to try to change the arrhythmia to the normal sinus rhythm

Electrical cardioversion

Anticoagulants (blood thinners like coumadin) will usually be needed to prevent blood clot formation
