Getting to the Heart of the Matter

Intermittent heart palpitations feel like your heart is racing, pounding, skipping, jumping or beating very slowly with pauses. These palpitations can be frightening, making it important to find out the cause so you can feel better and prevent serious problems.

Electrophysiology focuses on your heart’s electrical activity to locate the source of the abnormal heartbeat (arrhythmia). Electrical signals usually travel through the heart in a regular pattern. Heart attacks, aging and high blood pressure may cause the heart to beat in an uneven pattern. Extra abnormal electrical pathways found in certain congenital heart defects can also cause arrhythmias.

Based on your symptoms, we will match you with the best monitor to check your heart rhythm. We specialize in external and implanted monitors, and offer remote monitoring options if applicable.

Monitoring and specialized tests will help determine whether medicine or a surgical procedure is best for you.
