An electrocardiogram (EKG or ECG) is a test that measures the electrical activity of your heart. We use this test to determine how your heart is functioning. A wave is recorded with each heartbeat, as electrical impulses travel through the heart. This wave causes the muscles to contract (squeeze) and pump blood from the heart.

A Holter monitor is a small device that you wear that tracks the rhythm of your heart for up to 14 days. This allows us to see your heart rhythm as you perform your daily activities.

An event monitor is a portable device used to record your heart’s electrical activity when symptoms are detected. Just like an electrocardiogram (ECG), the electrical heart activity is recorded, but for longer durations of time. Typically the recorded device information is transmitted remotely. This is different from a Holter Monitor that continuously records over a period of time.

An echocardiogram uses sound waves (ultrasound) to create images of the heart. The images show your heart beating and pumping blood. This test is used to detect abnormalities or heart disease.

A pacemaker or defibrillator has the ability to communicate through the skin with a programmer. It is necessary to routinely evaluate the programming of the device and confirm the battery and wires (leads) are functioning appropriately. The interrogation is performed by placing a wand over the chest where the device is located.
