- Electrocardiogram (ECG) —shows the electrical activity of the heart rhythm and rate.
- Ambulatory or holter monitoring —continuous cardiac monitoring. This may be used if you have symptoms but heart rhythm disturbance does not show up on an ECG. This type of monitoring is helpful because it measures heart activity over a longer period of time.
- Echocardiogram —shows an image and function of heart structures using ultrasound (high-frequency sound waves).
