These studies record the changes of electrical potential occurring during the heartbeat, used especially in diagnosing abnormalities of heart action. EKG studies include Pediatric EKG, Signal-Averaged EKG, Routine Treadmill EKG and Holter Monitor Studies.
These studies that take "moving pictures" of the heart with sound waves. A more recent development uses electromechanical or electronic techniques to scan the ultrasound beam rapidly across the heart to produce two-dimensional images of selected sections of the heart. The types of echo studies include:
Pulsed Wave, Continuous Wave and Color Flow Doppler
Transesophageal Echo: Biplane and Multiplane
Exercise Stress Echo
Dobutamine Stress Echo (Pharmacological Stress Echo) GDL
