There are three main types of pacemakers. Single chamber pacing is a method where one lead is inserted into the atrium or the ventricle. Dual chamber pacing is a method where two pacing leads go into the heart. One goes into the right atrium while the other goes into the right Ventricle.

Stress echocardiogram: This is an echocardiogram that is performed while the person exercises on a treadmill or stationary bicycle.

The echocardiogram is performed just prior and just after the exercise.
