Before recommending a pacemaker, your doctor will consider any arrhythmia symptoms you have, such as dizziness, unexplained fainting, or shortness of breath. He or she also will consider whether you have a history of heart disease, what medicines you're currently taking, and the results of heart tests.
Pacemaker malfunction includes failure to pace, failure to capture, undersensing, and pacemaker-mediated dysrhythmias. Failure to pace occurs when the pacemaker does not fire when pacing should occur. On the ECG, there are no visible pacing spikes where they should have occurred.
