WebNov 29, 2024 · Generally the pacemaker is implanted in a sterile laboratory or operating room by a specialist (cardiologist, surgeon, or cardiac electrophysiologist) with experience in this procedure. Local anesthesia and often conscious sedation are used to make the procedure as pain-free as possible. General anesthesia is rarely required. WebNov 8, 2024 · Failure to Pace If the pacemaker does not generate an electrical impulse when needed, failure to pace occurs. In this tracing the pacemaker spikes are missing. Failure to Sense When the pacemaker does not detect cardiac depolarization, failure to sense occurs. This can often be seen on an ECG tracing as a spike following a QRS complex too early.
