Always show the pacemaker registration card to any doctor or dentist providing treatment. Most pacemaker generators have an X ray code that can be seen on a standard CXR. Some hospital equipment, including equipment used in surgery, may interfere with pacemakers. The pacemaker may need to be protected during any operation and reprogrammed .This mode varies with pacemaker set up and manufacturer. Usually initiates an asynchronous pacing mode AOO, VOO, or DOO. Asynchronous modes deliver constant rate paced stimuli regardless of native rate of rhythm. In asynchronous ventricle pacing there is a risk of pacemaker induced ventricular tachycardia..See also Stroke Like Symptoms Caused by Pacemaker Malfunction. Further Reading. Basic Principles of Pacing by Kirk M. Pacemaker Timing Cycles by Hayes and Levine . A beer inspired mnemonic to remember the NBG pacemaker code from Cana.M can be found here..The pacemaker rhythm can easily be recognized on the ECG. It shows pacemaker spikes vertical signals that represent the electrical activity of the pacemaker. Usually these spikes are more visible in unipolar than in bipolar pacing. In the first example, the atria are being paced, but not the ventricles, resulting in an atrial paced rhythm..
