Printout of pacemaker telemetry data shows the cardiac and paced events since the last evaluation. This pacemakeer is programmed to pace and sense the ventricle in a patient with chronic atrial fibrillation. Only 2 of the heartbeats that the patient actually had were caused by the pacemaker. The remaining 98 were intrinsic beats. This strip would be representative of a patient with atrial fibrillation and poor rate control suggesting that an increase in AV node blocking drugs such as digitalis or an AV node ablation would be appropriate. makes the electrical connection automatic and does not rely on the physician to make a secure connection with a screw. Leads Pacemaker leads are more than simple wires. They are complex and highly engineered devices and consist of many components Fig. . Figure shows some of the many different types of leads that have evolved in an effort to reduce the size and increase the reliability of this critical pacing component. Each part of the lead is highly specialized and will be .
