The Effect of Lead Performance on Myocardial Capture
{"Image DocumentName": "The Effect of Lead Performance on Myocardial Capture", "Image ImageDescription": "What would you expect to happen if a lead was partially fractured? Impedance (or Resistance) would rise. Current would decrease and battery energy conserved. - but - Could you guarantee that enough current (I) can flow through this fractured lead so that each time the pacemaker fired the myocardium would beat? Student Notes. Are all high impedance conditions a good thing? It might be better said that not all high impedance conditions are a bad thing. However, unless you are using a specially designed high-impedance lead, you have to suspect a problem in the circuit when you see a high impedance condition. This problem may have serious clinical consequences (e.g., result in loss of capture).
