WebJul 1, 2015 · Failure to sense - "undersensing" This is a situation where the pacemaker, instructed to inhibit itself whenever a viable P or QRS comes along, instead paces irresponsibly, ignoring normal cardiac activity. This pacemaker is in essence asynchronous. The solution to this problem is to reduce the sensor threshold until something happens. WebReduced pacemaker output / output failure may be seen on ECG monitoring if the patient contracts their rectus or pectoral muscles (due to oversensing of muscle activity) usually due to settings on the pacemaker ⇒ increase absolute value of sensitivity (making it …
