Electrocautery-induced pacemaker malfunction during surgery.
We report a case of electrocautery-induced pacemaker failure that resulted in asystole in a 15-year-old girl scheduled for cardiac surgery. Her pacemaker was converted to the asynchronous mode the night before surgery. Electromagnetic interference from the unipolar electrocautery caused a reduction in the battery voltage, which allowed the digital circuitry, but not the voltage control oscillat...
متن کاملTriboelectric simulation of pacemaker malfunction.
We report the occurrence of a triboelectric phenomenon (static electricity) that mimicked malfunction of a contemporary pacemaker by creating an electrocardiograpic artifact virtually identical to the pacemaker stimuli. The diagnosis was established by observing a subtle overshoot of the questionable deflection that was absent from pacemaker stimuli.
متن کاملMuscle potentials simulating pacemaker malfunction.
Interference spikes were noted on the electrocardiogram of a patient with an implanted demand pacemaker. Runaway malfunction was suspected and the generator replaced. Subsequent investigation showec that the interference originated from fasciculation in the left leg caused by underlying neuromuscular disease. Skeletal muscle potentials can produce an electrocardiographic appearance closely rese...
متن کاملElectrocautery-induced airway fire during tracheostomy.
Although most of the recent attention regarding airway fires has focused on the intraoperative use of the laser, it is important to remember that electrocautery may also serve as a source of ignition during surgery involving the airway and/or oropharyngeal cavity. This subject is mentioned in only a handful of isolated reports in the recent literature (1-3). The following is, we believe, the fi...
