    Werner Irnich
    Department of Legal Medicine, University Hospital, Giessen, Germany
    Europace 7:353-65. 2005
    ..This paper tries to summarise which effects can interfere with PM, what can be hazardous, and how treatment of PM in MRI can be modified to guarantee compatibility...
  2. ncbi request reprint Georges Weiss' fundamental law of electrostimulation is 100 years old
    Werner Irnich
    Department of Legal Medicine, Project Pacemaker Investigation, University Hospital Giessen, Germany
    Pacing Clin Electrophysiol 25:245-8. 2002
    ..It can be concluded that if there are statements in the literature contradicting one of the above three Weiss theorems, one can infer that the investigation is questionable...
  3. ncbi request reprint Electronic security systems and active implantable medical devices
    Werner Irnich
    Department of Legal Medicine, University Hospital, Giessen, Germany
    Pacing Clin Electrophysiol 25:1235-58. 2002
    ..The same is true if the ventricular sensitivity is routinely set at 7 mV. Pacemaker manufacturers should consider filter improvement with modern technology, but gate manufacturers should not claim the privilege of being out of bounds...
  4. ncbi request reprint How to program pulse duration or tilt in implantable cardioverter defibrillators
    Werner Irnich
    Department of Legal Medicine, University Hospital, Frankfurter Str 58, 35392 Giessen, Germany
    Pacing Clin Electrophysiol 26:453-6. 2003
    ..Programmable shock pulse duration and tilt are useful in optimizing defibrillation, but it is suggested that this can best be accomplished by programming these parameters with the guidance of theory as described in this discussion...

    Europace 9:711-6. 2007
    ..However, today's tilts are too large as judged by theories, which means that high delivered energies can be worse than lower ones. The delivered energy is, therefore, not a meaningful parameter in judging ICDs...
