Studies of Short — and Long-Term Threshold Changes

  • Chapter

Abstract

The measurement of diastolic stimulation threshold at pacemaker implantation is a necessary prerequisite for the verification of an optimally longterm functioning of implanted pulse generator systems (34). Thereby, the initially measured threshold energy can be primarily seen as an expression of optimal electrode positioning and a technically flawless system of impulse transmission by the pacemaker electrode. Measurements dealing with improved pacemaker electrode technology presuppose a homogeneous group of patients. A uniform basis for the evaluation of later developing pacemaker stimulatory threshold can only be obtained if physiological, patho-physiological and pharmacological conditions are kept constant. On a short-term basis, conditions can be kept constant, usually without difficulty, in order to observe the influences of the individual factors. Long-term continuous observations must on principle be able to differentiate between a summation of factors at implantation and later measurements.
