A clear association between one or more hyperkalemia excursions and all-cause mortality was observed regardless of the hyperkalemia threshold,” the researchers concluded. WebMany factors affect the threshold for myocardial stimulation in patients with cardiac pacemakers. The acute local tissue reaction at the electrode-myocardium interface accounts for early threshold rises and may be minimized by choice of specific electrodes (steroid-eluting or carbon-tip).
