Changes in myocardial threshold. Physiologic and pharmacologic factors in patients with implanted pacemakers
(Elsevier, 1967-08)
Seventy-one controlled threshold studies were performed on 14 patients with implanted cardiac pacemakers.Eating and sleeping raised myocardial threshold significantly, whereas exercise had a reverse effect. A solution of ...
Measurement of pacemaker performance
(Elsevier, 1966-01)
Entirely satisfactory treatment of complete heart block has been prevented by an inability to measure pacemaker function after implantation. Two major problems can be identified in the long-term management of pacemaker ...
Myocardial threshold in patients with artificial pacemakers
(Elsevier, 1966-07)
A method for estimating myocardial threshold in patients with implanted artificial pacemakers has been described. By the external application of a calibrated suppression signal, the output of the implanted unit can be ...
