Proppranolol incereased pacing threshold
WebSep 1, 2014 · The pacing threshold of all implanted ventricular leads was under 1.0 V. After reaching a satisfactory measurement, the leads were implanted in the optimal position, and then the pacemaker generators were placed in the subpectoral area. All patients were reevaluated 30 days later after implantation. Ethical considerations WebApr 4, 2024 · At 53 years of age, when the patient was hospitalized for a caesarean section, we performed another pacemaker check-up and found that the pacing threshold had increased. Therefore, we implanted a second pacemaker (EnPulse E2DR31; Medtronic) via the left axillary vein.
