Pacing technology: advances in pacing threshold management

Pacing failure caused by automatic pacing threshold adjustment system

Ventricular capture management is an automatic pacing threshold adjustment algorithm that automatically measures pacing threshold through detection of the evoked response after a pacing stimulus. Although it is principally designed to save device battery under the maintenance of the patient׳s safety, we experienced a rare case with serious pacing failure due to a weakness of this algorithm. Thi...

Clinical advances in diaphragm pacing.

Diaphragmatic pacing is a valuable tool that can significantly benefit certain patients with respiratory insufficiency provided they have an intact phrenic nerve and a functional diaphragm. Careful patient selection is critical to successful long-term results. The main populations that derive benefit from pacing include those with congenital or acquired central hypoventilation syndrome and more...

Recent Advances in Pacing and Defibrillation

Most current pacemaker and ICD systems involve placement of lead(s) transvenously into the heart, connected to a pulse generator. Vascular access may be difficult or limited in some patients, and intravascular leads can be associated with multiple complications such as infection, lead malfunction and vascular occlusion. Recent advances in pacing and ICDs include the development of subcutaneous ...

Circadian pattern of atrial pacing threshold in the young.

AIM The aim of this study was to evaluate the circadian variation of atrial pacing threshold in young patients. METHODS AND RESULTS Atrial Capture Management (ACM) algorithm is a Medtronic EnPulse pacemaker (PM) feature that uses two algorithms: atrioventricular conduction (AVC) (atrial pacing and spontaneous AVC) and atrial chamber reset (ACR) [intrinsic atrial activity with atrioventricular...
