Pacing-Overdrive Dog
The functional integrity of the (3and a-adrenergic stimulatory pathways in a rapid ventricular pacing model of congestive heart failure in dogs was investigated; normal dogs served as controls. Total (-adrenergic receptor density was 35% lower (p<O.O1) in the pacing-overdrive dogs, and the (-adrenergic receptor-mediated stimulation of adenylate cyclase (Vm.) was found to be 68% and 72% lower (p...
متن کاملself-adapting autodecremental overdrive pacing
The efficacy and safety of a new antitachycardia pacing technique, self-adapting decremental overdrive pacing, was assessed in patients with clinical ventricular tachyarrhythmias who underwent programmed ventricular stimulation and serial drug testing. The three phases of this study involved a learning/experience phase, followed by intrapatient comparison of decremental overdrive pacing with co...
متن کاملOverdrive atrial pacing does not improve obstructive sleep apnoea syndrome.
The aim of this study was to assess the ability of overdrive atrial pacing to reduce sleep apnoea severity. A total of 17 unselected patients (12 males; mean+/-SD age 71+/-10 yrs; body mass index 27+/-3 kg x m(-2)) who had received permanent atrial-synchronous ventricular pacemakers for symptomatic bradyarrhythmias and not known to have central or obstructive sleep apnoea syndrome (OSAS) were s...
متن کاملThe relationship between overdrive suppression and overdrive excitation in ventricular pacemakers in dogs.
We studied the excitatory and inhibitory effects of overdrive on idioventricular pacemakers in anesthetized dogs with recently induced complete atrioventricular block. The following results were obtained: (1) a slow driving rate may induce a temporary rhythm which may be reinstituted with additional stimuli; (2) the induced rhythm may appear as coupled extrasystoles which, on interruption of th...
متن کاملEffective prevention of atrial fibrillation by continuous atrial overdrive pacing after coronary artery bypass surgery.
OBJECTIVES The present study was aimed to evaluate the efficacy of a specific algorithm with continuous atrial dynamic overdrive pacing to prevent atrial fibrillation (AF) after coronary artery bypass graft (CABG) surgery. BACKGROUND Atrial fibrillation occurs in 30% to 40% of patients after cardiac surgery with a peak incidence on the second day. It still represents a challenge for postopera...
