    Notes: Radiofrequency (RF) catheter ablation of the atrioventricular node (AVN) and implantation of a ventricular pacemaker can improve cardiac performance in patients with congestive heart failure (CHF) and uncontrolled atrial fibrillation (AF). Alternatively. RF catheter modification of the A VN has been proposed to slow ventricular response during AF without requirement for permanent pacing. Among 44 consecutive patients (mean age 69.7 ± 10.2 years) with drug resistant chronic AF, 22 (group I) had AVN ablation with permanent ventricular pacemaker implantation, while 22 patients had attempted AVN modification. Complete AV block was obtained in all group I patients while only seven (32 %) A VN modification patients (group II) had permanent slowing of ventricular rate. Among patients in group I, mean left ventricular ejection fraction (EF) increased from 32.2%± 8.8% before ablation to 41.9%± 14.6% 4-weeks postablation (P 〈 0.01); exercise tolerance time (ETT) increased from 2.9 ± 2.2 minutes to 4.5 ± 2.9 minutes (P 〈 0.01); and quality-of-life score decreased from 66.1 ± 22.6 to 36.9 ± 17.1 (P 〈 0.01). By comparison, there was only a small increase in ETT in the seven successful group II patients (2.4 ± 1.8 minutes to 3.0 ± 1.9 minutes; P 〈 0.05) and there was no significant change in EF or quality-of-life. While AVN ablation can occasionally have transient adverse effects, it is more effective than AVN modification for improving cardiac performance in selected patients with CHF and AF.

    Notes: Abstract Glucagon-like polypeptide 1 (GLP-1) may be amajor enterogastrone, slowing gastric emptying whenreleased by intestinal nutrients. In six conscious dogs,we studied the effects of GLP-1, on antropyloric motility, gastric emptying, and transpyloricflow after instillation of 500 ml of saline into thestomach. The meal was given and recordings were started15 min after intravenous bolus and infusion of either saline or three different doses of GLP-1.Intravenous GLP-1 produced a dose-related retardation ofgastric emptying associated with a decrease in thenumber and volume of flow pulses in comparison tosaline. This change in transpyloric flow was associatedwith an inhibition of antropyloric pressure waves, astimulation of isolated pyloric pressure waves, and anincrease in basal pyloric tone induced by intravenous GLP-1 infusion. Our findings show that GLP-1has a potent dose-dependent inhibitory effect ontranspyloric flow and gastric emptying. This effect istemporally associated with inhibition of antral“pumping” and stimulation of pyloric“braking” mechanisms.
