Abstract: . . .  rhythm is restored by blocking the flutter circuit (see pp. 116117). Fig. 3 AF suppression pacemaker. This device paces the atria slightly faster than the sinus rate, preventing bradycardia and atrial ectopy that otherwise trigger atrial fibrillation . 940ftxt06 14/7/04 11:23 am Page 107  . . .

. . .  intracardiac electrograms from right atrium, (RA) during successful ablation of atrial flutter. Rapid, regular atrial depolarisation is seen to proceed around the right atrium until sinus rhythm is restored by blocking the flutter circuit (see pp. 116117). Fig. 3 AF suppression pacemaker. This device paces the atria slightly faster than the sinus rate, preventing bradycardia and atrial ectopy that otherwise trigger atrial fibrillation .  . . .
. . .  between the tricuspid annulus and the inferior vena cava. This strip of tissue can be targeted for radiofrequency ablation, a potentially curative treatment for this arrhythmia Atrial fibrillation and flutter epidemiology and mechanisms Atrial fibrillation is caused by multiple, interlacing re-entry circuits involving predominantly the left atrium. Risk factors include age, hypertension, mitral . . .
