Single-lead VDDR pacing incorporating a mode-switching option is useful in patients with high degree AV block and paroxysmal atrial fibrillation, since it provides atrial synchronous ventricular pacing in more than two-thirds of follow-up time. In a subgroup of patients, a progressive increase of...

The prevalence of atrial flutter is less than one-tenth of the prevalence of AF. Atrial flutter often coexists with or precedes AF. Left or right atrial macro re-entrant tachycardia is mainly found in patients after catheter ablation for AF, AF surgery, or after open-heart surgery. 6. ...

(TEAP)was per-formed on 54 patients with SSS whose atrioventricular conduction was normal inelectrocardiogram before pacing.The incidence of LAVB was 96% in patients withSSS.The second-degree type one LAVB frequently occurred in the patients who hadhad first-degree LAVB,and the second-degree ...
AF is postulated to have two autonomic subtypes: vagally-predominant, in younger patients, with onset typically at night when vagal tone is higher, and adrenergically-predominant, in older patients, with episodes more common during daytime when sympathetic tone is at its circadian peak...
Of these circuits, 30 represented common cavo-tricuspid isthmus (CTI)-dependent flutter, with 29 cases counter-clockwise and 1 clockwise. These CTI-dependent flutters were distributed as follows: 7 in complex CHD (4 of 7 TGA and 3 of 8 Fontan), 17 in moderate CHD (7 of 10 TOF, 2 ...
However, we must emphasize that the non-steroidal anti-inflammatory drugs (NSAIDs) were shown to increase, in a large population-based case-control study, the elevation of the relative risk of AF or atrial flutter (AFlu) [36]. Recent intensive studies revealed the role of miRNA in AF-...
