“…[1][2][3][4][5][6] However, the characteristics of AF retrieved from pacemaker interrogation, in particular its duration, may differ from those derived from clinical observations. Recent advancement of pacemaker algorithms for the prevention of atrial tachycardias, fibrillation and flutter (AT/AF) with atrial overdrive pacing (AOP) has been expected to reduce the incidence of AT/AF, though the effectiveness of these preventive algorithms is still controversial.…”

Background: Although atrial high rate episodes (AHRE) have been commonly used to detect atrial tachyarrhythmias (AT/AF) in pacemaker patients, its reliability and characteristics are unclear. Methods and Results:39 patients with implanted dual chamber pacemakers (mean age 79.7±6.6 years), who had no history of AT/AF and were programmed in the setting of AHRE at >190 beats/min in DDD mode, were studied. An atrial overdrive pacing (AOP) algorithm was randomly programmed "ON" in 19 and "OFF" in 20 patients. AHRE were detected in 20 patients (51%), consisting of AT/AF in 15 and repetitive non-reentrant ventriculoatrial synchrony (RNRVAS) in 8 patients, all included in the AOP "ON" group. A total of 257 of 1,528 episodes of AHRE were available for analysis, including 181 and 76 episodes in the AOP "ON" and "OFF" groups, respectively. Among 181 episodes in the AOP "ON" group, 72 (40%) were RNRVAS, whereas all episodes in the AOP "OFF" group (100%) were AT/AF. Detection of RNRVAS was closely associated with a high cumulative % atrial pacing. The specificity of AT/AF detection by AHRE was 40% when the AOP algorithm was activated, vs. 100% when not in use.Conclusions: AT/AF was common in pacemaker patients without a history of AT/AF. The increase in cumulative % atrial pacing and the use of an AOP algorithm might be closely associated with RNRVAS, non-AT/AF, detected by AHRE. (Circ J 2011; 75: 1090 - 1097

“…Capucci et al found that the risk of TE, adjusted for known risk factors, increased by 3.1 times in patients with devicedetected AF episodes longer than 1 day during follow-up. 11 Our data showed that patients with persistent AF were 9.8 times more likely to have TE events during the perioperative period. One reason for the high risk of TE may be that anticoagulation with warfarin was discontinued or even not previously prescribed before the procedure in those patients with a history of AF or previous stroke.…”

Background: Thromboembolism (TE) is one of the most serious complications after pacemaker implantation. It has been demonstrated that several patient characteristics and different pacing modes are related to an increased risk of TE events during long-term follow-up. Hypothesis: We propose that TE events occurring during the perioperative period of pacemaker implantation may be associated with certain clinical characteristics. Methods: The potential risk factors of TE events were analyzed in 406 consecutive patients who underwent pacemaker implantation. Results: We identified TE events in 11 patients (2.7%) within 7 days after pacemaker implantation. Four of the 11 (36.4%) patients died of complications of TE. Univariate analysis revealed that an age of >75 years (4.56 odds ratio [OR], P = 0.031), hypertension (3.59 OR, P = 0.028), diabetes (8.89 OR, P < 0.001), coronary heart disease (4.8 OR, P = 0.005), atrial fibrillation (AF) (5.68 OR, P = 0.006), persistent AF (10.36 OR, P < 0.001), and a history of stroke or transient ischemic attack (5.62 OR, P = 0.002) were associated with an increased risk of TE events. Multivariate logistic analysis showed that persistent AF (9.8 OR, P < 0.001) was independently associated with TE. The incidence of perioperative TE was not significantly different between patients with single-and dual-chamber pacemakers. Conclusions: We found TE events during the perioperative period in patients undergoing pacemaker implantation were not uncommon. Because persistent AF during the perioperative period was the only independent risk factor for perioperative TE, appropriate anticoagulation therapy may be necessary in those patients.

“…23 In contrast, another study looking at the duration of atrial high rate events, found that only episodes lasting longer than one day increased risk. 27 The investigators also noted that 12% of the cohort received an ICD shock during the first 3 months after implantation. Occurrence of a shock was associated with an increase in hospitalization for CHF and for subsequent shocks, but not death.…”
