There were no differences between paced and slow-paced conditions, suggesting that AV synchrony rather than heart rate was primarily contributing to cardiac output. Further studies are needed to understand the chronic impact of JR on Fontan outcomes....
A subsequent 12 lead ECG in the ICU revealed atrial pacing and ventricular sensing (ApVs) (Fig. 1-A) while chest x-ray showed normal lead positions in right arial appendage and right ventricular apex. The sensed and paced AV delay was 170 msec and 200 msec respectively, with a lower ...
The mean of 10 consecutive cardiac cycles was used for patients in AF and three cardiac cycles for patients in paced rhythm. Quality-of-life assessment (Appendix) Patients completed health-related QoL questionnaires at baseline, six months, and 12 months. The following questionnaires were ...
Electroanatomic characterization of conduction barriers in sinus/atrially paced rhythm and association with intra-atrial reentrant tachycardia circuits following congenital heart disease surgery. J Cardiovasc Electrophysiol 2001;12:1725. DelacretazE, GanzLI, SoejimaK, FriedmanPL, WalshEP, TriedmanJK, et ...
Atrial (AERP) and atrioventricular node (AVERP) effective refractory periods were measured using S1/S2 stimulation protocols in which the heart was paced at a cycle length of 100 ms (S1) followed by an extra stimulus (S2) at progressively shorter cycle lengths. Inducibility of AF was ...
no significant differences between the groups in baseline CHA2DS2-VASc scores, duration of paced QRS, positioning of the RV lead, or use of medications. However, patients with significant LAE had a longer follow-up period than did those without significant LAE (8.0±4.6 vs 6.7±4.9 years; P...
The paced percentage of HBP or LBBP was also assessed. A comprehensive assessment was also performed consisting of a medical questionnaire, physical examination, and quality of life assessments. Ventricular functions and remodeling were assessed by echocardiography with an modality of pacing who is ...
Objective To study the effect of the overexpression of sarcoplasmic reticulum Ca2+-ATPase(SERCA2a) mediated by AAV1 on the SERCA2a activity and protein in rapid right atrial-paced rabbit models.Methods Thirty New Zealand rabbits were divided into sham operation group(group A),AAV1/green fluoresc...
Nonetheless, P waves (stars) that continue with unchanged cycle length after mode switch with a different ventriculoatrial interval demonstrate isorhythmic but independent sensed and paced events. A-EGM = atrial electrogram; AMS = automatic mode switch; AP = atrial pacing; AS = atrial sensing; ...
6, the processor 224 identifies ventricular events at block 301, such as R-waves based on Rout signal line 202, and identifies the ventricular event as being either an intrinsic sensed event Vs or a paced event Vp resulting from pacing being delivered by ICD 10 or 10′ (or by ICD 110 ...
