The 3-year rate of inappropriate ICD therapy atrial flutter/fibrillation was 8% in the single-chamber versus 3% in the dual-chamber patients (P = 0.006) (Figure 1) with adjusted dual: single hazard ratio of 0.47, p=0.03. There was no difference in appropriate shocks or mortality between ...
atrial flutter (Figure 1) with variable AV conduction, multifocal atrial tachycardia (Figure 2), and wandering atrial pacemaker. Conversely, a regular pulse or rhythm does not exclude AF. For example, AF can manifest with a regular ventricular response in the presence of AV block or with a ...
without heart disease, the fibrillatory process may begin as atrial flutter or may be precipitated by one or more atrial premature complexes (Figures 15-14 to 15-16). In a number of patients with paroxysmal supraventricular tachycardia, atrial fibrillation evolves during an attack of tachycardia....
(as defined by ≥30 seconds of AF or flutter detected by device or a new clinical diagnosis recorded in claims data) at the end of the 4-month monitoring period in the immediate monitoring group compared with the delayed monitoring group, in both the intent-to-treat and per-protocol ...
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. ...
Given the common association with AF, atrial flutter events were included in the primary and secondary AF outcomes. The outcomes were identified through 2 methods. First, participants self-reported new diagnoses of AF on annual follow-up questionnaires. Second, the VITAL population was linked to ...
Digoxin is used to treatatrial fibrillation, atrial flutter, and heart failure. My cardiologist told me that many of the younger cardiologists don’t generally even prescribe it any longer. Digoxin has a narrow therapeutic index, which means that at too low of a dose it isn’t very effective...
OBJECTIVES This study investigated the extent of fractionation of paced right atrial electrograms in patients with and without paroxysmal atrial flutter (AFL) or atrial fibrillation (AF). BACKGROUND Slow conduction through nonuniform anisotropic atrial muscles, represented by fractionated electrograms, may ...
FIGS. 1A and 1B are flowcharts illustrating methods of detecting atrial tachyarrhythmia in accordance with embodiments of the invention; FIGS. 2-3 are timing diagrams illustrating undersensing of atrial events; FIG. 4 illustrates atrial flutter with 3:1 ventricular pacing and atrial undersensing; ...
