  • reentrant
  • Frame et al 17 demonstrated that DWR was responsible for pacing-induced acceleration of reentrant tachycardia around the tricuspid annulus in a canine atrial preparation. (ahajournals.org)
  • congestive heart f
  • The ANDROMEDA study, was terminated prematurely after enrolment of 627 of 1,000 planned patients with congestive heart failure, in relation to excess mortality due to worsening heart failure in the dronedarone group [n=25 vs. 12 (placebo), p=0. (cardiacrhythmnews.com)
  • Background- Increased plasma levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) have been identified as predictors of cardiac dysfunction and prognosis in congestive heart failure and ischemic heart disease. (ahajournals.org)
  • anticoagulation
  • In the general patient population, those with a CHA 2 DS 2 -VASc risk score of ≥ 2 are thought to be at a moderate-high risk for stroke and will likely benefit from oral anticoagulation. (davita.com)
  • characteristics
  • The study indicated that, after accounting for differences in baseline characteristics, there were no apparent differences in outcomes between patients who were and were not prescribed oral anticoagulants. (davita.com)
  • diagnosis
  • Because the specificity of identifying left atrial appendage thrombi is very high for harmonic transthoracic echocardiography, transesophageal echocardiographic examinations may be omitted in patients with the transthoracic diagnosis of thrombi. (kup.at)
  • Sometimes we need only atrial mapping for precise diagnosis. (hvt-journal.com)
  • waves
  • In AFL, atrial F waves usually occur at a rate within 220-350 bpm, although the rate may decrease below 200 bpm or increase to 400 bpm. (hvt-journal.com)
  • Atrial flutter waves may be present in the jugular venous pulse. (patient.info)
  • Eighty-two consecutive patients with type I AFL, identified by negative flutter waves in the inferior leads and positive flutter waves in lead V 1 , 4 who underwent RFA of the RA isthmus by an anatomical approach were included. (ahajournals.org)
  • thrombus
  • One additional thrombus was diagnosed in a patient with a negative transthoracic echocardiographic study. (kup.at)
  • echocardiography
  • More recent studies have demonstrated that harmonic echocardiography may allow transthoracic detection of left atrial thrombi and assessment of left atrial appendage function. (kup.at)
  • Harmonic transthoracic echocardiography allowed imaging of the left atrial appendage and recording of its velocities in 83 % and 74 % of cases, respectively. (kup.at)
  • Modern echocardiographic systems with harmonic transthoracic echocardiography allow the identification of large left atrial appendage thrombi with a high degree of confidence. (kup.at)
  • Transthoracic echocardiography (TTE) is the preferred initial imaging modality for evaluating atrial flutter. (medscape.com)
  • Coronary
  • Coronary artery disease was the most common structural heart disease among patients in groups 1 (n=14), 2 (n=3), and 3 (n=2) and was considered an exclusion criterion for patients in group 4. (ahajournals.org)
  • Six patients had previously undergone coronary bypass surgery (1 in group 1, 2 in group 2, and 3 in group 3), whereas repair of an atrial septal defect (group 1) and Ebstein's anomaly (group 4) was performed in 1 patient each. (ahajournals.org)
  • The isthmus of tissue responsible for atrial flutter is seen anterior to the coronary sinus (CS) orifice. (medscape.com)
  • prevention
  • Anticoagulant therapy with warfarin, dabigatran, rivaroxaban, apixaban, and edoxaban is effective for prevention of thromboembolic stroke in most patients with AF. (centerwatch.com)
  • The investigators' goal is to create and evaluate an alert-based CDS strategy for stroke prevention in patients with nonvalvular AF or atrial flutter in a randomized controlled trial. (centerwatch.com)
  • Relevance- Failure to prescribe anticoagulant therapy for stroke prevention in AF represents a critical patient safety concern. (centerwatch.com)
  • Electrical therapies such as single- and dual-site atrial pacing are being evaluated for the long-term prevention of atrial fibrillation (AF). (onlinejacc.org)
