  • conduction
  • Often, the flutter waves are not completely transferred through the AV node to the ventricular heart chambers so occasionally electrical conduction blocks occur and produce a 2:1, 3:1 or 4:1 ventricular contraction rate that is mainly regular. (medicinenet.com)
  • The most common atrial flutter occurs when the atria beat at a rate of 300 bpm and ventricular contraction rate is 150 bpm (2:1 conduction). (medicinenet.com)
  • In contrast to flutter waves, the abnormal conduction creates irregular, rapid occurring QRS waves, some of which are conducted to the heart ventricles through the AV node. (medicinenet.com)
  • Macroreentry atrial flutters took varied pathways, but each had an area of slow conduction (ASC) averaging 16 ± 6 mm (range 6-29) in length. (springer.com)
  • OBJECTIVE: The difference of the conduction velocity (CV) around the tricuspid valve annulus between the counter-clockwise (CCW) atrial flutter and the clockwise (CW) atrial flutter has not been well clarified. (biomedsearch.com)
  • New antiarrhythmic drug strategies include more atrial selective agents, drugs similar to amiodarone but with a less toxic profile, or drugs with novel mechanisms of action, such as gap junction facilitation of conduction. (oncologynurseadvisor.com)
  • coronary
  • Atrial flutter occurs most often in people with heart diseases such as pericarditis, coronary artery disease and cardiomyopathy. (heart.org)
  • If a person with atrial flutter also has coronary artery disease , the rapid heart rate can place enough stress on the cardiac muscle to cause angina . (verywellhealth.com)
  • Clinical
  • See 'Overview of atrial flutter', section on 'Clinical manifestations' and 'Embolic risk and the role of anticoagulation in atrial flutter', section on 'Embolic risk' . (uptodate.com)
  • 12 patients who had atrial flutter without clinical, echocardiographic or angiographic evidence of aortic insufficiency were studied with simultaneous echo- and phonocardiograms. (ahajournals.org)
  • A clinical electrocardiographic study was performed on 41 patients with atrial flutter. (journals.co.za)
  • Boston, MA -- ( SBWIRE ) -- 03/26/2013 -- GlobalData's clinical trial report, "Atrial Flutter Global Clinical Trials Review, H1, 2013" provides data on the Atrial Flutter clinical trial scenario. (sbwire.com)
  • This report provides elemental information and data relating to the clinical trials on Atrial Flutter. (sbwire.com)
  • The databook offers a preliminary coverage of disease clinical trials by their phase, trial status, prominence of the sponsors and also provides briefing pertaining to the number of trials for the key drugs for treating Atrial Flutter. (sbwire.com)
  • cardiac
  • Many of these atrial flutters occur in patients who have undergone previous medical procedures such as valvular or congenital cardiac surgery involving atriotomy, surgical Maze operations, or pulmonary vein isolation procedures. (springer.com)
