  • nodal
  • We hypothesized that as an alternative, implantation of autologous fibroblasts in the perinodal region would focally modify AV nodal conduction and that this modulation would be enhanced by pretreatment with transforming growth factor-β1 (TGF-β1), a stimulant of fibroblasts. (ahajournals.org)
  • abnormal
  • Your veterinarian will also take X-rays of both the thoracic and abdominal regions to see if there are any abnormal masses, tumor, foreign body, and/or abnormal heart position. (petmd.com)
  • murine
  • Recent papers have attributed arrhythmic substrate in murine RyR2-P2328S hearts to reduced action potential (AP) conduction velocities (CV), reflecting acute functional inhibition and/or reduced expression of sodium channels. (surrey.ac.uk)
  • impulses
  • 1:48 Skip to 1 minute and 48 seconds These cells are able to generate and conduct electrical impulses, which in turn stimulate the heart muscle to contract. (futurelearn.com)
  • Specialized myocytes in the heart that conduct the electrical impulses throughout the heart. (thefreedictionary.com)
  • excitation
  • The differences should have important implications in the use of the mouse heart to study excitation, propagation, and arrhythmias. (ahajournals.org)
  • 1-6 However, the ionic mechanism underlying excitation of the heart in any species is dependent on the specific set of ion channel proteins expressed in the particular type of heart tissue, and an adequate use of a genetically altered heart requires, as an important first step, a sufficient understanding of its basic cardiac electrophysiology.

  • fibers
  • The first paper , with Colleen Mitchell was a simple cardiac model, similar in spirit and complexity to the FitzHugh-Nagumo model, but based on the heart rather than nerve fibers. (duke.edu)
  • Anterior
  • Vectorcardiographic study of aberrant conduction anterior displacement of QRS: another form of intraventricular block. (bmj.com)
  • In the other 5 instances, aberrant conduction manifested itself by a conspicuous anterior displacement of the QRS loop, with increased duration of anterior forces. (bmj.com)
  • Severe
  • Severe conduction disorders in patients presenting granulomatosis with polyangiitis are rare but can contribute to increased morbidity. (figshare.com)
  • Methods
  • Methods On a 12-lead ECG, available for 37 antiretroviral therapy (ART) naïve, 42 ART-exposed vertically-acquired HIV-infected and 50 healthy children in Jakarta, Indonesia, we measured cardiac conduction parameters: PR, QRS, and QTc (corrected using Bazett's formula) intervals. (bmj.com)
  • pump
  • The role of the heart is to pump blood around the body, enabling oxygen, nutrients and waste products to be transported to and from the different cells and organs. (futurelearn.com)
  • Our heart is a powerful pump that performs its duty around the clock. (lecturio.com)
  • acute
  • Endomyocarditis, or inflammation of the inner heart muscle and lining, is an acute heart and lung (cardiopulmonary) disease that typically develops. (petmd.com)
  • Skip
  • 0:10 Skip to 0 minutes and 10 seconds The heart lies in the space between the lungs, which is called the mediastinum. (futurelearn.com)
  • Does heart blockage cause your heart to skip beats? (reference.com)
  • A second-degree heart block may cause the heart to skip a beat or beats, explains the National Heart, Lung and Blood Institute. (reference.com)
  • Often most people will sometimes feel their heart skip a beat, or give an occasional extra strong beat - neither of which are usually a cause for alarm. (medhelp.org)
  • studies
  • An unusual patient is described in whom electrophysiological studies strongly suggest the occurrence of Mahaim conduction. (bmj.com)
  • involvement
  • This helps in the diagnosis of underlying heart disease or problem, and the extent of heart involvement. (petmd.com)
  • 1 Cardiac involvement may have diverse manifestations from initial asymptomatic presentation to overt heart failure to sudden death. (bmj.com)
  • block
  • This case reports on a young female patient, previously diagnosed with granulomatosis with polyangiitis, who was admitted to the intensive care unit with seizures and hemodynamic instability due to a complete atrioventricular heart block. (figshare.com)
  • lung
  • Normally, heart murmurs do not require treatment unless they are caused by another condition, states the National Heart, Lung, and Blood Institute. (reference.com)
  • Common and rare SCN5A coding variants were examined for association with PR and QRS intervals through meta-analysis of European ancestry participants from CHARGE, National Heart, Lung, and Blood Institute's Exome Sequencing Project (n=607), and the UK10K (n=1275) and by examining Exome Sequencing Project African ancestry participants (n=972).
