• Sinoatrial node reentrant tachycardia (SANRT) is caused by a reentry circuit localised to the SA node, resulting in a P-wave of normal shape and size (morphology) that falls before a regular, narrow QRS complex. (wikipedia.org)
  • Torsade de pointes is an uncommon and distinctive form of polymorphic ventricular tachycardia (VT) characterized by a gradual change in the amplitude and twisting of the QRS complexes around the isoelectric line (see the image below). (medscape.com)
  • This short report investigated a possible connection between COVID-19 and benign paroxysmal positional vertigo (BPPV). (hindawi.com)
  • We present two cases of benign paroxysmal positional vertigo (BPPV), which developed within two weeks of SARS-COVID-19 infection, manifesting with mild disease severity in early November 2020. (hindawi.com)
  • The authors offer a review of the current knowledge about the epidemiology, risk factors, pathophysiology, diagnostics and therapy of the chronic venous insufficiency (CVI). (amedi.sk)
  • Most have a narrow QRS complex, although, occasionally, electrical conduction abnormalities may produce a wide QRS complex that may mimic ventricular tachycardia (VT). (wikipedia.org)
  • Identify the etiology and epidemiology of mitral regurgitation medical conditions and emergencies. (nih.gov)
  • Patients presenting with sustained ventricular tachycardia should be treated according to symptoms and tolerance of the arrhythmia. (amedi.sk)
  • Dr. Anam Tariq from the John Hopkins School of Medicine's department of nephrology discusses epidemiology for hypertension. (drbeen.com)
  • SVT and paroxysmal SVT are triggered by a reentry mechanism. (medscape.com)
  • Tachycardia induced cardiomyopathy is a decline in left ventricular function and left ventricular dilation as a result of chronic or frequently recurring paroxysmal tachycardia. (wikidoc.org)
  • The diagnosis should be suspected if a patient was known to have normal LV function who sustains a decline in the setting of recurrent, paroxysmal or a chronic tachyarrhythmia. (wikidoc.org)
  • Ser96Ala genetic variant of the human histidine-rich calcium-binding protein is a genetic predictor of recurrence after catheter ablation in patients with paroxysmal atrial fibrillation. (cdc.gov)

  • In 1930, Wolff, Parkinson, and White described a series of young patients who experienced paroxysms of tachycardia and had characteristic abnormalities on electrocardiography (ECG). (medscape.com)
  • The objective of this study was to systematically review the efficacy and safety of all different CA strategies for the treatment of patients with paroxysmal (PAF) and non-paroxysmal AF (non-PAF). (biomedcentral.com)
  • Eventually "the periodic syndrome" was parsed into benign paroxysmal torticollis of infancy, benign paroxysmal vertigo of childhood, cyclic vomiting syndrome, and abdominal migraine. (medlink.com)
  • Weiya Zhang has published over 150 peer-reviewed papers in the past 10 years in epidemiology, clinical trials, systematic reviews and evidence based guidelines in OA, gout and other musculoskeletal disorders. (nottingham.ac.uk)
  • There also appear to be abnormalities in calcium handling and calcium channel activity that may explain the reduction in cardiac contractility [6] These abnormalities can persist up to 4 weeks after discontinuation of the tachycardia. (wikidoc.org)
  • The condition can be characterized as either paroxysmal, lasting for less than seven days, or persistent, lasting more than seven days. (medtigo.com)
  • In general, a history of structural heart disease markedly increases the likelihood that the tachycardia is ventricular in origin. (wikipedia.org)
  • Resumption of normal or near normal left ventricular function following resolution of the tachycardia establishes the diagnosis. (wikidoc.org)
