  • Bifascicular block or LBBB in young individuals should prompt screening of siblings and consideration of genetic testing to exclude a genetically determined progressive conduction abnormality (e.g. (escardio.org)
  • 40 bpm) to assess for chronotropic response, with the failure to achieve 85% of maximal age-predicted heart rate suggesting sinus node disease. (escardio.org)
  • Further testing may be indicated to exclude other diagnostic possibilities. (medscape.com)
  • Depending on which disorder you are looking to identify, Holter monitoring, exercise testing and cross-sectional imaging can be invaluable in reaching a diagnosis. (escardio.org)
  • Resting blood pressure +/- ambulatory monitoring, exercise testing, Holter monitoring and echocardiography are recommended. (escardio.org)
  • This drug test should not be performed in patients with a type 1 ECG pattern (see Table above) because it adds no new information. (medscape.com)

  • NCT03352648) is an international, multicenter, and multivendor study to assess the net reclassification improvement (NRI) for the indication of ICD implantation by the use of cardiac magnetic resonance (CMR) as compared to TTE in patients with ICM. (bvsalud.org)
  • Our goal in this study was to assess the efficacy of intravenous dofetilide, in five different dosing regimens, for treating patients with inducible atrioventricular re-entrant tachycardia, by determining its ability to prevent reinduction of the tachycardia. (bmj.com)
  • While you are having an ECG test you will be given an injection of ajmaline or flecainide (antiarrhythmic drugs). (myheart.org.uk)

  • It is likely that your doctor will suggest you have a number of tests before the decision is taken to implant an ICD. (heartrhythmclinic.com)
  • This test allows your doctor to consider your individual risk of developing VT or VF by inducing your arrhythmia in the controlled environment of the catheter lab. (heartrhythmclinic.com)
  • Your doctor can then assess whether or not you would benefit from having an ICD implanted. (heartrhythmclinic.com)
  • In some people VT or VF is not inducible during the test, but your doctor may still advise that you need an ICD. (heartrhythmclinic.com)
