Atrioventricular Junctional Rhythm

Rhythm Nodal


Presentation

  • Presents a new chapter on recording and interpreting heart rhythms in patients with pacemakers. Includes new material on interpreting ECG findings associated with implantable cardioverter-defibrillators.[books.google.com]
  • P waves may be present or absent. P waves may not be related to the QRS complexes. P waves may be located before, during or after the QRS complex (due to retrograde conduction). Usually, some degree of atrioventricular (AV) block accompanies.[metealpaslan.com]
  • Many a medical registrar will be grateful for this clear, concise, up-to-date manual Lancet This book presents a concise and simplified approach to the diagnosis and management of abnormalities in cardiac rhythmOne of the books strengths is the number[books.google.com]

Irregular Heart Rhythm
  • Racial disparities seen in U.S. heart rhythm treatment (Reuters Health) - Black patients in the U.S. with atrial fibrillation - an irregular heart rhythm - are less likely to receive the medications that would help prevent stroke, the most dangerous outco[bioportfolio.com]

Suggestibility
  • Intravenous verapamil (10 mg) induced no change in the junctional pacemaker rate and postpacing pauses suggesting that the slow inward current did not play an important role in the nonparoxysmal junctional rhythm.[ncbi.nlm.nih.gov]
  • The data suggest that AV junctional rhythms in group I were caused by normal automaticity, while those in group II were probably due to abnormal automaticity.[ncbi.nlm.nih.gov]
  • This suggests that, under catecholamine stimulation, adenosine may have different mechanisms of action on AV nodal conduction and automaticity.[ncbi.nlm.nih.gov]
  • Whereas the occurrence of atrioventricular junctional activity during radiofrequency ablation does not necessarily herald a successful ablation of slow atrioventricular node pathway conduction, its absence strongly suggests that the energy is being applied[ncbi.nlm.nih.gov]
  • The increased voltage in this ECG suggests left ventricular hypertrophy. Click here for a more detailed ECG ECG 2. The ECG above belongs to a 51 years-old woman.[metealpaslan.com]

Workup

  • In the last two years, I seem to be in a junctional rhythm constantly, sometimes with sinus rhythm as well….Seen several MDs and had a fairly comprehensive workup in last several years including normal echo, CMRI, and Holter/Event studies showed nothing[texasheart.org]
Suppression
  • AV junctional rhythms in group II (five patients) were not suppressed by overdrive pacing. In contrast, the rate increased after overdrive pacing.[ncbi.nlm.nih.gov]
  • In six patients, adenosine suppressed the junctional rhythm without producing AV nodal block. In the other 11 patients, the junctional rhythm was terminated prior to the occurrence of AV nodal block.[ncbi.nlm.nih.gov]
  • A junctional rhythm is protective — the AV node serves as a backup for the SA node — so it should not be suppressed.[emtresource.com]
Wide QRS Complex
  • The rate is faster, and the QRS complexes narrow, both conditions causing a better cardiac output than wide QRS complexes and extremely slow rates.[ecgguru.com]
