Atrioventricular Junctional Rhythm in School Cardiac Screening

Atrioventricular junctional rhythm: classification and clinical significance.

Accelerated junctional rhythm, isorhythmic atrioventricular dissociation, and hidden P waves.

62-year-old diabetic, hypertensive woman with prior stenting of her dominant right coronary artery underwent coronary arteriography because of an abnormal stress test. A 90% narrowing of the left circumfl ex coronary artery beyond the second obtuse marginal branch was stented with a 3 × 18-mm drug-eluting stent. She went to the recovery room in good condition, and an electrocardiogram was recor...

Differences in the determinants of overdrive suppression between sinus rhythm and slow atrioventricular junctional rhythm.

Sinus node recovery time was compared to the recovery time of a slow atrioventricular junctional rhythm in each of the same seven pentobarbital anesthetized dogs. Recovery time and the first five cardiac cycles were examined after pacing atria and ventricles for 20, 40, and 60 seconds at four or more pacing cycle lengths. Data relating recovery times and return to control conditions to prepacin...

The controllability of cardiac rhythm in elderly

Introduction: Recent reports have shown that rare fluctuations in cardiac cycles are ‘forgotten’ quickly in healthy individuals and it is possible to quantify the “memory length” of a physiological time-series using an inverse statistical approach. Methods: In the present study, we assessed the effect of aging on memory length in cardiac rhythm. Results: There was a long...

Site of origin and molecular substrate of atrioventricular junctional rhythm in the rabbit heart.

During failure of the sinoatrial node, the heart can be driven by an atrioventricular (AV) junctional pacemaker. The position of the leading pacemaker site during AV junctional rhythm is debated. In this study, we present evidence from high-resolution fluorescent imaging of electrical activity in rabbit isolated atrioventricular node (AVN) preparations that, in the majority of cases (11 out of ...
