Connexin45 provides optimal atrioventricular nodal conduction in the adult mouse heart.
RATIONALE The gap junctional protein connexin (Cx) 45 is strongly expressed in the early embryonic myocardium. In the adult hearts of mice and humans, the expression mainly is restricted to the cardiac conduction system. Cx45 plays an essential role for development and function of the embryonic heart because general and cardiomyocyte-directed deficiencies of Cx45 in mice lead to embryonic letha...
متن کاملHeart Rate and Atrioventricular Nodal Conduction Mechanism and Physiological Implications
This study 1) compares the negative chronotropic and dromotropic actions of adenosine in guinea pig, rat, and rabbit hearts; 2) investigates the mechanism(s) for the different responses; and 3) determines the physiological implications. Isolated perfused hearts were instrumented for measurement of atrial rate and atrioventricular (AV) nodal conduction time. Differences in metabolism of adenosin...
متن کاملConnexin45 expression is preferentially associated with the ventricular conduction system in mouse and rat heart.
Cardiac myocytes are electrically coupled by gap junctions, clusters of low-resistance intercellular channels composed of connexins. Variations in the quantities and spatial distribution of different connexin types have been implicated in regional differentiation of electrophysiological properties in the heart. Although independent studies have demonstrated that connexin43 is abundant in workin...
متن کاملReevaluation of enhanced atrioventricular nodal conduction: evidence to suggest a continuum of normal atrioventricular nodal physiology.
The syndrome of enhanced atrioventricular nodal (AVN) conduction has been defined arbitrarily by: AH interval during normal sinus rhythm (AH-NSR) less than or equal to 60 msec; shortest right atrial pacing cycle length (PCL) maintaining 1:1 AVN conduction (shortest PCL 1:1) less than or equal to 300 msec; and at the shortest PCL 1:1, an increase in the AH interval from AH-NSR (delta AH) less th...
متن کاملProcainamide and retrograde atrioventricular nodal conduction in man.
Recent studies that show a depressant effect of procainamide (PA) on retrograde conduction in patients with atrioventricular (AV) nodal reentrant tachycardia (RT) have suggested possible incorporation of AV nodal bypass tracts. Electrophysiologic effects of i.v. PA, 10 mg/kg, on retrograde AV nodal conduction were examined in 13 patients without RT, demonstrable AV nodal refractory period curve...
