Subcellular distribution of prostaglandin-E2 and prostaglandin-F(2α) in atrial tissue from patients with mitral valve disease
(1998)
The distribution of prostaglandin-E2 (PGE2) and prostaglandin-F(2α) (PGF(2α)) was studied in subcellular fractions isolated from homogenates of human atrial fresh tissue by differential centrifugation. Right and left atrial ...
The effect of harmaline on force of contraction of the rat isolated atrium
(1975)
In rat isolated right atria, beating spontaneously at 30°C, harmaline 8.3 × 10-5 M slowed atrial rate and enhanced force of contraction. The velocity of development of tension (dT/dt) increased and time to peak tension was ...
Determination of the vectorelectrogram in isolated rat atria: application to the study of arrhythmias

Differential regulation of atrial contraction by P1 and P2 purinoceptors in normotensive and spontaneously hypertensive rats
(Nature Publishing Group, 2014-03-01)
In the normotensive rat atrium, adenosine-5'-triphosphate and uridine-5'-triphosphate exert a biphasic effect consisting of an initial negative inotropic effect (NIE) followed by a subsequent positive inotropic effect ...
Atrial Coronary Arteries in Areas Involved in Atrial Fibrillation Catheter Ablation
(LIPPINCOTT WILLIAMS & WILKINS, 2010)
Background-The proximity to vascular structures is a limiting factor during radiofrequency ablation. However, little or no attention has been given to the atrial arterial circulation during the development of atrial ...
Long-term nitric oxide inhibition and chronotropic responses in rat isolated right atria
(1999-10-01)
The long-term administration of nitric oxide synthesis inhibitors induces arterial hypertension accompanied by left ventricular hypertrophy and myocardial ischemic lesions. Because the enhancement of sympathetic drive has ...
