atrioventricular node การใช้

• When this happens, the heart's atrioventricular node takes over as the pacemaker.
• In the atrioventricular node, the resting potential is abbreviated, which facilitates conduction.
• But the atrioventricular node can't always hold down the atrial cacophony.
• Digoxin also has important parasympathetic effects, particularly on the atrioventricular node.
• The monograph revealed the existence of the atrioventricular node and the function of Purkinje cells.
• The signal then travels to the atrioventricular node.
• The atrioventricular node position differs from other fowl.
• Together they discovered and described the atrioventricular node " ( AV node, Aschoff-Tawara node " ).
• When hyperstimulated, the left vagal branch predisposes the heart to conduction block at the atrioventricular node.
• The solution is theoretically simple : Boost the atrioventricular node's blocking power and slow down the ventricles.
• :: : Digoxin blocks the atrioventricular node and causes bradycardia & mdash; i . e . negatively chronotropic.
• The calcium blocking activity of AH-1058 can decrease ventricular contractility, heart rate, and conductance through the atrioventricular node.
• The compound works, through a complicated mechanism, by boosting the atrioventricular node's damping action and thus slowing the ventricular rate.
• The electrical pulses then must pass through an area known as the atrioventricular node, the electrical gatekeeper to the ventricles.
• After the development of the SAN, the superior endocardial cushions begin to form a pacemaker as known as the atrioventricular node.
• Pacemaker cells develop in the primitive atrium and the sinus venosus to form the sinoatrial node and the atrioventricular node respectively.
• Wenckebach is credited for describing the median bundle of the heart's conductive system that connects the sinoatrial node to the atrioventricular node.
• The membranous portion, which is close to the atrioventricular node, is most commonly affected in adults and older children in the United States.
• These T-type calcium channels are also found in pacemaker cells, the sinoatrial node ( SAN ) and the atrioventricular node ( AV ).
• Luckily, the atrioventricular node is a responsible gatekeeper; it doesn't respond to every erratic atrial discharge, or the ventricles would quiver into life-ending impotence.
