Life threatening dysrythmia that causes the ventricular myocardium to quiver in an uncoordinated and ineffective way?
Ventricular fibrillation, or V-Fib.
What nerves supply the ventricular myocardium?
Sympathetic nerves from the cardiopulmonary division T2-T5
During systole the ventricular myocardium gets its oxygen supply mainly from?
myoglobin
Network of conducting tissue located in the ventricular myocardium?
The cardiac conduction tissues in the human heart comprise specialized myocytes that can be differentiated from working myocardium with routine histological staining. They are located in specific regions of the heart to form the sinus node and the atrioventricular (AV) node, which then extend into the AV bundle and bundle branches
What can decrease the cardiac output?
The cardiac output can be decreased by decreasing the force of contraction of the ventricular myocardium and decreasing the heart rate.
What has the author Jan Kugelberg written?
Jan Kugelberg has written: 'Ventricular defibrillation' -- subject(s): Arrhythmia, Electrotherapeutics, Myocardium
What chamber of the heart has the thickest myocardium?
The Left Ventricle has the thickest walls! The left ventricular myocardium is much thicker then the right ventricular myocardium because the left ventricle pumps blood into the aorta which takes blood to the rest of the body. (larger pressure gradient)
How do you use the word myocardium in a sentence?
Myocardium is muscular tissue that is found in the heart. Myocardium is an essential element in the workings of the heart.
Network that stimulates the myocardium into contraction?
His bundle? or the Purkinje fibers?
What are the five areas of specialized myocardium?
sinoatrial node, right and left bundle branches, atrioventricular node, atrioventricular bundle, ventricular walls.
What are the pathways through the body for electrical impulses?
in what order do the structures of the neuron carry the electrical signal?
Where on the cardiac cycle does a synchronized shock land?
A synchronized cardioversion shock is delivered a few milliseconds after the R wave on the EKG. The R wave represents ventricular depolarization, which is followed by mechanical contraction of the ventricle. Therefore, it can be seen that a synchronized shock will occur during ventricular contraction, or during ventricular systole, to completely depolarize the myocardium and try to restore a normal rhythm.
