What else can I help you with?
Will the apical beat be shifted in left ventricular hypertrophy?
Yes, in left ventricular hypertrophy, the apical beat may be shifted laterally and inferiorly due to the increase in left ventricular mass and displacement of the apex by the hypertrophied myocardium.
What does myocardium receive it's blood supply directly from?
The myocardium receives blood from the coronary arteries.
If the blood supply to the myocardium stops what happens?
that part of the heart tissue dies
What is deficient blood supply to the myocardium called?
Deficient blood supply to the myocardium is called ischemia. This lack of blood flow can result in decreased oxygen and nutrients reaching the heart muscle, leading to potential damage if left untreated.
What are the pathways through the body for electrical impulses?
in what order do the structures of the neuron carry the electrical signal?
During systole the ventricular myocardium gets its oxygen supply mainly from?
myoglobin
Life threatening dysrythmia that causes the ventricular myocardium to quiver in an uncoordinated and ineffective way?
Ventricular fibrillation, or V-Fib.
What are the arteries that supply the myocardium?
The coronary arteries
What network is found in the ventricular myocardium?
The network found in the ventricular myocardium is known as the Purkinje fibers. These specialized cardiac muscle fibers are part of the heart's conduction system and are responsible for rapidly transmitting electrical impulses throughout the ventricles. This helps coordinate the contraction of the ventricles, ensuring efficient pumping of blood. The Purkinje fibers facilitate a synchronized contraction, allowing for effective ventricular function.
Will the apical beat be shifted in left ventricular hypertrophy?
Yes, in left ventricular hypertrophy, the apical beat may be shifted laterally and inferiorly due to the increase in left ventricular mass and displacement of the apex by the hypertrophied myocardium.
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
Where does the myocardium receive its blood supply?
the coronary arteries
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)
These Arteries supply the myocardium?
Coronary artery
Where does the Myocardium receive all of its blood supply?
coronary arteries
What does myocardium receive it's blood supply directly from?
The myocardium receives blood from the coronary arteries.
