What is the significance of an ECG showing atrial fibrillation with premature ventricular contractions (PVC) strip in a patient's cardiac evaluation?
The significance of an ECG showing atrial fibrillation with premature ventricular contractions (PVC) in a patient's cardiac evaluation is that it can indicate a potential risk for irregular heart rhythms and possible underlying heart conditions. This combination of findings may require further investigation and monitoring to assess the overall health of the heart and determine appropriate treatment options.
What is more serious atrial or ventricular fibrilation?
Ventricular fibrillation is more serious than atrial fibrillation because it can lead to cardiac arrest and sudden death if not treated immediately. Atrial fibrillation, while still a serious condition, is generally less life-threatening than ventricular fibrillation.
What is the name and function of the thicker layer of cells next to the epidermis?
The thicker layer of cells next to the epidermis is called the dermis. Its main function is to provide structural support to the skin, containing blood vessels, nerves, sweat glands, and hair follicles. It also helps regulate body temperature and supplies nutrients to the skin.
Is the cell membrane of a plant thicker than an animals?
In a plant there is: cell wall cell membrane chloroplast cytoplasm nucleus vacuole Animal: Cell membrane cytoplasm nucleus So yeah
A ventricular wall motion abnormality that is reversible with nitroglycerin is?
likely due to coronary artery vasospasm, which can result in transient ischemia. Nitroglycerin dilates coronary arteries, increasing blood flow to the affected area and relieving the spasm-induced wall motion abnormality. It is important to investigate the underlying cause of vasospasm and address any coronary artery disease risk factors.
What is the significance differences in thickness of ventricular wall?
the right ventricle contains deoxegynated blood, but the left ventricle pumps oxygenated blood out at a much more forceful rate (it has to get to the rest of you body). Therefore, the left ventricle wall is thicker. =]
What is eccentric left ventricular hypertrophy?
Ventricular hypertrophy means a thickening of the ventricle walls. This can then be described as eccentric or concentric. Eccentric hypertrophy is where the wall thickens but the ventricle itself dilates therefore the wall is thickened but the ventricular chamber remains the same size. Concentric hypertrophy is where the wall thickens which then makes the internal ventricular chamber smaller.
Why are auricular walls thicker than the ventricular walls?
you are mistaken...the ventricular walls are thicker than the auricular walls.. The left ventricle is further thicker than the right ventricle. This is because the left ventricle has to transport blood to all the parts of the body and has to travel a long distance hence requires it to be transported at great pressure. As a result the wall is thicker. The auricles only have to pump blood into the ventricles underneath them and therefore don't require alot of pressure hence are not thick. The right ventricle however pumps the deoxygenated blood into the lungs and has to travel a relatively short distance since the lungs are close to the heart hence not alot of pressure is required either. All this explains why the Ventricular walls are generally thicker than the auricular walls.
What is the significance of the difference in thickness between the wall of the aorta and the wall of the pulmonary trunk?
I answered this question last week... but anyway... the aorta has to accommodate much higher pressures from the left ventricle, ergo it is thicker.
How does the structure of a frog's ventricular wall compare to it's atrial wall?
The short Answer: The ventricles have thicker walls than the atrium simply because this is the part of the heart that does most of the pumping action by contracting. It has to be strong and fairly thick to cope with the pressure. (Ventricles have thicker walls than the atrium, which creates a higher blood pressure. The left ventricle has thicker walls because it needs to pump blood to the whole body. The wall of the left ventricle is 8-15 mm The right atrium's wall is approximately 2mm in thickness, due to the combined influence of the low pressure of this chamber and the ease of pumping to low pressure areas)
Why the wall of the ventricle is thicker?
cause it is !! :)
Why is the left ventricular wall more muscular than the right ventricular wall and why is it necessary?
because it is pumping against more resistance. it has to be stronger to get blood to the entire body. the RIGHT ventricle only has to pump blood to the lungs.
Is arteries wall thicker or veins?
artries
Which wave is larger the one for atrial contraction or the one for ventricular contraction?
The wave for ventricular contraction is larger than the wave for atrial contraction. This is because the ventricles have thicker muscle walls and contract more forcefully in order to pump blood out to the body.
What factors can increase myocardial oxygen demand?
Heart rate and ventricular wall tension
Is Artery more thicker than vein?
the wall of an artery is usuallythicker that the wall of a vein.
What is the ventricular septum?
That portion of the heart wall that divides the right and left ventricles
