heart disrupts the normal coordination of heart muscles. These muscles lose their vital rhythm and begin a process known as ventricular fibrillation. Death soon follows. 0.25 Amps/250mA is equal to the current flowing through a 60W Bulb. What is ventricular fibrillation? The heart beats when electrical signals move through it. Ventricular fibrillation is a condition in which the heart’s electrical activity becomes disordered. When this happens‚ the heart’s lower (pumping) chambers contract

The three different waveforms are a representation of the electrical activity of the heart. The P wave represents the depolarization of the atrial valve. The QRS complex represents the depolarization of the ventricular valve. Also‚ the T wave represents the repolarization of the ventricular valve. The change in amplitude represents the different heartbeat patterns such as normal‚ fast‚ slow

In this week’s we got to take a look at an article called Learning to Move by Karen E. Adolph. In this article she talks about the discovering of moving for babies. She states that infants must cope with variable and novel conquering gravity infants must cope with variable and novel constraints on balance and propulsion. Before reading this article I wanted to know about how infants are able to cope with the ability to move and learn about flexibility and specificity. In her article she wanted to

ii of the PALS provider manual is very helpful. This site has a pretest and other helpful tools. This document contains information on the PALS 2010 Guidelines. Basic Dysrhythmias knowledge is required in relation to asystole‚ ventricular fibrillation‚ tachycardias in general and bradycardias in general. You do not need to know the ins and outs of each and every one. Tachycardias need to differentiate wide complex (ventricular tachycardia) and narrow complex (supraventricular tachycardia or

blood back down to the ventricles but the aortic semi lunar valve is has shut itself so blood may not backwash back into the ventricles. During this time‚ blood will be slowly returning back into the left atrium by ventricular diastole second phase & atrial systole but do note that the atrioventricular valves are still closed so blood doesn ’t wash into the ventriculars. Blood will travel through arteries then to arterioles and lastly to capillaries so it may begin a gas exchange of oxygenated blood

1. What do those numbers (130/87) mean? What do they relate to in the cardiac cycle? The numbers 130/87 is the blood pressure of the patient. The top number 130‚ is the reading that is received when the heart is in contraction and blood is pushed out of the heart into the rest of the body (this is called systole). The bottom number 87‚ is the reading when the heart is at it relaxed state and is being refilled with blood (this is called diastole.) 2. This deposition of platelets and fibrin can
