Introduction The major function of the heart is to force blood in to a closed system of blood vessels within which the blood is confines and circulated to the entire body. Heart’s activity can be compared to a muscular pump equipped with one way valves. With each heartbeat‚ an electrical impulse travels through the heart and causes the heart muscle to squeeze and pump blood from the heart. These electrical impulses‚ transmitted through the heart‚ are spread throughout the body. This electrical

left arm; as well as‚ in the right and left ankles. Finally‚ the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate. Introduction An electrocardiogram can be used to record activity during the cardiac process of pumping and returning blood to the body and heart because of the electric current that spreads through the tissue of the heart and to the surface of the body. By using four electrodes‚ one on your left and right wrist and one on the upper

Summary: AED Defibrillators: Having access to an AED is essential for resuscitating those who have suffered from SCA (sudden cardiac arrest). Because the incidences of SCA are increased during and after strenuous physical activity‚ every school should have AED(s) that can be accessed very quickly. Sudden Cardiac Arrest: Sudden cardiac arrest is the leading cause of death in young athletes. NATA convened an inter-association task force in Atlanta in 2006 to create guidelines on emergency management

DE LA SALLE UNIVERSITY DASMARINAS Dasmarinas City‚ Cavite OBSERVING THE ELECTRICAL ACTIVITY OF THE HEART USING ELECTROCARDIOGRAM Villar‚ Samantha Belle B. Ylade‚ Kristianne Joy G. Perillo‚ Jeanne 18 March 2014 ABSTRACT In this activity‚ the electrical activity of the heart was examined using the Electrocardiogram (ECG/EKG). Proper handling was performed by removing the metals present in the body and by cleaning the surfaces of the skin‚ to avoid the disruption of signal of the machine. Assessment

Muscles are all made of the same materials‚ a type of flexile tissue of thousands narrow tissues that make up all the muscles. There are three types of muscle tissue in the human body which are Cardiac‚ Smooth and Skeletal Muscles. Cardiac Muscles are muscles that conduct‚ forced‚ being completely in heart‚ responsible for pumping activity of heart‚ very heavy and solid. Smooth are non band‚ not under voluntary force found in comfortable organs of body accountable for growth like absorption of food

Comparing the Cardiac muscle and the Skeletal muscle Differences Similarities Skeletal muscle is usually linked to bones by structures called tendons. Cardiac muscle is found in the heart. They are both important parts to the body. Skeletal muscle cells are usually arranged into cylindrical fibres with multiple nuclei and can be directly controlled by voluntary nerve signals from the nervous system. Cardiac muscle cells are normally shorter and are linked via gap junctions which allow compounds

disease is the number one killer in the United States of America. Sudden cardiac death‚ or SCD‚ is the largest cause of natural death in the United Sates. SCD causes about three hundred twenty-five thousand adult deaths each year in the US. Half of all heart disease deaths are caused by sudden cardiac arrest. Occurring mainly in adults in their mid-thirties to mid-forties‚ SCD affects only one or two children each year. Sudden cardiac arrest is not a heart attack‚ or myocardial infarction‚ but it is possible
