Cardiac cycle

Supraventricular Tachycardia, Adult Supraventricular tachycardia (SVT) is a kind of abnormal heartbeat. It makes the heart beat very fast and then beat at a normal speed. A normal heart beats 60 to 100 times a minute. This condition can make your heart beat more than 150 times a minute. Episodes of a fast heartbeat can be scary but they are usually not dangerous. They can lead to problems if: They happen often. They last a long time. Symptoms of this condition include: A…

how to administer the possibly life saving measure. All high schools should require a cpr course to be taking in order to graduate because Cpr saves lives, most cardiac arrest situations occur at home, and so they should be able to tell the difference between cardiac arrest and a heart attack. About 900 americans die everyday due to cardiac arrest According to the new york times. when you know how to perform Cpr you might be saving a relative's life, loved ones, or even a stranger. One of the…

Muscle cells play a very important role in movement of our body. There are three types of muscle cells in vertebrates: skeletal, cardiac and smooth. We are mainly going to be concerned with skeletal muscle for this particular experiment. The skeletal muscle is responsible for the voluntary movement of whole body or body parts, manipulation of external objects, support for our skeleton (Sherwood, 2010, p257). Skeletal muscles have a striated structures of alternating light and dark bands…

muscular protein called dystrophin. Dystrophin is a skeletal muscle protein. This protein is known for keeping the muscle cells intact. With the defect in the protein, it causes rapid muscular deterioration. This protein is also found in the cardiac muscles and the brain. The dystrophin gene is located on chromosome X on the short arm. It contains more than 3685 amino acids. While it only accounts for a little of the proteins, its effects are very important. Duchenne and Becker the cells…

Exercise effects the human body in many fascinating ways; as it causes the body to adapt and alter to aid the body’s stimulation. Take when carrying out the Harvard step test practical. This test is where a person carries out a period of exercise for a certain length of time and then records their heart rate before and for so long after the period. This shows how fit and healthy the heart is by showing how long it takes for the heart to go back to a regular resting pulse rate. “The…

Duchenne’s muscular dystrophy Duchenne’s Muscular Dystrophy Zachary Uecker Genetic Disease Abstract Duchenne’s muscular dystrophy is a genetic disease that targets skeletal muscles and over time, the muscles lose protein and are replaced by fats and connective tissue, making the skeletal muscles unusable. In this paper, the parts of Duchenne’s that will be covered are the method of transmission, statistics about Duchenne’s in the population, the pathophysiology, the body systems…

harm to the patient. The nurse made a poor decision when she did not give the medication as ordered, and when she failed to report a continual increase in the patient’s heart rate, and when she failed to ensure documentation of the items such as the cardiac monitor when the patient was transferred to the telemetry unit. All of the negligence resulted in the demise of the patient. The intensive care unit nurse also stated in the case that she was not experienced enough to be working in the unit,…

All heartbeats consist of a mechanical component and an electrical component. The heartbeat is created by cardiac depolarization caused by electrical currents that induce muscle contraction. The electrical component of the heartbeat begins in the Sinoatrial (SA) Node and its function is to send electrical impulses that stimulate your heart to beat, and these impulses induce the atria to contract. As the atria contract, the impulse moves on to the Atrioventricular (AV) node which leads the…

Passive Forces in Limb Movements: Help or Hindrance Introduction Most animals are enabled to move because of contractions and relations of muscles. Vertebrates and invertebrates movement is initiated by a combination of both passive and active forces (Linke, Granzier and Kellermayer, 2003). Passive forces in muscles are forces that develop when an inactive muscle is stretched from its resting length in resistance of the induced stretch. Passive force in the limbs movement of both vertebrate and…

Skeletal System The skeletal system is made up of 206 bones. It also includes cartilage, ligaments and tendons. The two main parts of the skeletal system are the axial skeleton with 80 bones and the appendicular skeleton with 126 bones. The primary purpose of the skeletal system is to provide the body with support, protection, movement, storage for minerals and lipids, and to produce red blood cells. The axial skeleton includes the skull, thoracic cage and vertebral column. The…
