Cardiac muscle

malfunction in the body that often weakens the skeletal muscles and prevents function in the body. The disease was discovered in 1861 by a French neurologist named Guillaume Benjamin Amand Duchenne, but the discovery of the cause was founded in 1886 ("Diseases - DMD”). One particular muscular dystrophy that affects children is called Duchenne Muscular Dystrophy (DMD) in which a small percentage of boys are born with. DMD is a muscular disease that causes muscles to weaken, inability to function…

this was used because maximal tests can be harmful to participants. Muscular endurance can be described as the ability of a muscle or muscle groups to do continual muscular contractions with resistance, when the muscle can no longer work at a given rate that is fatigue. Muscles that fatigue quickly have low endurance, muscles that take time to fatigue can be categorised as muscles with high endurance. Work can be defined as any activity involving effort to…

general fluctuations in the force values as well as the consistent patterns of the ECG which occurs in regular intervals. 2. This delay is primarily caused by the atrioventricular node (A-V node) and the adjacent conductive fibres. Conduction in cardiac muscle is hindered by the decreasing number of gap junctions along the pathway of conduction which creates a resistance against the conduction of excitatory ions, i.e. Ca2+, from one fibre to another. This ensures that the atria completely…

What are consequences of having a low cardiac output? How will other body systems be affected? Having a low cardiac output decreases the amount of blood pumped out of the heart. This will affect other parts of the body because they won’t be reseving as much blood as they are suppost…

The Effect of Compression Garments on Muscle Endurance in Trained Individuals. In recent years there has been a development of public acceptance that compression garments have a relationship with muscle performance in athletes. This can be seen through the marketing of compression garments, from companies such as Nike and Adidas, as well as being seen on professional athletes. Muscular endurance can be defined as the muscle’s ability to maintain a contraction or to continue repetitive…

Cardiac Arrhythmia is an anomaly in the Heart which can be diagnosed with the help of Electrocardiogram (ECG) signal. ECG signal is a diagrammatic representation of the cardiac signal, which is most important biomedical signal, taken for the feature extraction. Since it is very difficult to analyse the ECG signal due to the size, noise and changes in the signal, automatic system for ECG signal processing is essential. For this, ECG signal is processed using wavelets based signal processing,…

which include weight loss, fitness, strengthening muscles and enhancing immune system. It reduces the risk of many diseases including heart diseases, obesity or diabetes. It also maintains mental health and boosts the confidence too. Types of Exercises Considering their reactions and the effects on a person, exercises are divided into two main categories: • Aerobic Exercises…

injured person on the spot. This disease, known as sudden cardiac arrest (SCA) • What is the sudden cardiac arrest? Cardiac arrest happens when the muscle of the heart suddenly stops beating due to its malfunctioning. The heart has an internal electrical conducting system that controls the rhythm of the heartbeat; Problems in this system can cause abnormal heart rhythms called arrhythmias. That makes the heart stop beating.…

Bones of the skeleton  Muscles  Cartilage  Tendons  Ligaments  Joints  Connective tissue binding to the body’s organs If you break the system down into its separate parts you can gain a deeper understanding of how they create a joint working system within the body. For example, the Skeletal…

, generally, the symptoms of DMD appear between the age of 1 and 6. Since the age of one, the patient gradually began to have difficulties in standing and walking. The weakness of them legs and pelvic muscles will lead to waddling gait and difficult to move. And the bilateral gastrocnemius muscle will gradually tend to hypertrophy, the tendon reflex…
