Cardiac pacemaker

external defibrillator is a shock that is delivered to the heart. It is made to be used in life threatening situations such as arrhythmia or cardiac arrest. To use an automated external defibrillator you must first have one. Then you proceed to prepare for an AED (Automated External Defibrillator)you check to make sure that the patient is indeed having a cardiac arrest, then use the ABC method •Airway: You need to make sure the airway is open before you check his breathing. To do this, tilt…

The heart muscle is called the Myocardium. The Myocardium is the middle and thickest layer of the heart wall. The muscle functions by providing a type of “scaffolding” for the heart chambers and when contracting it pumps blood out of the heart and then relaxes as the heart refills with returning blood. The Myocardium’s smooth outer membrane is called the epicardium and its inner lining is called the endocardium. The heart muscle like any other organ or tissue in your body needs oxygen-rich…

Hypertrophy means that the muscles size will increase. Hypertrophy happens when the amount contractile proteins (Actin & Myosin) increase inside the muscle cells so the way in which the can contract is far greater.the amount of fibres in the muscles remain the same mount. Statistically males have a greater chance in muscle bulk due to higher levels of the hormone testosterone. As it relates to skeletal muscle, hyperplasia defines muscle growth due to an increase in the quantity of muscle…

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.…

This rectangular shaped cell is the Cardiac Muscle cell. Each cell is relatively small, and has one nucleus (sometimes 2) They are connected by microscopic features of the cardiac muscle. This is known as the intercalated discs. These intercalated discs contain cell structures called desmosomes and gap junctions. Compared to skeletal muscle cells, these cells are Y shaped and are a lot shorter and wider. Desmosomes are thick patches in the cell membrane region, usually lying between two…

I. Introduction A. CPR is an emergency procedure that is performed when a person’s heart has stopped beating due to sudden cardiac arrest. Cardiopulmonary resuscitation uses chest compressions and breathing to try to mimic and restore your heart’s natural rhythm. B. Introduction to Four Main Topics 1. First, I will discuss a brief history of CPR. 2. Second, I will discuss the steps to perform CPR. 3. Third, I will share some statistics on CPR. 4. And fourth, I will discuss on where…

Maximum contractile force production dependant on muscle and sarcomere length in isolated sartorius muscle of Rhinella marina Abstract: An isolated Sartorius muscle of Rhinella marina was repeatability stimulated with electrical impulses to induce isometric contraction. Contractile forces evoked were measured with a force transducer and the relationship between force and muscle length was investigated through the modulation of sample lengths from 80%-140% of the sample resting length. The data…

Specific Purpose: To demonstrate and inform the audience how to properly conduct CPR on an infant. Thesis: I would like to make this occasion a subject of much interest in saving a life, it’s about learning to conduct CPR on an infant correctly. Introduction: Conducting CPR is an important technique. Performing simple procedures and following some specific guidelines, you may save lives if a basic treatment is administered until professional medical help arrives. Attention grabber – As a…

Introduction Patient outcomes should be the ultimate goal of any health care interaction. Unfortunately, reality and outside forces make perfect patient outcomes hard to achieve. Safe staffing practices are one such outside force that alter patient outcomes. The current nursing shortage complicates staffing patterns as higher levels of patients are requiring health care. This research article does a good job at establishing reasonable, and attainable staffing pattern guidelines. Nursing is one…

Occurring mostly in males, Duchenne Muscular Dystrophy is an X-linked disorder that includes progressive muscle weakening caused by an insufficient gene for the production of a protein in the muscles called dystrophin. (Lucas-Heron, 1995) It affects about one in 3600-6000 live male births, making it the most common form of muscular dystrophy. Symptoms are most often noticeable by the time patients reach the age of three to five. The affected males will lose their ability to walk by eight to…
