Wall The heart is composed of cardiac muscle which enable the heart to contract and allow the synchronization of the heart beat. The heart wall is divided into three layers: the epicardium‚ myocardium‚ and endocardium. * Epicardium - outer protective layer of the heart. * Myocardium - muscular middle layer wall of the heart. * Endocardium - inner layer of the heart that is continuous with the inner lining of blood * Cardiac Conduction * Cardiac conduction is the rate at which

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

The cardiac conduction system of the heart consists of specialized muscle cells that generate and send rhythmic electrical impulses to the myocardium in order for the heart to contract (Cardiac Conduction System‚ 2016). When there is the normal rhythm of the heart it is called sinus rhythm and any deviation from sinus rhythm is called an arrhythmia (Saladin‚ 2012). Electrocardiograms (ECG) record the electrical impulses and help determine when there are any abnormalities in the way the heart functions
Premium Heart Blood Artery
Cardiac This is an involuntary muscle‚ found solely in the walls of the heart‚ as well as in the walls of the blood vessels. This sort of muscle has similarities with the skeletal muscles‚ because it is striated. Furthermore‚ it has slight similarities to the smooth muscles‚ because its contractions are not under conscious control. On the other hand this type of muscle is highly specialised. It is under the control of the autonomic nervous system‚ however‚ even without nervous imput contractions

The Path of the Cardiac Pacemaker The cardiac pacemaker has been around for a very long time and will to continue to be around for even longer. The historical and future path of the pacemaker is endless with possibilities only limited by technology. Every day research labs try to find ways to make the life better for anyone that may need to have one implanted. Around 40% of all human deaths are attributed to cardiovascular diseases. Cardiac pacing has become a therapeutic tool used worldwide with

Cardiac surgeons are people who do treatments and surgeries to treat people with heart and lung disease. They also deal with vessels and organs. There are a lot of different types of operations. There is heart valve repair and replacements‚ heart defect repair‚ coronary artery bypass‚ aneurysm repair‚ heart transplant‚ lungs (lung disease). They complete the most surgeries in their field. Grey’s Anatomy influenced me because in that show it’s a bunch of different types of surgeons and I liked cardio

science staff (cardiac physiologist). A cardiac physiologist’s role comprises of recording and analysing a variety of physiological data required to assist in the diagnosis and treatment of different cardiac diseases (Scst.org.uk‚ 2016). They are qualified to perform a range of non-invasive cardiovascular procedures‚ from electrocardiograms to pacemaker and ICD checks which I have observed during placement. In addition‚ cardiac physiologists are also trained to assist in cardiac catheterization
