sufficient background and information about cardiac pacemakers to allow interpretation of electrocardiograms (ECGs) and telemetry strips of normal pacemaker behavior. For more in-depth information‚ such as would be necessary for programming pacemakers‚ a standard pacing text should be consulted. Several of these are listed in the bibliography. Most italicized terms are defined in the glossary at the end of the chapter. Anatomy The pertinent anatomy for cardiac pacing includes the sinoatrial (SA) node

two different types of endoplasmic reticulum; the smooth ER and the rough ER. The smooth endoplasmic reticulum is plentiful in membrane bound enzymes (Koolman & Rohm‚ 2005). These enzymes catalyze incomplete reactions in lipid digestion and biotransformation (the chemical alteration of a substance within the body) (Koolman & Rohm‚ 2005). The smooth endoplasmic reticulum are the sections that have no ribosomes attached (Koolman & Rohm‚ 2005). The smooth ER can be found in both plant and animal cells

We have more than 600 muscles in our bodies. They pump blood throughout your body‚ and help you lift heavy things like backpacks‚ and textbooks. You could control some of your muscles‚ while others like your heart‚ have their own jobs without us thinking at all. Muscles are all made up of same material. A type of tissue like the material in a rubber band. Thousands or tens of thousands of small fibers make up all or each muscle in our body. There are different muscles‚ fibers‚ and contractions.

is not perfect and problems may arise. However before its flaws can be mentioned and analysed. It would be prudent to understand how the heart functions in the first place before going in depth into the various problems that might arise within the cardiac cycle. Of which a large number are covered under the various Arrhythmias‚ which can be divided into two major groups‚ ventricular arrythythmias and supraventricular arrythythmias. I.e.‚ arrythythmias that occur in the ventricles and arrythythmias

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

Sudden cardiac arrest is the largest cause of nature death in the United States‚ causing about 325‚000 deaths in the United States annually. Half of all heart disease deaths are caused by sudden cardiac arrest. (Cleveland Clinic) Sudden cardiac arrest is the sudden‚ unexpected loss of heart function‚ which is caused by abnormality in heart rhythm which is a result from problem with heart’s electrical. Sudden cardiac arrest is more frequent in adults in their mid 30’s and 40’s and is more likely
