The Use and Types of Electrocardiograms

Biometric systems are technologies that can scan physiological, chemical or behavioral characteristics of a subject for the sake of verifying or in other words authenticating their

At the latter end of the p-q interval, atrial contraction occurs forcing additional blood into the ventricles. At the beginning of the QRS interval on an ECG reading, the mitral valve closes and the ventricles are at EDV (135ml). During the QRS interval, ventricular contraction occurs increasing the pressure in the ventricle and the aorta. When the pressure continues in the ventricle exceeds the pressure in the arteries, the aortic valve opens and blood is ejected. The increased pressure continues through the t peak. The ventricles are now in ESV (65ml) and the aortic valve is closed. Now the ventricles are relaxed causing pressure to fall and the cardiac cycle starts over again. This ECG reading was from a normal tracing. Keep in mind that an ECV is easy to obtain, but there are some subtleties that are very complex.

Patient care technicians (PCT’s), formally known as nursing assistants, are the backbone to any nursing department. They create rapport with the patients and family members, as well as the nursing and medical staff. Some of the tasks PCT’s are responsible for include: obtaining and recording vital signs, collecting and labeling specimens, blood glucose specimen, and obtaining electrocardiograms (ECG). All these tasks are important and critical in an emergency. PCT’s designated to work in medical surgical floors may not remember the steps for obtaining a good ECG reading. Like the saying goes: if you don’t use it, you lose it. The most common reason ECG’s are misinterpreted is due to incorrect lead placement. PCT’s in critical settings such

Biometrics is a method of identifying an individual based on characteristics that they possess, typically physiological features such as a fingerprint, hand, iris, retina, face, voice, and even DNA. Some methods of biometrics security even use multiple physiological features or multimodal biometrics to provide superior security than a single form of biometrics can provide. Why are biometrics important in the field of information security? Biometrics provide a remarkable amount of security for information because biometrics are unique to each person, and thus cannot be lost, copied, or shared with another individual. This security allows for biometrics to provide a means to reliability authenticate personnel. The importance of biometrics can be further divided into the history of biometrics and why it was devised, past implementations of biometrics, current implementations of biometrics, and future implementations of biometrics.

Protected Health Information of the research subjects will be used initially to identify the medical records and echocardiographic studies. Apart of medical record numbers, no other identified data or protected health information will be collected or stored. Some of the investigators will collect echocardiography data and others will collect demographic and clinical data. Therefore, medical records number is needed to accurately combined all data. In addition, medical records numbers are needed to re-verify the accuracy of the collected data if needed. All collected data will be stored on password protected computer on the Rush REDCap website. Only the investigators will have access to the collected data. The patient information will

An ECG/EKG Technician monitor their patient's heart by performing a procedure that is harmless. They run several diagnostic heart test to patients that are going into surgery. ECG/EKG techs also run test on people with heart problems, the test helps them identify and monitor any medical problems that relate to the heart.

Cardiac dysrhythmias come in different degrees of severity. There are heart conditions that you are able to live with and manage on a daily basis and those that require immediate attention. Atrial Fibrillation is one of the more frequently seen types of dysrhythmias (NIH, 2011). The best way to diagnosis a heart condition is by reading a cardiac strip (Ignatavicius &Workman, 2013). Cardiac strips play an chief part in the nursing world allowing the nurse and other trained medical professionals to interpret what the heart is doing. In a normal strip, one can clearly identify a P wave before every QRS complex, which is then followed by a T wave; in Atrial Fibrillation, the Sinoatrial node fires irregularly causing there to be no clear P

The atrial contraction is represented by the P wave. This is an upward, or positive wave of the line on the graph. The ventricular contraction is displayed by the QRS complex. The QRS

Electrocardiographic (ECG) is valuable, cheap, and noninvasive method used in diagnosis and risk stratification of ACS; accordingly it provides useful information regarding culprit artery by evaluation these ECG changes in regarding diagnostic angiography.

Regular electrical impulses are sent within the conduction system of the heart prompting contraction (Marieb, 2015). These electrical signals can be identified and documented by the use of an electrocardiography (ECG) machine. In a familiar ECG recording, three waves will occur; The P wave, QRS complex and

The other way of diagnostic testing is usually 24 hour monitoring using a form of tape recorder called a Holter monitor, which can be used to record the ECG constantly during a 24-hour period. If these symptoms occur during

Once at the hospital tests will be done to rule out other chest pain related causes. The first test that will be done is an Electrocardiogram or an EKG, which records the hearts electrical activity. Damaged heart cells are not able to produce electrical impulses which will produce abnormal EKG results. Elevations in the ST waves on an EKG are classified STEMI and are present in over ninety percent of myocardial infarctions who had a complete occlusion to an artery (Cardiac Emergencies, n.d.). NSTEMI is where there is no elevation of the ST wave and is indicative that a full occlusion has not occurred (Cardiac Emergencies, n.d.).

Recording an electrocardiogram or ECG, is a procedure which is performed daily all over the United Kingdom by thousands of healthcare workers and in particular nurses (Jacobson, 2000). The way in which this procedure is performed varies from geographical location to location and occasionally even more so, between staff on the same ward (Amos, 2000). This reason stated by Amos (2000), formed the basis of my decision to choose this topic.

The electrocardiogram (EKG) is a simple test that measures the heart's electrical activity (Donahue p. 35). The most widely used screening test is the exercise EKG, or stress test.

Now that the experiment has been tested, the results are in there comes the analysis part of the process. After I had determined my calculation I saw where my beats per minute were over a hundred; this consider me to be Tachycardia. Tachycardia refers to an abnormally fast resting heart rate. When examining what Tachycardia was and how it can be affected made me see that different scenarios will affect the beats per minute. Anxiety, caffeine, stress can all cause someone to have such a rapid heartbeat. I remember from when taking the echocardiogram that I was stressed
