Ekg Research Paper

Resting heart contractions were recorded for thirty seconds until the heart rate was less than 60 beats per minute. A stimulator electrode to be used was set to the following states: Amplitude of 4.00 Volts, a stimulus delay of 50ms, stimulus duration of 10ms, a frequency of 1.0Hz, and a pulse number of 30. The electrode was then placed in direct contact with the heart for 30 seconds at which time the data was observed and recorded.

EKG is an electrocardiogram, a machine used to check on problems with your electrical activity with your heart. An electrocardiogram machine translates the heart’s electrical pattern into lines that specific professionals can read it. The first EKG was made by Willem Einthoven, a Dutch Java island (now called Indonesia) born citizen. Willem was born the 21st day of May 1860. His father, Jacob Einthoven, was born and educated in Groningen (Netherlands). His father was also

An electrical stimulus was applied to the heart; the following graph shows the refractory period of the frog’s heart when an extra-systole was induced. It can be seen that right after the recording was marked “Refractory 3,” an extra-systole was detected.

When I did my own EKG lab testing I used the following materials: BIOPAC electrode lead set (SS2L), BIOPAC disposable vinyl electrodes (EL503), Cot, BIOPAC electrodes, Computer Sytem, BIOPAC Student Lab software v3.0 or greater, and BIOPAC acquisition unit (MP30). When all these materials are available the computer was turned on and three of the electrodes were placed on the body of my teammate. Two electrodes were positioned on the medial surface of each leg just above the ankle, and the last electrode was on the right anterior forearm at her wrist. When these were attached the subject was asked to lie down on the cot and relax. We then attached her to the EKG machine with three colored cables. The white cable was placed on the electrode on the right forearm, the black cable was placed on right leg and the red cable was attached to the electrode on the left leg.

12 Lead Electrocardiogram (ECG) - There are typical changes to the normal pattern of the ECG in a heart attack. Patterns that occur include pathological Q waves and ST elevation (Koutoukidis, Stainton & Hughson 2013, p. 505). However, it is possible to have a normal ECG even if a patient has had a heart attack. The indicators for this test include: suspected myocardial infarction, suspected pulmonary embolism, perceived cardiac dysrhythmias, fainting or collapse, a third heart sound, fourth heart sound, a cardiac murmur or other findings to indicate structural heart disease. The

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 EKG is read by a doctor or specialist, such as an internist, family medicine doctor, electrophysiologist, cardiologist, anesthesiologist, or surgeon. The doctor will look at the pattern of spikes and dips on your EKG to check the electrical activity in different parts of your heart. The spikes and dips are grouped into different sections that show how your heart is working

The heart rate is measured with an electrocardiogram, or ECG. This is a machine that measures the electrical impulses from the patient's heart. This is displayed on a monitor or ECG graph paper. The boxes on the graph paper measure time. Five small boxes are equal to one large box. The large box represents two-tenths of a second.

An EKG is a electrocardiogram, which is a test done to the heart. The heart is a muscular pump that transports blood throughout the body. It is made up of four chambers, the upper ones are called atria and the bottom two chambers are called ventricles. The heart has the ability to pump due to a natural electrical system. An EKG is done to measure the electrical activity of a heartbeat. An EKG is done by a is performed in a doctor's office or a hospital. The patient will be dressed in a hospital gown, removing all jewelry and will then have to lay on a medical table where twelve to fifteen electrodes will be attached to their arms, legs and chest. Electrodes are little patches that are used to detected and conduct the electrical impulses. If there is hair

Another problem surgeons faces is the connecting of the circulatory system of the heart. The coordination of atrial and ventricular contractions is necessary for efficient pumping of the blood. Any damage leads to a loss of coordination and diminished heart function. But how do surgeons and doctors come to make sure the circulatory is system is working at its best is by using an electrocardiogram, or ECG. With this procedure, electrodes are placed on key points of the body's surface to monitor the electrical activity of the heart. However, what happens if the low flowing of blood or blockage of the blood comes to happen. Myocardial infarctions, or heart attacks happens, and it its due to the blockage or reduction of blood flow to an area of

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

An echocardiogram is a diagnostic test that is performed to provide a graphic outline of how the heart is moving. This is categorized as an Ultrasound. It Utilizes high-frequency sound waves and it can engender pictures of the heart's chambers and valves. This gives the technician the ability to view how well the heart is pumping. This test is performed for many reasons such as, determining how well the heart is functioning; But, mainly to probe for several variants of heart diseases. Also, this test can prove how efficacious surgical and medical treatments can become consistent; visually examining how heart valve disease is progressing over time. An echocardiogram can take about 30 minutes to an hour to consummate. Patients should not experience

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.

The purpose of these lab exercises is to understand the function and importance of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore, the equipment used in the experiment will show the functions in the right and left arm; as well as, in the right and left ankles. Finally, the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate.
