Electrocardiography

presentation of the heart rhythms, of the normal and abnormal electrocardiograms he had studied the year prior. In this presentation he explained left and right ventricular hypertrophy, left and right atrial hypertrophy, U wave, ventricular premature beats, ventricular bigeminy, atrial flutter, and a complete heart block. Einthoven created a Triangle Imaginary formation. Using a triangle in electrocardiography, it was formed by the two shoulders and the pubis, the shape formed a inverted equilateral triangle, with the heart in the center. This produced zero potential when the voltages are summed. This helps with the misplacement of leads, it helps the doctors know where to place leads to correctly, now in today we use 12 leads etc. This triangle can still help us figure out where to place the leads on the limbs, using fatty tissue. In today electrocardiograms are more advanced than in the 1900’s. Modern electrocardiograms can actually produce a shock when cpr is in progress, to stun the heart and get it back working how it needs to. Since willem einthoven's findings and inventions on the electrocardiography, science has changed and evolved even more so. Today in the modern electrocardiograms, the heart rate is measured on a machine that can be portable, and it even tells you what the heart is doing in its function, it no longer gets sent to a lab, but recorded in patients medical histories, where everyone in the medical field if needed can access it, with HIPPA laws intact…

The ECG/EKG When most people think of heart tests, they think of the ECG. ECG stands for electrocardiogram. It's also called an EKG, from the German elektrokardiogram. Although it may look like an ECG is recording heartbeats, it's not. In fact, it records the electrical activity (the electrical triggers, if you will) that presage the actual heartbeat. The mechanical beats follow the electrical triggers by about a tenth of a second -- unless, of course, there's a problem. Or to state it in…

Electrocardiogram (ECG) is used to identify any irregular heart rhythms. It does this by detecting the electrical activity of the heart as line tracings on paper, for easier analysis (Price, 2012). As Stanfield (2014) reports the cardiac muscle contracts in response to electrical depolarisation of the muscle cells. This electrical activity, when amplified and recorded, is known as an ECG. According to Maron et al, (2014) an ECG test can help detect the cause of symptoms such as chest pains or…

Dear Heart, I’ve began my journey to become a Medical Assistant, and today I started out with the Electrocardiography class. For years I knew you were important to me, but in only one class period I learned so many new things about you that in nineteen years I had no clue about! Today’s lesson taught me a few of the things you do in there for me, about how you pump blood for me, panic, and relax for me. Therefore, I plan to care for you for many years to come, by mostly taking things steady,…

Sudden cardiac deaths in young athletes still remain unsolved, the effect of high intense training puts the heart under immense stress. In both the United States and Europe it has been reported these deaths are usually due to undetected cardiovascular disease and seem to be increasing (Maron et al. 2007) Many prevention methods have been created to reduce the risk of cardiac deaths in young athletes, such as Pre-participation screening like, the electrocardiography (ECG) screening programme in…

I am going to be doing Long QT Syndrome because it is something I can relate to in real life. Long QT syndrome is a disorder of your heart and affects electrical activity. The symptoms of Long QT are dizziness, unexplained fainting, feeling faint, and black outs WIth a bad enough symptom and no treatment then it can cause uncontrollable arrhythmias and maybe even death. A fun fact is that I actually have long QT Syndrome. So every year I go to the cardiologist to get a heart monitor. I also…

The electrocardiography allows an administer to record the cardiac conduction cycle via graph. The graph is composed of three labels referred to as waves that identify conduction. The labels are P wave, QRS complex, and T wave. The P wave indicates the atrial depolarization. The time span of the P wave is about 0.08 seconds and is caused by depolarization wave actions from the SA node to the atria. Shortly after the P wave starts, the atria recoils. The QRS complex is a sign of ventricle…

Intraoperative monitoring: A consensus on standard monitoring requirements has not yet established in the literature. Routine monitoring includes electrocardiography, pulse oximetry, capnography, temperature and urine output monitoring. There are many authors who recommend invasive blood pressure monitoring by indwelling arterial catheter in all patients, irrespective of their age 18.Abrupt changes in cerebral blood flow due to changes in intracranial pressure (ICP) is possible during the…

This includes, Human Samples, Animals, Electrocardiography, Statistics, Western Blotting, and Immunofluorescence. These were all very well developed and analyzed with thoroughness throughout the entire paper. Dr. Fraidenraich and his colleagues wanted to assess the changes in expression and localization of Cx43 in the hearts of several DMD models. To do this, they conducted immunofluorescence (IF) staining on WT, mdx, and mdx:utr mice at 2, 4, 8, and 12 months of age. mdx:utr mice were analyzed…
