Besides the traditional 12-lead EKG, it is also possible to obtain information about the heart’s electrical activity using implantable recording devices. The GAHP cardiac exam submission form requests copies of EKGs that are obtained during anesthetized exams. An EKG can detect irregularities in heart rhythm, also known as arrhythmia.įor great apes, an EKG is often performed during an anesthetized health assessment. An EKG produces a visual display of electrical activity as graphed wave forms and these tracings provide information about heart rate and heart rate variability. The contractions are what we refer to as the heartbeat. Electrical impulses in the heart are what tell the heart muscles to contract. In contrast to a cardiac ultrasound (echocardiogram) which is used to evaluate the mechanical function of the heart, an electrocardiogram is used to evaluate the electrical activity in the heart. The most common EKG is called the 12-lead EKG. In the following decades some other great names as Adolf Beck, Vladimir Vladimirovich Pravdich-Neminsky, Napoleon Cybulski, Jelenska-Macieszyna and Hans Berger appeared. The EEG history starts in 1875 when Richard Caton published on British Medical Journal his discoveries about electrical properties studying rats and monkeys’ brains. It is common to use the German “EKG” in the United States because “ECG” sounds very similar to a different procedure called an EEG.Īn ECG/EKG is a procedure for recording electrical activity in the heart over a period of time using electrodes that are strategically placed on the body. EEG: Electroencephalography, the beginnings of Neuroscience. Both refer to the same procedure, however one is in English (electrocardiogram – ECG) and the other is based on the German spelling (elektrokardiogramm – EKG).
There is no difference between an ECG and an EKG. The authors find that monopolar, but not bipolar, stimulation produces significant artifact during EKG, EEG, and polysomnography. What is the difference between and ECG and EKG?
