The large yellow book was originally published in 1972; the sixth and most recent edition was published in 2000. In the fiftieth printing, the author hid within the copyright notice an offer to give his prized 1965 Ford Thunderbird (which was featured in several photographs in the book) to anyone who actually read the message and responded.
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [5] using electrodes placed on the skin.
The manufacturing industries of ECG machines is now entirely digital, and many models incorporate embedded software for analysis and interpretation of ECG recordings with 3 or more leads. Consumer products, such as home ECG recorders for simple, 1-channel heart arrhythmia detection, also use basic ECG analysis, essentially to detect abnormalities.
In the fiftieth printing of the book, he hid within the copyright notice an offer to give his prized 1965 Ford Thunderbird to anyone who actually read the message and responded. Out of 60,000 copies in that printing, only 5 readers noticed and responded, and Dubin's own daughter delivered the car to the winner (selected by a random drawing). [ 1 ]
Drawing of the ECG, with labels of intervals. Cardiac electrophysiology is a branch of cardiology and basic science focusing on the electrical activities of the heart.The term is usually used in clinical context, to describe studies of such phenomena by invasive (intracardiac) catheter recording of spontaneous activity as well as of cardiac responses to programmed electrical stimulation ...

When electrical recordings are made from the skin, it is considered to be an ECG as described above. However, electrical recordings made from within the heart such as with an artificial cardiac pacemaker or during an electrophysiology study, the signals recorded are considered an "electrogram" instead of an ECG. These signals are not ...
