ECGs are often mistaken for CCGs. However, while these games are very similar to CCGs and can be seen as their subset (Fantasy Flight Games, for example, defines a "Living Card Game" as "a game that breaks away from the traditional Collectible Card Game (CCG) model" [10]), they crucially lack randomness in the purchase and distribution of the cards.
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.
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 ...
The book was written by Dale Dubin, M.D., a plastic surgeon and convicted felon, [3] who has written several books on cardiology including Ion Adventure in the Heartland: Exploring the Heart's Ionic-Molecular Microcosm [4] and Understanding Cardio-pulmonary Resuscitation. [5]
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 ...
The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane. The hexaxial reference system, better known as the Cabrera system, is a convention to present the extremity leads of the 12 lead electrocardiogram, [1] that provides an illustrative logical sequence that helps interpretation of the ECG, especially to determine the heart's ...
SAECG recording yields a single, averaged QRS potential, usually printed in a much larger scale than standard ECGs, upon which the SAECG software performs calculations to reveal small variations (typically 1-25 uV) in the final portion of the QRS complex (the so-called "late potentials, or more accurately, "late ventricular potentials").
ECG (Electrocardiography) sensors measure the bio-potential generated by electrical signals that control the expansion and contraction of heart chambers, typically implemented in medical devices. PPG ( Photoplethysmography ) sensors use light-based technology to measure the blood volume controlled by the heart's pumping action.
