Rapid Interpretation of EKG's is a best-selling textbook for over 30 years [1] that teaches the basics of interpreting electrocardiograms. It adopts a simplistic fill-in-the-blank style [ 2 ] and is suited for medical students and junior residents. [ 1 ]
Dale Dubin (born 1940), is a former American plastic surgeon and author of several cardiology textbooks, though never practicing or being trained as a cardiologist. Dubin practiced medicine in Tampa, Florida , [ 1 ] and gained fame within the medical community with the 1972 publication of Rapid Interpretation of EKG's , a best-selling textbook ...
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.
Normal sinus rhythm and ectopic beats - premature ventricular contractions (PVC) and premature atrial contractions (PAC) shown on an EKG. Premature atrial contractions are typically diagnosed with an electrocardiogram, Holter monitor, long-term continuous monitor, cardiac event monitor, or with a smartwatch with an ECG functionality.

Basic signal features of time and amplitude which are measured and form the basis for automated ECG analysis. A digital representation of each recorded ECG channel is obtained, by means of an analog-to-digital converter and a special data acquisition software or a digital signal processing (DSP) chip.
The 2018 European Society of Cardiology/American College of Cardiology Foundation/American Heart Association/World Health Federation Universal Definition of Myocardial Infarction for the ECG diagnosis of the ST segment elevation type of acute myocardial infarction require new ST elevation at J point of at least 1mm (0.1 mV) in two contiguous leads with the cut-points: ≥1 mm in all leads ...
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").
The ST segment starts from the J point (termination of QRS complex and the beginning of ST segment) and ends with the T wave.The ST segment is the plateau phase, in which the majority of the myocardial cells had gone through depolarization but not repolarization.
