Alternating Wenckebach period (AWP) is a phenomenon that is not rare and can explain a variety of rhythm disorders. It can be recognized from a clinical electrocardiogram (ECG) and may facilitate the interpretation of previously obscure rhythm disturbances, thereby aiding in the management of the patient with arrythmia.

The ECG has been recognized as a valuable diagnostic tool since the end of the 19th century. The normal ECG waveform consists of P, QRS, and T waves (and sometimes U waves)—P waves result from atrial depolarization, QRS complexes from ventricular depolarization, and T waves from ventricular repolarization.

Electrocardiography in turtles
Life Sciences, 1963Abstract The normal ECG of turtles is similar to that of man, but low voltage waves are the rule. The Q and S waves are uncommon. Sex differences are described. In the female the P-R interval is shorter, but the R and T waves are longer and have a lower voltage Unfed males and females show occasional arrhythmias and marked electrical differences from

Veterinary Clinics of North America: Equine Practice, 2019
Analyzing electrocardiographic (ECG) recordings, making a diagnosis and assessment of any arrhythmias present, is an important part of the workup of many equine cases. Accurate analysis requires a good-quality recording, free of as many artifacts as possible, with clear P-QRS-T complex morphology.

This article examines the role of electrocardiography in patient monitoring during an operative procedure. In addition to providing a wealth of physiological information, including information on the electrical activity of the heart, the ECG assists in monitoring and detecting a variety of changes, such as cardiac arrhythmias, electrolyte changes, and ...

Electrocardiography of the fetus
Biomedical Engineering, 1968External electrocardiography of the fetus is a safe and accurate method of investigating the obstetric state during pregnancy and labor. By means of electrocardiography of the fetus the presentation of the fetus, the existence of multiple pregnancy, and disturbances of cardiac activity can be determined.

Electrocardiography In Athletes
JAMA: The Journal of the American Medical Association, 1973To the Editor.— Few professionals in medical care will be dissuaded from routine electrocardiography of athletes by Dr. Gordon Cumming's argument that it is unrealistic both by cost benefit and subject benefit criteria. We physicians know that no decisions today are based on costs or benefit to the patient.

Physics of Electrocardiography
2009If there is any word that strikes fear in the hearts of many students in the health care field, it is “physics.” Much of this fear is unnecessary, at least in relation to the ECG, because a thorough understanding of the physical basis for the ECG provides an important foundation for the understanding and interpretation of ECGs.
