EKG
Electrocardiogram, used to study and record the electrical activity of the heart.

electrocardiogram (ECG, EKG) [e-lek″tro-kahr´de-o-gram″]
the record produced by electrocardiography; a tracing representing the heart's electrical action derived by amplification of the minutely small electrical impulses normally generated by the heart.
Normal electrocardiogram. Heart action during P-R interval: (1) Atrial contraction begins at peak of P wave. (2) P-R interval—atrial contraction. (3) Ventricles relaxed. Heart action during QRS complex: (1) Ventricular contraction begins at peak of R. (2) A-V (mitral and tricuspid) valves close, causing S1 sound. (3) Ventricles contract. (4) Atrial relaxation begins. Heart action during S-T segment: (1) Semilunar valves open (aortic and pulmonic). (2) Ejection of blood from ventricles–systole. Heart action during T wave: (1) Slowing of ejection from ventricles. (2) Closure of semilunar valves (aortic and pulmonic) causing S2 sound. Heart action during T-P interval: (1) Relaxation of ventricles. (2) A-V valves open. (3) Filling of ventricles, causing S3 sound.
