History of electrocardiography dates back to 1616 when Harvey discovered blood circulation, and later in 1887 Waller recorded the electrical activity of human heart for the first time. Since then continuous developments have led to the present state of electrocardiography. I

Anna Wardowska,Piotr Trzonkowskiach heartbeat. The seat of the current generation in the heart is SA node. The current from SA node is passed to the atrium and the AV node to the bundle of His to the bundle branches to the Purkinje fibers and to the ventricular myocardium, and depolarization is completed. This is followed by phase

Introduction and disease overview,normal values for the species of the animal under examination, it is said to be an abnormal electrocardiogram. Tall P wave (>0.4 mV), broad P wave (>0.04 s), tall R wave (>2.5 mV in dogs of small breeds or >3.0 mV in dogs of large breeds), and broad QRS (>0.06 s), deep Q, or S wave are indicative of

Similarly many physical (hypothermia or hyperthermia) and chemical agents (arsenic, lead, bufotoxins, theobromine) adversely influence the electrocardiogram. Many drugs have been found to be associated with ch
