Electrocardiographic Leads
IN the first paper of this series' it was shown that the relationship between the electromotive forces of the heart and the voltages produced by them in a given lead are completely determined by the electric field set up in the heart when a unit current is introduced into the lead. This means that to analyze the relationship between the electromotive forces and the lead voltage it is only neces...
متن کاملElectrocardiographic Leads III
IN the first and second papers of this series' 2 the concept of the "lead field" was introduced, and it was shown how the behavior of leads may be determined by an analysis of their lead fields. In this final paper, methods for the construction of leads that should be superior to those in common use are described. Although some of these methods are complicated, and to a certain extent mathemati...

متن کاملElectrocardiographic parameters of Markhoz goat using base apex lead and six standard limb leads
Electrocardiographic study of 50 healthy Markhoz goats ranging from less than 1 to more than 3 years inage was carried out. The heart rate varied from 99 to 123 beats/min with a mean of 110 beats/min. There wasa significant difference between the heart rate of goats in 3 age groups (PT waves and QT interval in base apex lead, QRS wave in lead I, P-R and PQ interval in aVF lead were higherand du...
متن کاملVi-like' and VF-like' leads for continuous electrocardiographic monitoring.
An increasing number of patients is being monitored in Coronary Care Units; however, there have been few attempts to standardize monitoring techniques (Marriott and Fogg, I968, I970; Marriott and Thorne, I97I). In most units, the monitoring leads are placed arbitrarily to monitor clear P and QRS complexes. Electrode positioning varies from unit to unit, from patient to patient, and even from da...
