The relation of precordial and orthogonal leads.
IT has become evident that much of the diagnostic information now obtained from precordial leads may be furnished by an adequate orthogonal lead system.' 3 This is innportant to the further development of diagInostic electrocardiography, since quantitative (lescription of only three variables has obvious advantages over the description of larger riunmbers of body surface leads. At present the o...
متن کاملPrecordial Bipolar Leads for Mobile ECG Applications
ii These results indicate that short IED bipolar leads provide a signal that is adequate for clinical use. Furthermore, the performance of these leads was shown to be similar or even superior to that of the commonly used standard leads. It can be concluded that when correctly positioned, short IED bipolar leads are useful and can give additional value for clinical diagnostics. These results pro...
متن کاملTall Upright T Waves in the Precordial Leads By IVAN
One hundred ten cases of T waves more than 10 mm in height in the precordial leads were studied. The T waves were wide in ischemic heart disease and thin and peaked in uremia. Marked changes in the ventricular gradient were obselved in ischemic heart disease and in uremia with hyperkalemia. In other conditions, the changes in the ventricular gradient were of a lesser degree. In cases of left ve...

متن کاملAtrial fibrillation with QRS voltage low in the limb leads and high in the precordial leads.
n the electrocardiogram illustrated here (Figure), the ventricular rhythm is irregularly irregular with baseline undulation but no definite P waves; thus, the rhythm is atrial fibrillation. No time lines are visible on the tracing, but it was recorded at 25 mm per second and is 250 mm, or 10 seconds, long. Nineteen QRSs occur in the 10 seconds, making the ventricular rate 114 beats per minute. ...
