When optimal immobilization and contact were obtained, standard bipolar (I-III) and augmented unipolar (aVR, aVL, and aVF) limb leads
As mentioned previously, a unipolar limb lead
records the electrical potential at a single exploring (positive) electrode on one of the limbs minus the average potentials of the other two limb leads
If this were to happen from the point of view of convenience, then some form of mapping of limb lead
measurements from the conventional to the Mason Likar approach would need to be undertaken or else completely revised limits of normality, particularly for limb leads
, would need to be developed.
Steel needle electrodes were inserted subcutaneously to obtain standard bipolar limb lead
DIAGNOSIS: Atrial fibrillation with a ventricular response of 104 beats/minute; Ashman's phenomenon; 1 RV6 > RV5 suggests left ventricular enlargement, (2) right axis deviation (106[degrees]) of the QRS complex with large S waves in leads V5 and V6 indicates right ventricular enlargement; (3) and large QRS voltage in the precordial leads compared to the limb leads
implies a dilated cardiomyopathy.
A 12-lead electrocardiogram (ECG) showed a sinus rhythm with S1Q3T3 pattern in limb leads
and inverted T waves in right precordial leads (V1 to V4).
