Limb and left precordial leads
Nettet심전도(心電圖, 영어: electrocardiogram, ECG, 독일어: Elektrokardiogramm, EKG)는 정해진 시간에 심장의 전기적 활동을 해석하는 것이다. 심전도는 피부에 부착된 전극과 신체 외부의 장비에 의해 기록된다. 기록은 이렇게 몸에 침투하지 않는 장비로 만들어지며 이 과정에 대한 용어를 심전도라고 한다.

The following deviations from normal were found: lower voltage and longer duration of P waves in all leads; lower voltage of R waves in all precordial leads and almost all limb and unipolar leads; deeper S waves over … Nettetpatients, outflow obstruction has been found in the left and in the right ventricles [14, 42]. The electrocardiogram (ECG) is unique. Giant QRS complexes are found in the precordial leads and one or two limb leads. The pattern shows biven- tricular or left ventricular hypertrophy. In the left preeordial Table 1.
NettetThe V stands for vector here. In aVR, the left leg lead and left shoulder lead BOTH provide the negative pole for the EKG while the right shoulder is positive. The augmented vector leads require THREE poles to work: two negative and one positive. The precordial leads, asked about in the original question, are UNIPOLAR leads.
