QRS complex and T wave in lead I. Predominantly upward P wave, QRS complex and T wave in aVR. This is opposite of what is seen in a normal ECG. The above findings are similar to that seen in a ...

Lead augmented vector right (aVR) is a useful measure in the diagnosis of ST-segment elevation acute myocardial infarction (STEMI), indicates a new analysis of data from the HERO-2 trial.

She returns for a follow-up visit for palpitations, and a 12-lead ECG is obtained ... negative in leads I and aVF and positive in leads aVR and V1 (^). A second atrial waveform is superimposed ...

The standard ECG has 12 leads ... The six limb leads are called lead I, II, III, aVL, aVR and aVF. The letter “a” stands for “augmented,” as these leads are calculated as a combination ...

The purpose of this study was to evaluate whether the 12-lead ECG could be substituted by ECG sets with a limited number of leads. Materials and methods: The performance of three ECG systems (ie ...
