In an electrocardiogram (EKG or ECG), the V1 lead is one of the precordial (chest) leads used to record the electrical activity of the heart. It is placed in the fourth intercostal space at the right sternal border. The V1 lead provides valuable information about the right side of the heart and can help in diagnosing conditions such as right ventricular hypertrophy or certain arrhythmias. Its positioning allows for clear visualization of the heart's electrical activity in that specific area.

Occlusion of the left anterior descending (LAD) artery is typically indicated by changes in the EKG leads V1 to V4. These leads reflect the anterior wall of the heart, and ST elevation in these leads can suggest an acute anterior myocardial infarction due to LAD occlusion. Additionally, reciprocal changes may be observed in inferior leads such as II, III, and aVF.
Lead V1 is placed in the fourth intercostal space at the right sternal border. This position allows for optimal recording of electrical activity from the right side of the heart and the interventricular septum. It is one of the six precordial leads used in a standard 12-lead EKG to provide a comprehensive view of the heart's electrical activity.
Right limb leads to left limbs and vice versa with other side. Chest leads run from v1 left sternal to v6 right lateral usingsame landmark placement
Modified Chest Lead - 1 (V1 position)
There are only 10 electrodes and leads, but those 10 leads get 12 different electrical recordings, which makes it a 12-lead ekg.
-RSR(V1) non-diagnostic on an EKG refers to a specific pattern seen in lead V1 that indicates the presence of a small, not well-defined R wave followed by an S wave. This finding is often considered non-diagnostic because it does not provide clear evidence of a specific cardiac condition or abnormality. It may be a normal variant, particularly in certain populations, and typically does not warrant further investigation unless accompanied by other concerning symptoms or findings.
EKG machine leads are electrodes attached to the patient's skin to measure the electrical signals produced by the heart. The leads pick up these signals and transmit them to the EKG machine, which then displays them as a graph that represents the heart's electrical activity. Different lead placements provide different views of the heart's electrical activity.

Close to normal, but not quite.
