over the right sternal border and the second intercostal space(n.b. it seems paradoxical from the anatomy of the heart, where the aortic valve comes out from the left ventrical, but think of it as the aorta come out of the ventricle, it actually crosses over a bit to the right so it can form the arch of aorta
The other chest lead used in the emergency room is V2. Both V1 and V2 are placed on the anterior chest wall to provide important information about the heart's electrical activity, particularly in assessing conditions such as myocardial infarction. V1 is positioned in the fourth intercostal space at the right sternal border, while V2 is placed in the fourth intercostal space at the left sternal border.
The heart valves can be approximated on the chest surface using specific auscultation points. The aortic valve is located in the second intercostal space at the right sternal border, the pulmonary valve is found in the second intercostal space at the left sternal border, the tricuspid valve is located at the fourth intercostal space near the left sternal border, and the mitral valve is situated at the fifth intercostal space in the midclavicular line on the left side. These locations help healthcare providers listen for heart sounds and assess valve function.
According to ACC guidelines: 2 channel monitor (5 lead wires) White: 1st intercostal space, mid-clavicular on right Black: 1st intercostal space, mid-clavicular on left Green: Lower right at the last rib, just anterior of the mid-axilary line (ground lead) Brown: 4th intercostal space, right sternal border Red: Lower left at the last rib, just anterior of the mid-axilary line I have never seen Holter leads placed as described below, but you should check with your Holter manufacturer guidelines.

The pulmonary valve is best heard in the second left intercostal space along the left sternal border. This location is known as the pulmonic area.
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.
The heart sounds are heard at something called the 4 corners of the chest around the sternum.1) the aortic valve is heard at the 2nd intercostal space at the right sternal margin.2) the pulmonary valve is heard at the 2nd intercostal space at the left sternal margin.3) the mitral valve is heard over the heart apex which is in the 5th intercostal space in line with the middle of the clavicle.4) the tricuspid valve is typically heard in the right external margin of the 5th intercostals space.See the link below:
In the forth intercostal space, right to the sternum, probably.
The first chest lead, known as 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. Proper placement is crucial for accurate interpretation of the ECG and to diagnose any potential cardiac issues.
It's an area on the chest where the heart beat can be auscultated with a stethoscope. It's located at the left sternal border in the 3rd intercostal space.
