Where should ECG leads be placed?

Proper 12-Lead ECG Placement

V1 4th Intercostal space to the right of the sternum
V2 4th Intercostal space to the left of the sternum
V3 Midway between V2 and V4
V4 5th Intercostal space at the midclavicular line

Where do you put Holter leads?

Left leg electrode positioned on lower left rib cage may lessen amount of artifact; however, to be comparable with a standard 12-lead ECG lead II, the LL lead should be placed on the lower left side of the body, as close to hip as possible.

Where do the 3 ECG leads go?

The recommended 3-wire ECG lead placement is as follows. Place RA (white) electrode under right clavicle, mid-clavicular line within the rib cage frame. Place LA (black) electrode under left clavicle, mid-clavicular line within the rib cage frame.

What happens if ECG leads are put on incorrectly?

The analysis of ECG signals recorded from misplaced electrodes can lead to misinterpretation or even to significant diagnostic errors like incorrect recognition of anterior infarction, anteroseptal infarction, ventricular hypertrophy [9, 14], false diagnosis of ischemia, or Brugada syndrome [16, 24].

Where do female ECG leads go?

For females, place the leads under the breast tissue. You may need to lift and clean the skin underneath the breast to get a clear tracing. A quality 12-lead ECG has a smooth, flat baseline (called the isoelectric line).

What does a 3 lead ECG monitor?

Patients who have cardiac, pulmonary, or electrolyte problems or who undergo surgery may need continuous cardiac monitoring to screen for arrhythmias. Unlike a 12-lead electrocardiogram (ECG), which views the heart from 12 angles, a 3- or 5-lead ECG views it from one to three angles.

What should be the position of the lead during an ECG?

Lead placement and patient positioning should be the same for subsequent ECGs on any individual patient. During the procedure, record any clinical signs (e.g. chest pain) in the notes or on the ECG tracing itself.

How many limb electrodes are needed for an ECG?

By using 4 limb electrodes, you get 6 frontal leads that provide information about the heart’s vertical plane: Leads I, II, and III require a negative and positive electrode (bipolarity) for monitoring. On the other hand, the augmented leads-aVR, aVL, and aVF-are unipolar and requires only a positive electrode for monitoring.

Where is the best place to place an electrode?

1 The limb leads can also be placed on the upper arms and thighs. However, there should be uniformity in your placement. 2 For female patients, place leads V3-V6 under the left breast. 3 Do not use nipples as reference points in placing electrodes for both men and women as nipple locations vary from one person to another.

How to place lead in upper left arm?

1 Place limb leads on soft tissue surfaces & not the bone according to the diagram on above. 2 White RA = Upper Right Arm. 3 Black LA = Upper Left Arm. 4 Red LL – Lower Left Leg. 5 12 Lead ECG Placement. 6 (more items)
