Summary

The method of ECG recording with the use of three bipolar leads A (anterior), D dorsalis) and J (or I - inferior) was introduced in 1938 by German electrophysiologist W. Nehb. Being positioned on the chest in the immediate proximity to the heart, and being aligned to the anatomic position of the heart, these leads are very sensitive and allow accurate diagnostics of different heart conditions. All the active leads are placed on anterolateral plane of the chest wall requiring little anatomical window making this technique convenient for express diagnostics using compact electrocardiographic devices without any loss of valuable information.

Active electrodes are located on the chest in the following order: 1st- red standard electrode placed in the second intercostal space to the right from sternum corresponding to V1 for standard 12-lead ECG recording, 2nd- green standard lead placed in the position corresponding to V4; 3rd- yellow in the position V7. Then ECG recorded as if in the I standard lead would be defined as Nehb's D, which records the potential on the posterior left ventricle wall; II standard lead would produce Nehb's A which corresponds to the potential on the anterior wall of the left ventricle, and III standard lead would record Nehb's J, which reflects the potential on the diaphragmatic surface of heart.

Been simple and informative, this ECG recording modality may be applicable for usage with compact portable cardiographer devices for express diagnosis in different situations and may allow faster and more adequate outpatient response in the case of emergencies.

Nehb 3 leads ECG can provide the clinician with portable, reliable, comprehensive and constant ECG monitoring and by this facilitate rapid diagnosis and treatment of STEMI.
