Accurate Electrode Positioning Remains Critical For Reliable Cardiovascular Research DataElectrocardiography continues to serve as a foundational technique in cardiovascular research, yet electrode placement errors remain a persistent source of data quality issues across clinical and laboratory settings. Similarly, positioning chest leads V1 and V2 too high on the sternum can produce waveforms resembling myocardial infarction or conduction system blockages, potentially compromising both diagnostic accuracy and research data integrity. Standardised protocols for the placement of ECG leads emphasise systematic identification of anatomical landmarks, beginning with the fourth intercostal space for V1 and V2 positioning.

Proper skin preparation using alcohol swabs to remove oils, combined with precise anatomical marking before electrode application, forms the basis of protocols now standard across cardiovascular physiology laboratories worldwide.
