Background and purpose: The relevance of skin preparation by abrasion preceded or not by alcohol cleansing for digital ECG (dECGs) variables was prospectively evaluated. Methods: In 22 healthy male subjects (40.2±9.7 years) dECGs were recorded continuously over 5 minute periods at 5 different time points at 3 separate 24-hour visits, employing 2 electrode types and no skin preparation, abrasion and alcohol cleansing before abrasion. Smoothed means dECG data covering 5 minutes used for statistical analysis on leads V2-3 and V5. Results: Significant of skin preparation with reductions for skin-impedance and noise (p<0.0001 – p=0.35) for all leads, and with no further effect by alcohol cleansing (p>0.46). PRintervals were significantly prolonged by skin preparation (p=0.0003 – p=0.0165) in leads V2-3 at 120 and 1 440 minutes; with additional impact of alcohol at 1 440 minutes (p=0.0005). Subject comfort was markedly higher with one of the electrode types (p<0.0001). Conclusion: Skin preparation by abrasion should be employed prior to dECG recordings to improve signal properties. Cleansing with alcohol is generally not warranted. Skin irritation is dependant on choice of electrode.
