Chest electrodes are preferred to limb electrodes for cardiac monitoring, as limb movements are not restricted and produce less interference of the E.C.G. trace. Eight types of disposable chest electrodes were investigated to compare their performance, skin reactions, cost, ease of application, size, and skin-electrode impedance.Elema-Schonander electrodes were found to be the most efficient and the most expensive. In their application care was required to avoid severe skin reactions.Dracard electrodes were simple to attach, worked well without severe skin reactions, and were cheap. They are recommended for routine use. Smith and Nephew electrodes, a type of "multipoint electrodes" which do not require electrode jelly, frequently produced severe skin reactions, making them unsuitable for monitoring for periods exceeding 12 hours.
心脏监测时，胸部电极比肢体电极更可取，因为肢体活动不受限制，对心电图描记的干扰也较小。研究了八种一次性胸部电极，以比较它们的性能、皮肤反应、成本、使用便利性、尺寸和皮肤电极阻抗。发现Elema-Schonander电极效率最高但成本也最高。使用时需要小心避免严重的皮肤反应。Dracard电极易于粘贴，使用效果良好且无严重皮肤反应，价格便宜。建议日常使用。施乐辉电极是一种“多点电极”，不需要电极膏，但经常会引起严重的皮肤反应，因此不适合超过12小时的监测。
