P-wave trending: a valuable tool for documenting supraventricular arrhythmias and AV-conduction disturbances

A technique is described for measuring the P-wave amplitude in ambulatory electrocardiogram recordings. The technique is similar to existing ST-trending methods. Several examples are given of P-wave trends and associated arrhythmias. P-amplitude trends proved very useful in documenting supraventricular ectopic rhythms and episodes of atrioventricular dissociation and atrial fibrillation. The method can be implemented easily in many existing Holter analysis systems.<
