Twelve-lead ambulatory ECG recording using a seven-electrode recorder: An alternative method for electrophysiological evaluation.

ABSTRACT:

Introduction

Conventional three-lead ambulatory electrocardiogram recording (3L-AECG) is used for the quantitative diagnosis of arrhythmias. However, the lack of crucial information, such as QRS morphology and orientation, renders the 3L-AECG incomplete for planning electrophysiological interventions. The 12-lead AECG (12L-AECG) merges the temporal resolution 3L-AECG with the spatial resolution of the standard electrocardiogram (S-ECG). Although it provides more detail, it is not widely used. This study aimed to verify whether the seven-electrode 12L-AECG and S-ECG have similar waveforms.

Methods

A questionnaire consisting of 240 side-by-side comparisons (12 leads from 20 patients) was created. These consisted of a QRS registered using the 12L-AECG and a QRS from the same pa
