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

Indian Pacing and Electrophysiology Journal
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

Scanning of paroxysmal atrial fibrillation as an etiological risk factor in patients with acute ischemic stroke: prospective study

São Paulo Medical Journal, 2022
BACKGROUND: Prevention of recurrence of stroke depends on recognition of the underlying mechanism of ischemia. OBJECTIVE: To screen patients who were hospitalized with diagnosis of acute ischemic stroke in terms of atrial fibrillation (AF) with repeated

Ambulatory electrocardiography in the elderly: an audit

International Journal of Clinical Practice, 1989
In a retrospective analysis of 264 episodes of ambulatory electrocardiography (AECG) in 252 elderly out-patients the overall diagnostic yield was only 12 per cent. However, AECG was found to be of significant value in detecting symptomatic tachyarrhythmias, and in confirming the diagnosis of the 'sick sinus syndrome'.

24-hour ambulatory electrocardiographic monitoring is unhelpful in the investigation of older persons with recurrent falls

, 2008
Although frequently used in the assessment of patients with falls, it is unclear whether 24-hour ambulatory electrocardiography contributes to their assessment in older persons.

24-hour electrocardiographic study in myotonic dystrophy

, 1988
Thirty-eight consecutive adult patients with myotonic dystrophy were included in a study with electrocardiography at rest and 24-hour ambulatory electrocardiography. The patients were subdivided into three groups according to the severity of the disease.

Sports Activity Recognition Using Textile‐Based Sensor Fusion and Complex‐Valued Residual Convolutional Neural Networks

Advanced Intelligent Systems, EarlyView.
Motion artifacts in electrocardiographic signals, conventionally dismissed as noise, are shown to encode discriminative activity information. A smart t‐shirt fusing textile strain sensors with textile ECG electrodes, processed through a complex‐valued residual network, recognizes 12 sport activities.
