Normal limits of ECG measurements related to atrial activity using a modified limb lead system
Atrial repolarization is rarely seen clearly on a standard 12-lead electrocardiogram on account of the fact that it is largely obscured by the QRS complex. In the main, during sinus rhythm at a relatively normal heart rate, only 50 ms of an atrial repolarization wave might be seen at the terminal potion of the PR segment. In the vast majority of ECGs, this part of the PR interval is at the same...
متن کاملNormal limits of ECG measurements related to atrial activity using a modified limb lead system
OBJECTIVE The present study was designed to derive the normal limits of a new ECG lead system aimed at enhancing the amplitude of atrial potentials through the use of bipolar chest leads. METHODS Sixty healthy male subjects, mean age 38.85±8.76 years (range 25 to 58 years) were included in this study. In addition to a standard 12-lead ECG, a modified limb lead (MLL) ECG was recorded for 60 se...
متن کاملUnmasking of atrial repolarization waves using a simple modified limb lead system
OBJECTIVE In the present study, a modified limb lead (MLL) system was used to record the Ta wave in sinus rhythm and with AV block in male patients. METHODS Eighty male subjects (mean age 36 ± 7 years) in sinus rhythm and 20 male patients with AV block (mean age 72 ± 5 years) were included in this study. Standard limb lead (SLL) ECGs and MLL ECGs were recorded for 60 seconds each with an EDAN...
متن کاملA modified Lewis ECG lead system for ambulatory monitoring of atrial arrhythmias.
BACKGROUND When using a reduced ECG lead system with three leads or less, the analysis of atrial activity during arrhythmias can become problematic due to low signal amplitude and noise. Long ago, Sir Thomas Lewis proposed a lead system for atrial activity enhancement in which two electrodes are placed directly on the chest, however, these leads are sensitive to arm movement artifacts. In this ...
