Action Potentials During Ventricular Fibrillation in Dogs
This study determined the response of action potentials during ventricular fibrillation (VF) to timed monophasic and biphasic shocks. A floating glass microelectrode was used to record intracellularly from the anterior right ventricle in 10 open-chest dogs. After 10 seconds of electrically induced VF, 5-millisecond monophasic and 2.5/2.5-millisecond biphasic shocks or 16-millisecond monophasic ...
متن کاملImproved Identification of Late Potentials
Background. This study performed a critical analysis of signal-averaging methods. The objective was to optimize detection of late potentials. Methods and Results. We studied two patient populations: a low-arrhythmia-risk group with no evidence of heart disease and a group with clinically documented ventricular tachycardia (VT). Filtered QRS duration (QRSD) and terminal QRS amplitude (RMS40) wer...
متن کاملLate ventricular potentials and heavy drinking.
OBJECTIVES To assess the effects of chronic drinking on detection of low amplitude signals, and to determine the relation between late ventricular potentials (LVP) and liver biopsy findings. DESIGN Prospective study. SETTING General hospital. PATIENTS 41 consecutive chronic alcoholics without known pre-existing heart disease. METHODS About four days after each patient's last alcoholic d...
متن کاملVentricular vulnerability assessed by programmed ventricular stimulation in patients with and without late potentials.
Late potentials can be recorded noninvasively with the averaging technique in about one-third of patients with coronary heart disease in whom ventricular tachyarrhythmias have not been previously documented. The prognostic significance of these findings has not yet been established. Therefore, the presence or absence of late potentials was correlated to the results of programmed ventricular sti...
متن کامل[Prediction of ventricular tachycardia in acute myocardial infarction by ventricular late potentials].
To know the relationship between positive ventricular late potentials (LP) and occurrence of ventricular tachycardia (VT), signal-averaged electrocardiogram (SAECG) was recorded in 214 patients with myocardial infarction (MI). According to the time course of SAECG recording after the onset of MI, the subjects were divided into three groups; acute MI (AMI) group (onset-2nd week, n = 148), recent...
