The results of examination and treatment a patient with combination accelerated idioventricular rhythm atrial conduction disorder, which made it difficult to interpret the Holter monitoring data, are presented.

BACKGROUND AND PURPOSE Many ischemic strokes or transient ischemic attacks are labeled cryptogenic but may have undetected atrial fibrillation (AF). We sought to identify those most likely to have subclinical AF. METHODS We prospectively studied patients with cryptogenic stroke or transient ischemic attack aged ≥55 years in sinus rhythm, without known AF, enrolled in the intervention arm of t...

The effects of isoprenaline on the induction of supraventricular tachycardia by programmed stimulation were studied in 67 patients to see whether they correlated with spontaneous catecholamine mediated symptoms during exercise testing and Holter monitoring. Thirty seven control patients (group 1) did not have spontaneous arrhythmias either during exercise testing or Holter monitoring. Thirty pa...

The frequency and characteristics of asymptomatic ischemic attacks were investigated in 39 patients with effort angina. During 24 hour Holter monitoring, 32 of the 39 patients displayed one or more episodes of ischemic ST depression. Eight patients had attacks (n = 25) always accompanied by pain; 9 patients had only asymptomatic ischemic episodes (n = 40) and 15 patients had both symptomatic (n...

Electrophysiological abnormalities in cirrhosis, such as the prolongation of the QT interval, are associated with higher risk of ventricular arrhythmias. Holter monitoring offers a full picture of these during 24 hour. Our study aimed to evaluate the extent of the QT interval prolongation, identify etiological and biochemical elements linked with it, and investigate the correlation with ventric...

BACKGROUND Patients with Duchenne Muscular Dystrophy (DMD) develop cardiac fibrosis and dilated cardiomyopathy. We described the frequency of significant Holter findings in DMD, the relationship between cardiac function and arrhythmia burden, and the impact of these findings on clinical management. METHODS AND RESULTS A retrospective review was done of patients with DMD who received a Holter ...

BACKGROUND Cost-effectiveness acceptability curves (CEACs) describe the probability that a new treatment or intervention is cost-effective. The net benefit regression framework (NBRF) allows cost-effectiveness analysis to be done in a simple regression framework. The objective of the paper is to illustrate how net benefit regression can be used to construct a CEAC. METHODS One hundred patient...

PURPOSE To determine the diagnostic yield of the 24-hour Holter monitoring in the patients who were evaluated for palpitations. METHODS A prospective, single-centre study was performed to evaluate the diagnostic yield of the Holter monitoring. The inclusion criteria was age greater then 18 years with the symptom of unexplained recurrent palpitations. The exclusion criteria was patients with k...

Comparison of Average Heart Rates Determined by Surface ECG and 24-Hour Ambulatory ECG (Holter) in Dogs with Spontaneous Atrial Fibrillation. (December 2010) Adriana Lucía Perea Lugo, B.S., Autonomous University of Zacatecas Chair of Advisory Committee: Dr. Theresa W. Fossum The purpose of this study was to compare the heart rates of dogs presenting with spontaneous atrial fibrillation (AF) by ...

OBJECTIVE To investigate the mechanisms of Holter ST shift in patients with acute myocardial infarction treated by thrombolysis. DESIGN Prospective observational study. SETTING A London district general hospital. SUBJECTS The study group consisted of 94 patients with acute myocardial infarction treated by thrombolysis. INTERVENTIONS All underwent early 48 hour Holter ST monitoring and e...
