BACKGROUND The 24hr ECG Holter monitoring system is helpful in assessing cardiac arrhythmias patients presenting with palpitation, dizziness, presyncope and syncope, which are not detected by standard office electrocardiogram.
 METHODS This was a single center prospective observational study conducted to assess the prevalence of among 78 consisting 41 males 37 females referred for 24 hr BP...

For two centuries after Harvey the arterial pulse was often regarded as independent of the heart beat. This misunderstanding was mainly because of the frequent failure of the irregular heart to elicit a radial pulse: the "pulse deficit" of later times. Harvey observed ineffective palpitation of the atrium just before death. This was probably atrial fibrillation. He established the origin of the...

OBJECTIVE To assess the role of caffeine restriction in the management of patients with symptomatic idiopathic ventricular premature beats. DESIGN A randomised, double blind, 6 week intervention trial incorporating dietary caffeine restriction, caffeinated coffee, and decaffeinated coffee. SETTING Cardiac outpatient clinic. PATIENTS 13 patients with symptomatic frequent idiopathic ventric...

A 43-year-old symptomatic woman (dyspnea and palpitation) had multiple coronary-pulmonary artery fistulae with high output; percutaneous embolization was successfully performed using controlled-release microcoils and disposable balloons.

Background Brugada syndrome (BrS) is an inherited channelopathy, which is associated with sudden cardiac death due to rapid polymorphic VT or VF. There is no definite consensus regarding the management of asymptomatic patients. Some experts advocate close follow-up; others propose the programmed stimulation for risk stratification. We aimed to evaluate the benefit of complete atrial and ventric...

In this article, we analyze the arterial pulse in the spectral domain. A parameter, the spectral harmonic energy ratio (SHER), is developed to assess the features of the overly decreased spectral energy in the fourth to sixth harmonic for palpitation patients. Compared with normal subjects, the statistical results reveal that the mean value of SHER in the patient group (57.7 ± 27.9) is signific...
