BACKGROUND Myocardial lipid metabolism appears abnormal in dilated cardiomyopathy (DCM). A dual-tracer approach with two different fatty acid analogs may allow us to observe such alteration in vivo. 15-(Ortho-123I-phenyl)-pentadecanoic acid (oPPA) and 15-(para-123I-phenyl)-pentadecanoic acid (pPPA) have similar kinetics in circulation, diffusion, and(More)
In patients with automatic implantable cardioverter defibrillators, insulation of the epicardial patch electrodes (patches) prevents externally applied current from passing through the electrode to the cardiac muscle so that external transthoracic and even internal defibrillation can be unsuccessful. Because emergency cardiac pacing may be required in such(More)
Whether the safety and efficacy of implantable cardioverter defibrillator (ICD) therapy can be assured with lower output devices is an important question. The purpose of this study was to evaluate whether programming the device output at twice the augmented defibrillation threshold was as safe and effective as using the maximum energy. Patients indicated(More)
OBJECTIVES To investigate the effect of intracoronary dipyridamole on the incidence of abrupt vessel closure, myocardial infarction, necessity for bypass grafting, and death following percutaneous transluminal coronary angioplasty (PTCA). PATIENTS Patients were randomly allocated to receive either conventional pretreatment (heparin 15 000 IU and aspirin(More)
In patients with acute or chronic myocarditis, arrhythmias are a common and often the only clinical symptom in the natural course of the disease. The potentially malignant tachy- and bradyarrhythmias are of particular significance in the differential diagnosis of sudden cardiac death in myocarditis. Factors responsible for the increased incidence of cardiac(More)
UNLABELLED Hypertension, especially if associated with left ventricular hypertrophy (LVH), is a risk factor in complex ventricular arrhythmia (VA) and sudden cardiac death (SCD). To determine the effectiveness of the clinical use of programmed ventricular stimulation (PVS) we studied 40 symptomatic hypertensive patients after excluding coronary heart(More)
For evaluation of patients with an increased risk of sudden cardiac death, the analyses of ventricular late potentials, heart rate variability, and baroreflexsensitivity are helpful. But so far, the prediction of a malignant arrhythmic event is not possible with sufficient accuracy. For a better risk stratification other methods are necessary. In this study(More)
To elucidate the incidence and clinical significance of ventricular late potentials (LP) and reduced heart rate variability (HRV) in primary and secondary heart muscle disease, 157 patients with dilated cardiomyopathy (DCM, n = 19), chronic myocarditis (MC, n = 50), hypertrophic cardiomyopathy (HCM, n = 27) and systemic hypertension (HT, n = 61) were(More)
Reduction of the defibrillation energy requirement offers the opportunity to decrease implantable cardioverter defibrillator (ICD) size and to increase device longevity. Therefore, the purpose of this prospective study was to obtain confirmed defibrillation thresholds (DFTs) of < or = 15 J in each patient with an endocardial dual-coil lead system(More)
OBJECTIVE The aim of this study was to evaluate if administration of adenosine during sinus rhythm to patients with PSVT of unknown mechanism is capable to detect dual AV nodal conduction and furthermore to evaluate this diagnostic parameter as a controlling test after slow pathway ablation in AVNRT.
