Echocardiographic Studies in Cardiomyopathies
Cardiomyopathies comprise a large and inhomogenous group of myocardial diseases. The term primary cardiomyopathy has been proposed for those cases in which a causal factor could not be found.

Intracardiac Cardioversion for Ablation of the Atrioventricular Conduction System in Patients with Drug Resistant Atrial Flutter
The technique of intracardiac cardioversion for the ablation of the atrioventricular conduction system was used in three male patients (65, 53 and 57 years of age) with atrial flutter unresponsive to medical m...

Methods for Non-Invasive Detection of Ventricular Late Potentials — A Comparative Multicenter Study
To evaluate the methodological problems of the non-invasive registration of delayed depolarizations the results obtained with four different averaging systems in the same 109 patients (pts) (80 with coronary a...

Chapter
Computertomographic Findings in Congestive Cardiomyopathy
The contribution of non-invasive radiologic diagnostic procedures has thus far been rather insignificant in the diagnosis of cardiomyopathy. The mainstay has been the conventional chest X-ray. Estimation of di...

Prevalence of Arrhythmias During 24-Hour Electrocardiographic Monitoring in Patients with Dilative Cardiomyopathy
Clinical symptoms of dilative (congestive) cardiomyopathy (DCM) were generally attributed to left ventricular pump failure or thromboembolic complications. Only sporadic reports appeared documenting arrhythmia...

Repetitive Response to Ventricular Extrastimuli in Patients with Dilated Cardiomyopathy
In dilated cardiomyopathy ventricular arrhythmias are frequently observed and may lead to sudden death from ventricular fibrillation [2, 3, 5]. Increased ventricular vulnerability therefore seems to exist in s...

Chapter
Biochemical Findings in Serum of Patients with Congestive Cardiomyopathy: Is Serum Selenium Concentration a Possible Marker?
The conventional methods of clinical chemistry, such as determination of enzyme activities in serum, are not suited for diagnosis or differential diagnosis of cardiomyopathy. Only in a few cases have we observ...

Ätiologie kardialer Rhythmusstörungen
Wie häufig ventrikuläre Herzrhythmusstörungen beobachtet werden, wird im wesentlichen durch die Dauer und Art der EKG-Registrierung bestimmt.

Vulnerability of the right ventricle to cathodal, anodal, and bipolar stimulation at double diastolic threshold strength
The repetitive ventricular response (RVR) to three stimulation techniques (bipolar, cathodal and anodal) was investigated in 35 patients. 26 patients suffered from coronary heart disease and 9 patients from di...

Liefern Konzentrationsbestimmungen von Nitraten im Serum Informationen für ihren therapeutischen Einsatz?
Für Pharmaka mit reversibler Wirkung läßt sich der pharmakologische Effekt mit Hilfe von Konzentrations-Wirkungsbeziehungen beschreiben. Häufig gelingt es einen sogenannten therapeutischen Konzentrationsbereic...

Prevalence of ventricular arrhythmias during silent myocardial ischemia
Symptomatic ST depression at rest and during exercise, as well as the occurrence of ventricular arrhythmias, are known to be independent risk factors in patients with coronary artery disease (1–4). However, th...

Calcium Antagonists in Silent Myocardial Ischemia — Preliminary Results with Nisoldipine
The use of calcium channel blockers was shown to be effective in the treatment of symptomatic and, more recently, of asymptomatic myocardial ischemia. In this continuing study we evaluated the efficacy of niso...

Mechanical balloon catheter recanalization combined with intracoronary lysis and PTCA
In 127 patients with acute transmural myocardial infarction combined intra venous (iv) and intracoronary (ic) thrombolysis therapy with streptokinase was started. In still occluded vessels a mechanical recanal...

Acute and chronic changes of myocardial energetics in the mammalian and human heart
In earlier studies using papillary muscles of the rat left ventricle and highly sensitive thermopiles we demonstrated that the heat liberated per gram of myocardium per unit of developed tension-time integral ...

Influence of phosphodiesterase inhibition on myocardial energetics in dilative cardiomyopathy
The effects of inhibition of phosphodiesterase by enoximone on left ventricular haemodynamics and myocardial energetics were investigated in 10 patients with idiopathic dilative cardiomyopathy. After intraveno...
