Premature beats and unexpected heart block: an unusual mechanism confirmed by ablation.
A 23-year-old, otherwise healthy woman presented with recurrent skipped and rapid sustained heart beats. Her physical examination and echocardiogram were normal. The presenting ECG in Figure 1 shows sinus rhythm, a nonconducted sinus p wave, and premature complexes. Both left bundle-branch block (5 and 6 complexes) and right bundlebranch block (10 complex) morphologies are present. The 5 and 10...

متن کاملModulation of extracellular atrioventricular node field potential pattern and ventricular rhythm by morphine in experimental atrial fibrillation in isolated rabbit heart
Introduction: Endorphins are produced by cardiomyocytes, and exert different effects on the heart. The aim of the present study is to assess morphine effects on extracellular atrioventricular (AV) node field potential pattern and ventricular rhythm of isolated rabbit heart during experimental atrial fibrillation (AF). Methods: Effects of different concentrations of morphine (10, 20, 50 and 1...
متن کاملNew manifestations of electrophysiological remodeling of heart during experimental model of atrial fibrillation in cirrhotic rat isolated heart
Introduction: The present study is aimed to evaluate electrophysiological remodeling of atrioventricular (AV) node and ventricular conduction during experimental atrial fibrillation (AF) model in isolated heart of cirrhotic rats. Methods: Cirrhosis-induced electrophysiological remodeling was evaluated in 24 isolated retrogradely perfused rat hearts in 2 groups (control and cirrhotic). Cirrho...
متن کاملLimitation of tachycardia zone resulting from longitudinal dissociation of the atrioventricular node in concealed pre-excitation.
Two cases with a concealed left-sided accessory atrioventricular bypass tract are described. In both, functional longitudinal dissociation of the atrioventricular node narrowed the range of atrial premature beat coupling intervals which could initiate re-entry using the accessory pathway. In case 1 early premature atrial beats were followed by an atrioventricular nodal re-entrant echo. The atri...
