Multiform ventricular ectopic rhythm. Evidence for multiple parasystolic activity.

Multiform Ventricular Ectopic Rhythm

Six patients whose standard electrocardiograms showed multiform ventricular ectopic rhythm were studied. All patients had advanced organic heart disease and a significant intraventricular conduction defect (left bundle branch block in five and right bundle branch block plus left anterior hemiblock in one). The ventricular arrhythmia was generally resistant to antiarrhythmic therapy. Five of the...

Ventricular Parasystolic Tachycardia.

Ventricular tachycardia like ventricular parasystole is rarely observed in the absence of cardiac disease (Massie and Walsh, 1960; Scherf and Bornemann, 1961), though several cases of functional ventricular tachycardia without demonstrable heart disease have been reported by Hair, Eagan, and Orgain (1962) and others. Parasystole consists of simultaneous activity of two independent impulse-formi...

Ventricular ectopic activity in hemodialysis.

C. Quereda, MD, Servicio de Nefrología, Centro Ramón Cajal, Carretera de Colmenar km 9,100, 28034 Madrid (España) Dear Sir, In an interesting study recently published in Nephron , Wizemann et al. [1] concluded that the incidence of ventricular arrhythmias in chronic hemodialysis (HD) patients is primarily dependent on the presence of preexisting coronary artery disease and that HD or related me...

Ectopic Rhythm

CHEST I 93 I 3 I MARCH, 1988 647 In summary, we report the first patient with bilateral pneumothoraces, bilateral empyemas and baeteremia resuiting from the common practice of illicit drug injection into the internal jugular veins. Needle marks in the supraclavicular area in dyspneic patients suspected of intravenous drug abuse should alert physicians to the possibility of these potentially lif...
