CYCLOPROPANE ANAeSTHESIA AND VENTRICULAR ARRHYTHMIAS

Factors Modifying Cyclopropane-Epinephrine Cardiac Arrhythmias

WE HAVE reported that the minimal cardiac arrhythmia due to epinephrine in cyclopropane-anesthetized dogs is a coupled, usually bigeminal rhythm which exhibits a remarkably constant interval between the normal and the abnormal beats. This arrhythmia is elicited only by the simultaneous presence of a sympathomimetic amine with cardiac actions and a critical systemic blood pressure, which is char...

Ventricular Arrhythmias.

Ventricular tachycardia (VT) is the most common form of wide complex tachycardia and is associated with a high mortality rate. Electrocardiographic analysis remains paramount in diagnosis and helps to direct therapy. Antiarrhythmic agents, although effective in reducing arrhythmia burden, have never demonstrated a mortality benefit. The implantable cardioverter-defibrillator aids not only in th...

Gillis, MD ABSRACT: Sex-specific differences in the epidemiology, pathophysiology, clinical presentation, clinical treatment, and clinical outcomes of atrial fibrillation (AF), sustained ventricular arrhythmias, and sudden cardiac death are recognized. Sex hormones cause differences in cardiac ele...
