[Treatment with ubiquinone in Kearns-Sayre syndrome. Improvement in ocular motility and visual evoked potentials].

In 1985 Ogasahara observed that treatment with ubiquinone produced improvement in the cardiac conduction and the metabolism of the lactic and pyruvic acids in the Kearns-Sayre syndrome. The results of the administration of 150 mg/day of ubiquinone for 3 years in a patient diagnosed with the Kearns-Sayre syndrome is described. The patient improved notably in strength, ocular movement, visual evoked potentials and in the metabolism of lactic and pyruvic acids. Other beneficial effects reported in the literature have been improvement of ataxia and the somato-sensitive evoked potentials. No side effects have been described.

A randomized, double-blind, placebo-controlled study of verapamil and metoprolol in treatment of multifocal atrial tachycardia.

PURPOSE: Multifocal atrial tachycardia is a difficult arrhythmia to treat. Patients not showing a response to the correction of predisposing conditions present a therapeutic dilemma. To assess the efficacy of two agents reported to be effective in this condition, verapamil, metoprolol, or placebo was given intravenously in a randomized, double-blind trial. PATIENTS AND METHODS: Thirteen patients meeting inclusionary criteria were enrolled. Therapeutic response was defined as conversion to sinus rhythm, a decline in the ventricular rate of 15 percent or more [corrected], or a ventricular rate of less than 100 beats/minute. Four male and nine female patients having a mean age (+/- SD) of 81.9 +/- 14.2 years were enrolled. Automated serum chemistries, complete blood cell count with differential, arterial blood gas values, and serum digoxin and theophylline levels were determined and a 12-lead electrocardiogram was obtained at the start of the trial. Following the completion of each phase of the study, a repeat physical examination was performed, and arterial blood gas values and an electrocardiogram were obtained. The trial was designed to run for two days. RESULTS: Two of 10 (20 percent), four of nine (44 percent), and eight of nine (89 percent) showed a response to placebo, verapamil, or metoprolol, respectively. Mean slowing of ventricular rate was 3.4, 7.3, and 24.5 percent for placebo, verapamil, and metoprolol, respectively (p less than 0.01 for metoprolol versus placebo). Five patients who showed a response to metoprolol had failed to have a response to verapamil. CONCLUSION: We conclude that metoprolol appears to be more effective than verapamil in treating multifocal atrial tachycardia. However, careful patient selection is necessary in its use.

Metoprolol in the treatment of multifocal atrial tachycardia.

Multifocal atrial tachycardia (MAT) is a difficult arrhythmia to treat. Pharmacologic treatment is generally disappointing, and successful conversion in a predictable manner is uncommon. To assess the efficacy of metoprolol, a relatively selective beta 1-adrenergic blocking agent, we administered this agent to 11 patients (aged 71.8 +/- 8.3 yr). All patients had serious pulmonary disease. Hypoxia, hypercarbia, acidosis, and electrolyte abnormalities were corrected before the study. Nine patients were receiving theophylline derivatives and six digoxin. Serum levels for both drugs were in the therapeutic range. Four patients had received verapamil without control of MAT. Mean atrial rate before administration of metoprolol was 142.3 +/- 17.2 beat/min and mean ventricular rate was 131.4 +/- 24.3 beat/min. One to 3 h after metoprolol (25 or 50 mg orally), all patients were restored to sinus rhythm, with a mean ventricular rate of 86.9 +/- 6.8 beat/min (p less than .01). Six patients had 3 to 6 premature atrial contractions per minute. No adverse effects were noted, and arterial blood gases before and after therapy were comparable. Five patients expired from their underlying disease and four were continued on metoprolol to maintain sinus rhythm. Metoprolol is effective in the acute and chronic treatment of MAT and may be given to patients with MAT and respiratory failure without serious adverse effects.

Treatment of severe left ventricular dysfunction with calcium chloride in patients receiving verapamil.

This report describes two patients who received verapamil because of supraventricular arrhythmias. The patients both developed severe hypotension and signs of left ventricular compromise. The hypotension and left ventricular compromise were promptly reversed by administration of intravenous calcium chloride. The dramatic improvement was documented clinically and in one case by two-dimensional echocardiography.
