Beta-adrenergic blockade and cardiac arrhythmias.
The evaluation of beta-adrenergic blockade in cardiac arrhythmias is difficult because of the complex nature of the arrhythmias and the varied modes of action of blocking drugs. Studies have confirmed the therapeutic value of the betaadrenergic blocking drug pronethalol (Alderlin) (Vaughan Williams, 1963 ; Stock and Dale, 1963 ; Payne and Senfield, 1964; Wolfson et al., 1966) and its more poten...
متن کاملSuppression of ventricular arrhythmias in man by d-propranolol independent of beta-adrenergic receptor blockade.
To investigate the mechanisms of ventricular arrhythmia suppression by propranolol, we determined the antiarrhythmic efficacy of d-propranolol in 10 patients with frequent ventricular ectopic depolarizations (VEDs) and nonsustained ventricular tachycardia. After an initial placebo phase, 40 mg d-propranolol was administered orally every 6 h with dosage increased every 2 d until arrhythmia suppr...
متن کاملCardiac output after beta-adrenergic blockade in ischaemic heart disease.
The suggestion that blockade of the cardiac sympathetic nerves might be helpful in patients with angina pectoris has received some experimental support (Apthorp, Chamberlain, and Hayward, 1964; Hamer et al., 1964). The increased myocardial contractility during exercise is produced by stimulation of beta-adrenergic sympathetic fibres (Ahlquist, 1948) which are specifically blocked by pronethalol...

متن کاملEffect of chronic beta-adrenergic receptor blockade in congestive cardiomyopathy.
Adrenergic beta-blocking agents were given to 7 patients with advanced congestive cardiomyopathy who had tachycardia at rest (98 plus or minus 13 beats/min). The patients were on beta-adrenergic receptor blockade for 2 to 12 months (average 5-4 months). One patient was given alprenolol 50 mg twice daily and the other patients were given practolol 50 to 400 mg twice daily. Virus infection had oc...
