The elderly patient in the coronary care unit. II. Incidence and treatment of arrhythmias.
In 1976, 130 patients aged 70 or older were admitted to the Coronary Care Unit (CCU) at Toronto Western Hospital. Arrhythmias were noted in all but 24 percent. Digoxin was given to 53 patients, lidocaine to 24, propranolol to 28, and quinidine to 11. In 2 patients, cardioversion by direct current was required for supraventricular arrhythmias. In 26 patients, temporary pacemakers were used. Of 13 patients who experienced at least one cardiac arrest in the CCU, 10 survived to be discharged to the ward. In total, only 12 of the 130 elderly patients died in the hospital, and in only 3 of these was arrhythmia the primary cause of death. The treatment of arrhythmias in the elderly is as successful and rewarding as in younger patients. Indications for the various antiarrhythmic drugs are similar. Except for digoxin, the dosages of such drugs for the elderly are the same as those for younger patients. Adverse effects apparently are not more common in the elderly.
