“…Sustained VT occurred in 6–31% of patients in these early cohorts, 2,4,6–8 while VF occurred in 4–20% of patients. 2–7 Our rates of these life-threatening arrhythmias are also better than rates in contemporary cohorts: 4.3%–10.2% for VT/ventricular fibrillation combined, 12,14,20 2.6%–6% for VT 21–23 and 3.5–5.4% for ventricular fibrillation.…”

Objectives In patients with acute coronary syndrome (ACS), we sought to: 1) describe arrhythmias during hospitalization, 2) explore the association between arrhythmias and patient outcomes, and 3) explore predictors of the occurrence of arrhythmias. Methods In a prospective sub-study of the IMMEDIATE AIM study, we analyzed electrocardiographic (ECG) data from 278 patients with ACS. On emergency department admission, a Holter recorder was attached for continuous 12-lead ECG monitoring. Results Approximately 22% of patients had more than 50 premature ventricular contractions (PVCs) per hour. Non-sustained ventricular tachycardia (VT) occurred in 15% of patients. Very few patients (≤1%) had a malignant arrhythmia (sustained VT, asystole, torsade de pointes, or ventricular fibrillation). Only more than 50 PVCs/hour independently predicted an increased length of stay (p<.0001). No arrhythmias predicted mortality. Age greater than 65 years and a final diagnosis of acute myocardial infarction independently predicted more than 50 PVCs per hour (p=.0004). Conclusions Patients with ACS seem to have fewer serious arrhythmias today, which may have implications for the appropriate use of continuous ECG monitoring.

“…Twenty-two patients showed left or right bundle-branch block, and the mortality was 32 per cent. Right bundle-branch block was twice as common as left, and was associated with anterior infarction more frequently than posterior (Table I) (Julian, Valentine, and Miller, 1964;Meltzer and Kitchell, 1966;Stock, Goble, and Sloman, 1967). Ventricular fibrillation is thought to be common in patients with frequent ectopic beats, but this has not been our experience.…”

“…As soon as continuous monitoring or recording of arrhythmias was made available, it became obvious that these figures grossly underestimated the frequency of such arrhythmias. Current figures range from 74 to 95 percent of patients (3)(4)(5)(6)(7)(8)(9)(10). Ventricular arrhythmias are by far the commonest, ac counting for more than three-fourth of all rhythm disturbances.…”

Two developments at the beginning of this decade exerted a profound influence upon clinical management of acute myocardial infarction: the in troduction of closed-chest resuscitation with electric shock therapy for ven tricular fibrillation, and the availability of continuous monitoring of the electrocardiogram by means of the cathode-ray oscilloscope. As a result of this, the coronary care unit has become a standard facility for the treatment of myocardial infarction. I t should be recognized that the concept of thera peutic centers for patients with myocardial infarction encompasses a broad range of facilities available in such units (1). On the one end of the spectrum, one can place the comprehensive cardiology center, equipped to treat all as pects and complications of myocardial infarction, including the use of emer gency surgery and artificial pump-support. On the other end, is the small area in a hospital in which nurses can observe the patient's rhythm displayed upon the monitoring oscilloscope. The great majority of coronary care units ap proach the latter end of the spectrum-based primarily on the availability of electrocardiographic monitoring units. Thus, the role of such units is the identification, early recognition, treatment, and prevention of dangerous arrhythmias. The most common arrhythmias that are potentially life-threat ening are related to increased "irritability" of the ventricular myocardium. The purpose of this review is to examine the rationale for the therapy of ventricular arrhythmias in acute myocardial infarction-both the fundamen tal and practical considerations. INCIDENCE OF ARRHYTHMIASDuring the earlier era, when the diagnosis of arrhythmias was based on their occurrence during routine examination of the patient or during record ing of an electrocardiographic tracing, the incidence of arrhythmias was es timated to range between 9 and 27 percent, with an average of 18 percent
