Acid-base imbalance and arrhythmias after myocardial infarction.

Myocardial infarction and atrial arrhythmias.

ATRIAL ARRHYTHMIAS occur in about 10 per cent of acute myocardial infaretions and the commonest of these arrhythmias is atrial fibrillation.' When atrial fibrillation is sustained after beginning during myocardial infarction, it has been reported to be associated with an 89 per cent mortality.2 Although there have been a number of studies on the clinical aspects of the association of such rhyth...

Left ventricular remodeling and ventricular arrhythmias after myocardial infarction.

BACKGROUND The relation between left ventricular (LV) remodeling and ventricular arrhythmias after myocardial infarction is poorly documented. We investigated the relations between LV size, hypertrophy, and function and ventricular arrhythmias in 263 patients from the Survival and Ventricular Enlargement (SAVE) study, using quantitative 2D echocardiography and ambulatory ECG monitoring after my...

Arrhythmias in Acute Myocardial Infarction.

Cardiac arrhythmias during myocardial infarction.

A 58-year-old man, who had used cocaine and other illicit drugs in the past, had mild, intermittent exertional chest discomfort for 2 weeks followed by severe, prolonged chest pain, which began while he was dancing and was unrelieved by rest. An electrocardiogram recorded on arrival at the emergency department (Figure 1) showed acute inferoposterior myocardial infarction with some features of r...

The Wedensky test predicts malignant ventricular arrhythmias after myocardial infarction

OBJECTIVES Better tools are needed for detection of future malignant ventricular arrhythmias post myocardial infarct (MI). Wedensky Modulation (WM) is a new semi-invasive method: A short low-amplitude electrical impulse is applied synchronized to the QRS between a precordial and dorsal thoracic patch, and changes in the following QRS-T are registered. DESIGN A total of 357 (MI) ICD patients u...
