Low atrial rhythm mimics myocardial infarction

Low atrial rhythm mimics myocardial infarction

Answer: 683 A 55-year-old male patient was admitted to an emergency department of a secondary care hospital with left forearm pain and numbness of fingers lasting for 6 h. He did not state any kind of chest pain and has not had any cardiac disease history and risk factors except smoking for 30 years. Electrocardiography (ECG) demonstrated negative P waves and ST-segment elevation in inferior le...

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...

Idioventricular Rhythm in Acute Myocardial Infarction

An ectopic ventricular rhythm (IVR) with a rate of 60 to 100/min was detected in 36 of 100 consecutive patients with acute myocardial infarction by constant monitoring of the electrocardiogram. This mechanism was not apparent clinically and was usually transient, lasting 4 to 30 beats. It was frequently associated with inferior myocardial infarction and usually occurred during sinus bradycardia...

Idioventricular rhythm complicating acute myocardial infarction.

The incidence, natural history, prognosis, and electrocardiographic characteristics of idioventricular rhythm complicating acute myocardial infarction are described. It occurred as a transient arrhythmia nearly always within 24 hours of infarction in 61 (8%) of 737 patients, and was characterized by paroxysms of between 6 and 20 beats with widened bizarre QRS complexes at a rate of between 60 a...
