Anasarca-mediated attenuation of the amplitude of electrocardiogram complexes: a description of a heretofore unrecognized phenomenon.
OBJECTIVES The relationship between the changes of weight (WT) and electrocardiogram (ECG) QRS amplitude in patients with anasarca (AN) was evaluated. BACKGROUND Attenuation of the ECG voltage occurs as the electrical current spreads from the epicardium to the body surface. The voltage registered is a function of the cardiac potentials, the electrical resistivities of the intervening tissues ...

متن کاملLow voltage electrocardiogram after acute myocardial infarction.
In a retrospective study of patients with acute myocardial infarction admitted to a coronary monitoring unit in 1971 12 per cent (39 patients) had low voltage electrocardiograms within 72 hours of admission. Of these, 7 patients (18%) died while in hospital and a further 9 (23%) died within one year of their infarction. Of the 23 patients who survived, 16 were severely incapacitated by their sy...
متن کاملLow-Voltage Electrocardiogram in Acute Myocardial lnfarction*
In a restrospective study of 304 patients with acute transmural myocardial infarction admitted to the coronary care unit, 22 percent (67 patients) exhibited low voltage on their electrocardiograms within 72 hours of admission. The course of hospitalization of these patients was compared with an equal number of consecutive patients with transmural infarctions and normal electrocardiographic volt...
متن کاملAnalysis of electrocardiogram in chronic obstructive pulmonary disease patients.
INTRODUCTION Chronic obstructive pulmonary disease is the fourth leading cause of mortality worldwide. It is defined as a persistent airflow limitation usually progressive and not fully reversible to treatment. The diagnosis of chronic obstructive pulmonary disease and severity of disease is confirmed by spirometry. Chronic obstructive pulmonary disease produces electrical changes in the heart ...
