[Cardiac arrhythmia and myocardial contraction in opium and ephedrone addiction].
Sixty-two patients with opium and ephedrone abuse were studied. They underwent 24-hour Holter monitoring, resting ECG and echocardiography, 18 of them having volumetric loading with polyglucine, 400.0 ml, i.v. Sinus tachycardia was detected in 67.4%, ventricular extrasystole in 4.7%, supraventricular extrasystole with infrequent paroxysms of supraventricular tachycardia in 11.6%. Despite the fact that signs of heart failure were absent and myocardial contractility was normal at rest, echocardiography along with volume loading allow one to reveal in patients some abnormal contractile alterations in the left ventricle. These include its increased volumes, decreased ejection fraction and circulatory shortening rate of myocardial fibers, which suggests that the compensatory potentials of the myocardium are reduced in drug abuse.
