The widespread application of automatic external defibrillators (AEDs) for treating out-of-hospital cardiac arrest incidents and their particular use at railway stations defines the task for 16.67 Hz power line interference elimination from the electrocardiogram (ECG). Although this problem exists only in five European countries, it has to be solved in all AEDs, which must comply with the European standard for medical equipment requirements for interchangeability and compatibility between rail systems. The elimination of the railroad interference requires a specific approach, since its frequency band overlaps with a significant part of the frequencies in the QRS spectra...

During cesarean section under regional anesthesia various anomalies of the electrocardiogram are reported such as bradycardia, supraventricular and ventricular premature beats, supraventricular paroxysmal tachicardia, S-T depression non-significant for myocardial ischemia and second degree atrioventricular block. We describe two cases of accelerated idioventricular rhythm in patients undergoing elective cesarean section with spinal anesthesia of which we have not found mention in the literature. This arrhythmia is not dangerous and does not usually evolve into ventricular fibrillation...

UNLABELLED: Ventricular fibrillation and ventricular tachicardia without pulse are the most frequent causes of suddenly death, therefore, it was considered that training hospitals and healthcentre nurses in identifying arritms and using properly the defibrilators was necessary. It was made by practical-theoric courses. The main aim of this study has been to know does the nurses value these type of courses and its repercussion on their level of knowledge. This is a descriptive study. The course consisted of 2 parts, one theoric and other practical...

BACKGROUND: In recent years port-access and endovascular extra-corporeal circulation techniques have allowed valvular and coronary operations to be performed by mini-thoracotomy. Experience with the technique suggested application to resection of ventricular aneurysms, which are usually approached through a median sternotomy with the use of traditional cardiopulmonary bypass. METHODS: We performed a left port-access mini-thoracotomy, with 6 to 8 cm skin incisions, in 7 patients undergoing endoventricular pericardial patch repair for anterior left ventricular aneurysm...

Carboxyperitoneum and traditional forced ventilation of the lungs have a negative impact on external respiration function during laparoscopic operations, leading to impairment of the ventilation device, pressure rise in airways, and decrease in oxygen diffusion and carbon dioxide release. This leads to accumulation of carbon dioxide in the blood and tissue with a trend to development of acidosis of mixed origin. Cardiovascular changes during laparoscopic cholecystectomy manifest by hypertension and tachicardia in the presence of increased central venous pressure and total peripheral vascular resistance, decreased stroke and cardiac indexes, decreased right-ventricular diastolic function, increased pressure in the pulmonary artery, and deceleration of venous bloodflow in the inferior and superior venae cavae...

A group was formed of patients presenting with electrical instability of myocardium (those persons manifesting induction of ventricular tachicardia, ventricular fibrillation) after performing programmed stimulation of ventricles of the heart in 63 patients suffering from myocardial infarction and unstable angina pectoris. The main noninvasive markers of electrical instability were shown to be postinfarction cardiosclerosis, circulatory insufficiency, evolution of acute aneurysm of the heart. Institution of differentiated therapy involving correction of circulatory insufficiency with capoten, low doses of beta-blockers, specified use of antiarrhythmic drugs tailored to the individual, employing electrophysiologic testing, make it possible to improve the intrahospital diagnosis in myocardial infarction and select a group of patients to be surgically tested...

With the aid of intracavitary electrophysiological investigation in hospital the influence of ethmosin, an antiarrhythmic agent, on the function of atrio-ventricular conducting system was studied in 52 patients with paroxysmal supraventricular tachicardias. It was established that the drug depresses significantly the electrophysiological values of Kent's bundle, the His-Purkinje system and atrioventricular node (mainly in the retrograde conduction): and also prolongs considerably the time of the intra-atrial conduction...

The present study has been carried out on 50 patients admitted to C.C.U. for cardiovascular diseases of various ethiology (44 patients with ischemic heart disease) who required antiarrhythmic theory for different types of ventricular arrhythmias: monofocal ventricular extrasistoles greater than 6/min, bigeminal ventricular extrasistoles, polifocal and/or repetitive ventricular tachycardias. The patients have been randomly allocated into two groups of 25 subjects: the first one has been treated with Mexiletine and the second with Lidocaine...

Suppression of aconitine-induced ventricular tachycardia in the dog with various doses of Bunaftine was attempted. Stable re-establishment of the sinus rhythm was achieved in only 3/15 cases, whereas in 3 tachicardia was unchanged, and in 9 fibrillation appeared, due, it is thought, to the effect of the drug on myocardial conductivity, since fibrillation was the most frequent outcome when high doses were used.

Pericarditis may complicate the early phase of myocardial infarction (MI). It occurs when necrosis involves the epicardial surface. To verify if pericarditis may be regarded as a marker of extensive MI, 60 patients with anterior or inferior MI admitted to the Coronary Care Unit within 6 hours from onset of symptoms, were studied by clinical, electrocardiographic and enzymatic parameters. 20 patients developed left ventricular failure (LVF) assessed by clinical, radiologic and hemodynamic indexes (15 mmHg has been considered the upper normal value for mean wedge pulmonary pressure)...

The effects of amiodarone (2.5 mg/Kg i.v.) and of verapamil (0.1 mg/Kg i.v.) on refractory periods and on conduction of structures interested in the reciprocating circuit, as well as on the possible echo zones, were comparatively evaluated through electrophysiological test in 8 patients, four of which with W.P.W. from Kent bundle, and four with double A-V pass with reciprocating supraventricular tachicardia (RST) documented crises. None of the two drugs seems to have the theorical requirements of balanced effect to be chosen for the antiarrhythmic prophylaxis in patients with ventricular pre-excitement...
