The most recent improvement of biomedical signal processing, information technology and communication has brought a new measurement to the medical world. It is now possible to record an ECG signal with a convenient electrocardiograph trivial and able to convert a micro-computer in electrocardiograph with the possibility of a diagnostic aid for automatic analysis. At the present changing from a ...

Clinical manifestations of digitalis toxicity were clearly described by Withering in 1785. One hundred years later, certain digitalis-induced arrhythmias were inscribed on the smoked drum, and shortly thereafter with the introduction of the electrocardiograph, manifestations of digitalis toxicity as recognized today were recorded in animals and human beings. With popularization of the direct-wr...

The effects of hypertension on resting and reflex cardiovascular function were investigated in this study.  Blood pressure, heart rate and electrocardiogram were recorded in male and female control subjects and hypertensive Nigerian patients.  Blood pressure was measured, using the sphygmomanometer/auscultatory method.  Heart rate was determined from palpating the radial pulse or from the resti...

PURPOSE To review and evaluate the potential cardiac effects of 5-HT(3) antiemetic treatment in patients who may be predisposed to cardiac complications resulting from malignancy, cytotoxic oncologic regimens, or preexisting comorbid conditions. DESIGN A literature review was conducted on the negative cardiovascular effects of chemotherapeutic agents, and, more specifically, on the cardiac in...

BACKGROUND An aortic-to-radial arterial pressure gradient may develop during and after cardiopulmonary bypass (CPB). The mechanisms of this pressure gradient remain controversial. To clarify the cause of the pressure gradient after CPB, the authors investigated the relationship between the pressure gradient and changes in the pulse wave velocity (PWV) before and after CPB. METHODS The pressur...

The use of the Electrocardiograph in diagnosis is that it gives us an additional mode of examination whereby to supplement the clinical methods we were taught as students and are still learning as practitioners. It is its conjunction with clinical findings that gives electrocardiography its peculiar charm. Lewis"' has written that "Electrocardiography is the last court of appeal and its judgmen...

INTRODUCTION Myocardial injury is one of the most notorious complications of a hypertensive crisis. Key electrocardiograph signs used to detect cardiac injury such as ST segment changes and cardiac arrhythmias usually indicate acute ongoing end-organ damage. Lack of early signs to predict end-organ damage might lead to a delay in the initiation of therapy and selection of the incorrect therapeu...

Based on data from Basic Health Research (Riskesdas) in 2018, the incidence of heart and blood vessel disease is increasing year to year. At least 15 out 1000 people or about 2,784,064 individuals Indonesia suffer disease. Therefore, cardiovascular health care can make a better diagnosis through continuous monitoring. The purpose this study was develop 12-lead circuit, lead selector (Wilson Cen...
