introduction: purpose of this study was the effect of different music rhythms (fast rhythm and slow rhythm) in physiological responses of health young male after an exhaustive exercise session during primary minutes of recovery period. methods: seventeen healthy male (ages: 19.76 ± 0.97 yr, height: 176 ± 6.72 cm, weight: 68.5 ±7 5.95 kg), voluntarily performed bruce protocol until exhaustion wi...

Cardiac tamponade is associated with decreased cardiac output and increased systemic vascular resistance. Thus, vasodilator drugs might lower systemic resistance and increase cardiac output. Three groups of dogs were studied during tamponade. Group I received nitroprusside only; group II received blood transfusion and then nitroprusside; group III received hydralazine. In group I, nitroprusside...

The role of Pharmacist in making the therapeutic decisions for safe and effective therapy is increasing all over the world. However, there are many aspects of drugs in making these decisions that are less commonly studied such as the correlation of cardiac output with pharmacokinetics of drugs. The cardiac output, besides the other factors, is also affected by drugs like atenolol. Therefore, th...

Continuous monitoring of stroke volume (SV) or cardiac output (CO) has long been the subject of numerous studies. The majority of existing methods are calibration-dependent, requiring invasive measurements of CO to initialize the estimation algorithms, thus limiting their application to the clinical setting. In the present study, a new calibration-free method aimed at home-based use has been de...

SINCE THE INITIAL observations of William Harvey and the physiologic studies of Ernest Starling, the importance of changes in volume in the ventricles of the heart has been recognized. In physiologic and clinical studies of the heart, measurements of chamber pressure and cardiac output have been more easily obtained than volume, and only in recent years have methods been developed for the estim...
