Research on the ergogenic effects of music athletic performance usually includes multiple antecedents simultaneously. Consequently, this study set out to isolate a single antecedent using highly controlled experiment. More specifically, aim was investigate effect pre-task, slow- and fast-tempo arousal, affective state, perceived exertion, anaerobic rowing by isolating tempo as sole intrinsic mu...

A 32-year-old Spanish man presented to hospital after a second episode of syncope immediately following exercise. On admission, his vitals signs were stable and he had a regular heart rate of 60 bpm. ECG and transthoracic echocardiogram were normal. He completed 15 min of a BRUCE protocol exercise test. One minute and ten seconds into recovery, he lost consciousness. His ECG demonstrated sinus ...

Background: An electroencephalogram (EEG) is an accepted method in neurophysiology with a wide application. Different types of brain rhythms indicate that simultaneous activity of the brain cortex neurons depend on the person’s mental state. Method: we have focus on reviewing the existing literature pertaining to changes of the brain’s bioelectrical activity that recorded from the ...

conclusions diagnosis of tachycardia-induced cardiomyopathy in children is important, since appropriate treatment improves the prognosis. every child with recurrent and persistent palpitation with the first episode of congestive heart failure should be evaluated for tachycardia- induced cardiomyopathy. introduction tachycardia-induced cardiomyopathy (tic) is a ventricular dysfunction secondary ...

Background/Objective The heart rate (HR) and metabolic (VO2) responses to treadmill running using the GlideTrak™ body weight support system have not been reported. The purpose of this study was to compare the submaximal and maximal HR and VO2 responses to normal-weight treadmill running (TMR) to treadmill running with body weight support provided by the GlideTrak™ (GTR). Methods Twenty partic...

BACKGROUND AND OBJECTIVES Amniotic fluid embolism is a rare occurrence; it has a sudden onset and high morbidity. The objective of this report was to present a case of amniotic fluid embolism in a primipara undergoing analgesia for vaginal delivery. CASE REPORT This is a 38-year old pregnant woman with amniotic sac ruptured, cervix with 5-cm dilation, complaining of severe pain; the patient was...

Temporary transvenous pacemakers were inserted in ten patients with acute myocardial infarction complicated by atrioventricubu (A-V) block. With return of sinus rhythm, the ventricular rate was intentionally increased above sinus rate by graded increases of the pacemaker rate and stimulus amplitude to a maximum of 120 beats/minute and to 12 milliamperes for each paced rate. Four patients had ve...

BACKGROUND The prognostic significance of heart rate (HR) and its relationship with beta-blocker use are controversial and have never been evaluated in resistant hypertension. METHODS In a prospective study, 528 patients with resistant hypertension had HR measured on clinical examination, electrocardiography (ECG), and during ambulatory blood pressure monitoring. Primary endpoints were a comp...

background: noise is one of the annoying agents in the environment and it is harmful agent in workplaces that its occurrence with work load, there are in many workstations. the aim of this study was to determine the combined effects of exposure to noise and work load on heart rate changes. methods: this cross-sectional study performed on 14 male students into climatic chamber in 2011.the mean ±...
