the aim of this study was to investigate the effect of external intervention factor (types of music) on physical fitness factors in adolescent boys. 30 adolescent boys (9-12 years old, msd height, weight and bmi: 133.82.40 cm, 35.62.97 kg, and 19.91.21 kg/cm2), were selected and performed the tests in three stages (fast music, slow music, control) with counter balance method. in each stage, the...

In the present study, we investigated a hypothesized quartic relationship (meaning three inflection points) between exercise heart rate (HR) and preferred music tempo. Initial theoretical predictions suggested a positive linear relationship (Iwanaga, 1995a, 1995b); however, recent experimental work has shown that as exercise HR increases, step changes and plateaus that punctuate the profile of ...

INTRODUCTION Children and young adults require a higher maximum tracking rate (MTR) for physical activity. The objective of the present study was to observe whether higher MTR of 170 or 190 beats per minute (bpm) have a positive impact on the maximal cardiorespiratory capacity of children and young adults in comparison with a lower MTR of 140 bpm. METHODS Fifteen patients with atrioventricula...

Case report A 48-year-old man with nonischemic dilated cardiomyopathy, left ventricular ejection fraction r35% status post dual-chamber ICD (Boston Scientific Energen, model E142) since September 2012, history of ventricular tachycardia with antitachycardia pacing (ATP) therapy, paroxysmal atrial fibrillation, and atrial tachycardia on beta-blocker therapy was seen in clinic following an ICD sh...

BACKGROUND In patients with chronic heart failure (CHF) and conduction delay, biventricular (BiV) and left ventricular (LV) pacing similarly improve systolic function at resting heart rates. We hypothesized that BiV and univentricular pacing differentially affect contractile function at increasing heart rates. METHODS AND RESULTS Twenty-two patients (aged 66+/-2 years, QRS 179+/-8 ms, LV ejec...

Neuronal population oscillations at a variety of frequencies can be readily seen in electroencephalographic (EEG) as well as local field potential recordings in many different species. Although these brain rhythms have been studied for many years, the methods for identifying discrete oscillatory epochs are still widely variable across studies. The "better oscillation detection" (BOSC) method ap...

Case report An 82-year-old Caucasian female patient, who had a history of hypertension, dual-chamber pacer implantation for paroxysmal atrial fibrillation, and sick sinus syndrome 3 years ago, was transferred from an outside hospital for evaluation and management of a wide complex tachycardia at 115 beats per minute (bpm). Her home medications included candesartan-hydrochlorothiazide (32/12.5 m...

This patient has an arrhythmia with orthodromic circus movement tachycardia and dual AV-nodal pathways. In addition, the ECG shows a Brugada pattern. The resting ECG (Fig. 1a) shows sinus rhythm and a type 2 Brugada pattern. The 12-lead ECG during arrhythmia (Fig. 1b) shows a narrow QRS rhythm, 88 bpm (cycle length: 680 ms) with a 1:1 AV ratio. The P waves are narrow and inverted in leads II, I...

This paperwork presents the design and test of a microcontroller-based ECG (electrocardiogram) simulator. The ECG simulator is capable of generating nine ECG signals and a calibrated square wave (1 Hz, 1 mV at Lead II). The synthesized signals are: normal sinus rhythm (60 beats per minute – BPM, and 90 BPM), sinus bradycardia (30 BPM), sinus tachycardia (120, 180 and 240 BPM), sinus rhythm with...
