bradycardia/obesity

A 45-year old morbidly obese man with diabetes and severe chest problem had sudden bradycardia and sinus arrest in the Recovery Ward after an uneventful spinal anaesthesia. He responded promptly to "attempts" at external cardiac message with each thump producing a QTS complex until Atropine could be

Male Sprague-Dawley rats fed a condensed milk diet were classified as either "obesity susceptible" (OS) or "obesity resistant" (OR) based on body weight increases attained after 12 wk. Overall caloric intake in OS rats was higher than in chow-fed controls, and OS rats were heavier than chow-fed

A 74-year-old morbidly obese man was scheduled for surgical repair of an incisional ventral hernia. Anaesthesia was induced with propofol and fentanyl, and maintained with desflurane. A second dose of fentanyl 0.2 mg, given before starting surgery, resulted in sinus bradycardia and mild decrease of

Serious maternal bradycardia and asystole in laboring parturients after combined spinal-epidural labor analgesia are rare. We report such a case in a morbidly obese laboring parturient after receiving combined spinal-epidural labor analgesia. The differential diagnosis, risk factors, potential

BACKGROUND The symptomatic sick sinus syndrome presents a classic indication for the implantation of a dual-chamber pacemaker according to the current national and international guidelines. However, in cases where dizziness and near syncope due to a sinus node dysfunction are found together with

BACKGROUND Obesity, apneic hypoxemia, and rapid eye movement (REM) sleep are supposed to be the major causes for bradyarrhythmia in patients with obstructive sleep apnea. The aims of this study were to compare clinical findings and diagnoses in patients with obstructive sleep apnea with and without

A 52-year-old man with myxedema was evaluated for anterior chest pain that was considered to be compatible with myocardial ischemia. The night after admission he developed extreme bradycardia, hypotension, and apneic episodes lasting up to 25 s. Continuous positive airway pressure and administration

Obstructive sleep apnoea (OSAS) affects 4% of men and 2% of women aged 30-65 years. It is diagnosed in the presence of excessive daytime sleepiness and an apnoea-hypopnoea index (AHI) of ≥5 on polysomnography. Rhythm disturbances are common in OSAS and continuous positive airway pressure (CPAP) has

We compared reflex chronotropic responses to intravenously infused drugs in three groups of age-matched normotensive female rats, namely, Sprague-Dawley, lean Zucker, and obese Zucker. Initial mean pressures did not differ between rat groups, but heart rates tended to be lower in obese Zucker rats.

OBJECTIVE There is a reciprocal relationship between sleep duration and weight gain. However, the consequences of this relationship on the cardiovascular system over an entire life span are still not fully elucidated. We examined the effect of acute sleep deprivation (SD) on baroreflex sensitivity

Cardiovascular dysfunction associated with obesity was assessed by comparing rats that had been maintained on a regular or high fat diet since weaning. Rats on the high fat diet not only gained weight faster than age-matched controls but also had higher systolic and mean pressures. Development of

Adult obese Zucker rats (OZR; >12 wk) develop elevated sympathetic nerve activity (SNA) and mean arterial pressure (MAP) with impaired baroreflexes compared with adult lean Zucker rats (LZR) and juvenile OZR (6-7 wk). In adult OZR, baroreceptor afferent nerves respond normally to changes in MAP,

Exercise training (ET) has been established as an important treatment for obesity, since it counteracts aberrant cardiac metabolism and weight gain; however, underlying mechanisms remain to be further determined. MicroRNAs (miRNAs) inhibit protein expression by base-pairing with the 3' UTRs of mRNA

The autonomic responsiveness of lean women to standing, passsive vertical tilting, noradrenaline infusion and the valsalva manoeuvre has been compared with that of obese women and a group of formerly obese women (post-obese). Upon standing, the lean and obese groups had comparable cardiovascular
