The prognostic significance of terminal bradycardia is analysed in this study. Amongst 12,145 intrapartal directly recorded cardiotocograms, 135 heart rate curves free of deceleration (1.1%) were found with an abruptly occurring fetal bradycardia. The mean duration of bradycardia was 5.7 +/- 3.1 minutes, the mean heart rate during the phase of bradycardia was 86.2 +/- 9.9 beats/minute. A premat...

Honey containing grayanotoxin is called mad honey which found in Turkey, Japan, Brazil, Europe, North America and Nepal. Patients present with clinical manifestations like bradycardia, hypotension syncope. In this case report we a 27 years male who presented bradycardia first-degree heart block after consumption of only 10 grams honey.

Freezing, a characteristic pattern of defensive behavior elicited by fear, is associated with a decrease in the heart rate. Central mechanisms underlying fear bradycardia are poorly understood. The periaqueductal gray (PAG) in the midbrain is known to contribute to autonomic cardiovascular adjustments associated with various emotional behaviors observed during active or passive defense reaction...

To analyse factors likely to precipitate bradycardia, 27 preterm infants born at 32 weeks' gestation or less were studied on 89 occasions. Polygraphic recordings of electrocardiography, oxygen saturation, and respiratory effort were made. Subsequently, upper airway flow was measured by a mask and pressure transducer. In 605 episodes detected during initial recordings, time of onset of bradycard...

three cases who underwent surgery in different areas of the craniofacial region were reported with bradycardia developing intraoperatively during flap traction. many cases of the oculocardiac reflex during treatment of the orbital region have been reported in the literature. this manuscript recorded that reflex bradycardia can occur during traction or stretching of any structure innervated by t...

BACKGROUND In susceptible humans, vasodepressor reactions are induced by restriction of venous return (upright tilting) and administration of isoproterenol. Because paradoxic bradycardia is a major manifestation of vasodepressor reactions, and allowing for extrapolation between paradoxic bradycardia in rats and vasodepressor reactions, we examined whether adenosine receptors mediate the paradox...

Pulmonary embolism (PE) can present with a variety of electrocardiographic findings. Bradycardia is rare finding in acute PE, which typically manifests sinus tachycardia. PE might arise from the physiologic Bezold–Jarisch reflex, describes constellation bradycardia, peripheral vasodilation, and hypotension. We report case woman her 60s who was admitted initially for submassive found to have bra...

Although sinus bradycardia is a common abnormality seen in medical reports, the proper evaluation of sinus bradycardia is poorly understood by physicians. Recent data from heart rate epidemiologic and cohort studies has emerged regarding the risk stratification of sinus bradycardia, which may help insurers better underwrite this abnormality. In this review, an operational age-related heart rate...

proximity of the vagus nerve to a patent ductus arteriosus (pda) can cause traction or entrapment of vagus nerve during surgical closure of the in rare occasions. this can lead to a life threatening postoperative bradycardia. herein, we report a case of bradycardia caused by unexpected irritation of the vagal trunk by the end of operation. the patient was managed by re-opening the chest, lung r...
