results according to the studies reviewed, induction of mild hypothermia in patients after cardiopulmonary resuscitation would lead to increased survival and better neurological outcome; however, studies on the complications of hypothermia or different methods of inducing hypothermia were limited and needed to be studied further. conclusions this study provides strategic issues concerning the i...

a 67-year-old male suffering from depressive symptomatology was admitted to the inpatient clinic at firat university school of medicine; and his psychiatric evaluation revealed major depressive episode according to dsm-iv. he developed chest discomfort, chest pain and shortness of breath of acute onset accompanying pulseless ventricular tachycardia (vt) leading to cardiac arrest following sertr...

Sick sinus syndrome is an abnormality involving the generation of the action potential by the sinus node and is characterized by an atrial rate inappropriate for physiological requirements. Manifestations include severe sinus bradycardia, sinus pauses or arrest, sinus node exit block, chronic atrial tachyarrhythmias, alternating periods of atrial bradyarrhythmias and tachyarrhythmias, and inapp...

Twenty-four children and young adults with electrocardiographic evidence of sinus node dysfunction (SND) are described. The patients, whose ages ranged from three days to 25 years, were divided into three groups based on the type of SND. Ten patients had persistent and inappropriate sinus bradycardia (group I): twelve patients had episodes of prolonged sinus arrest (group II); and seven patient...

Cardioplegic arrest for bypass surgery imposes global ischemia on the myocardium, which generates oxyradicals and depletes myocardial high-energy phosphates. The glycolytic metabolite pyruvate, but not its reduced congener lactate, increases phosphorylation potential and detoxifies oxyradicals in ischemic and postischemic myocardium. This study tested the hypothesis that pyruvate mitigates oxid...

The reversibility of verapamil-induced hemodynamic and electrophysiologic changes by intravenously administered CaCI2 and NaCI was tested in 34 anesthetized open-chest dogs during verapamil infusions which produced plasma verapamil concentrations of 70-2042 ng/ml. An increase of serum calcium concentration (Ca). to an average 6.5 mEq/l abolished the depressive effects of verapamil on cardiac ou...

Reflex bradycardia and sinus arrest may occur in a variety of surgical procedures, from neurosurgery to general abdominal, laparoscopic, ophthalmic and facial surgery and even procedures such as liver biopsies and electroconvulsive therapy. In most cases a vagally-mediated reflex has been implicated, although experimental support for this is often lacking. Drugs such as vecuronium, atracurium, ...

Reported herein is a coronary anomaly that occurred in a young adolescent athlete who presented with cardiopulmonary arrest. The patient was resuscitated and treated with therapeutic hypothermia. The patient had no associated neurological complications at follow up. Enhanced computed tomography of the heart indicated an anomalous left main coronary artery originating from the right coronary sin...

An hour after a 220 V electric shock a patient who was susceptible to mild vasovagal symptoms in response to emotional stress had a severe episode of cardiac arrest in response to insertion of a cannula. No myocardial damage or conduction abnormalities were detected by serial 12 lead electrocardiograms. Patients with a history of vasovagal reactions may be at high risk of developing lethal sinu...

Mycotic pseudoaneurysm of the ascending aorta is rare in patients undergoing coronary artery bypass graft (CABG) and usually caused by staphylococcus aureus. We describe a patient with a mycotic pseudoaneurysm of the ascending aorta at the proximal vein graft anastomosis site after CABG. Culture from the sinus tract of the sternum and from the aneurysm sac was Klebsiella pneumoniae. Surgical te...
