The purpose of the study is to assess prospectively at 6 months the percentage of responder patients implanted with a Cardiac Resynchronization Therapy (CRT-D) device and a Quartet Left Ve...
The primary intent of this study is to assess the safety of the model 1457Q Quartet Left Ventricular (LV) lead at 3 months in a patient population indicated for cardiac resynchronization t...
This study is designed to show that a new lead, which paces the left bottom chamber (left ventricle) of the heart, is safe. Using a lead on the left side of the heart has been shown to pot...
Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. When there are ch...
People who have abnormal heart beats, or whose heart does not beat on its own, may need an electronic device called a pacemaker or a defibrillator. Furthermore, people whose hearts have a...
Inadvertent malpositioning of a cardiac implantable electronic device lead into the left ventricle is a rare complication of transvenous pacing and defibrillation. Rapid identification of lead positio...
ICD lead failure is a potential source of significant morbidity and mortality. This study investigates the survival rates of Sprint Quattro, Endotak Reliance and Linox ICD leads.
Major complication rate of transvenous lead extraction (TLE) is estimated around 1-2.0%. Laceration of the central veins can be fatal.
Subcutaneous implantable cardioverter defibrillator in patients awaiting cardiac transplantation or left ventricular assist device for refractory heart failure: a feasible alternative to transvenous device?
Over the years, the aVR lead has been overlooked by clinicians while observing a normal 12-lead ECG (electrocardiogram). A positive P-QRS complex in the aVR lead should raise prompt suspicion for eith...
Injury to the nervous system secondary to exposure to lead compounds. Two distinct clinical patterns occur in children (LEAD POISONING, NERVOUS SYSTEM, CHILDHOOD) and adults (LEAD POISONING, NERVOUS SYSTEM, ADULT). In children, lead poisoning typically produces an encephalopathy. In adults, exposure to toxic levels of lead is associated with a peripheral neuropathy.
Neurologic disorders occurring in children following lead exposure. The most frequent manifestation of childhood lead toxicity is an encephalopathy associated with chronic ingestion of lead that usually presents between the ages of 1 and 3 years. Clinical manifestations include behavioral changes followed by lethargy; CONVULSIONS; HALLUCINATIONS; DELIRIUM; ATAXIA; and vomiting. Elevated intracranial pressure (HYPERTENSION, INTRACRANIAL) and CEREBRAL EDEMA may occur. (From Adams et al., Principles of Neurology, 6th ed, p1210-2)
Neurologic conditions in adults associated with acute or chronic exposure to lead or any of its salts. The most common lead related neurologic syndrome in adults consists of a polyneuropathy involving motor fibers. This tends to affect distal nerves and may present as wrist drop due to RADIAL NEUROPATHY. Additional features of chronic lead exposure include ANEMIA; CONSTIPATION; colicky abdominal pain; a bluish lead line of the gums; interstitial nephritis (NEPHRITIS, INTERSTITIAL); and saturnine gout. An encephalopathy may rarely occur. (From Adams et al., Principles of Neurology, 6th ed, p1212)
Poisoning that results from chronic or acute ingestion, injection, inhalation, or skin absorption of LEAD or lead compounds.
Unstable isotopes of lead that decay or disintegrate emitting radiation. Pb atoms with atomic weights 194-203, 205, and 209-214 are radioactive lead isotopes.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
