Cardiac arrhythmias health

THE PATIENT WITH HEART BLOCK. The patient receiving atropine for third-degree heart block is placed on a cardiac monitor during and after administration of the drug. The nurse watches the monitor for a change in pulse rate or rhythm. Tachycardia, other cardiac arrhythmias, or failure of the drug to increase the heart rate must be reported to the primary health care provider immediately because other dm or medical management may be necessary. 

CARD IAC ARRHYTH MI AS AN D DIZZIN ESS. Patients receiving a diuretic (particularly a loop or thiazide diuretic) and a digitalis glycoside concurrently require frequent monitoring of the pulse rate and rhythm because of the possibility of cardiac arrhythmias. Any significant changes in the pulse rate and rhythm are immediately reported to the primary health care provider.

Very little information is available regarding the health effects of 1,1-dichloroethane following inhalation exposure in humans or animals. 1,1-Dichloroethane was used in the past as an anesthetic at a pressure of 0.026 atm, which is approximately equivalent to a concentration of 105,000 mg/m (26,000 ppm) (Miller et al. 1965). This use was discontinued when it was discovered that this compound induced cardiac arrhythmias at anesthetic doses (Browning 1965).

Examination of the QT interval is an important part of studies of cardiac health because of its ability to indicate potentially fatal cardiac arrhythmias before they happen even though the causes of the arrhythmias are diverse. Due to this diversity and significant normal variations in the QT interval, there is no... 

The dark side of hydrofluoric acid is its toxicity and corrosiveness. Aqueous and anhydrous HF readily penetrate the skin, and, because of its locally anesthetizing effect, even in very small quantities can cause deep lesions and necroses [4, 5]. An additional health hazard is the systemic toxicity of fluoride ions, which interfere strongly with calcium metabolism. Resorption of HF by skin contact (from a contact area exceeding 160 cm ), inhalation, or ingestion leads to hypocalcemia with very serious consequences, for example cardiac arrhythmia. 

Heart disease is the leading cause of death in the United States and is responsible for approximately 870,000 deaths per year (1). Sudden cardiac death (SCD) is responsible for almost half of these deaths, claiming 350,000 to 400,000 lives per year (2). SCD is defined by the World Health Organization as death due to any cardiac disease that occurs out of hospital, in an emergency room, or a patient who is dead on arrival to a care facility. Of note, the death must occur within one hour after the onset of symptoms. The majority of SCD is likely arrhythmic in etiology. In women, up to 88% of sudden cardiac arrests may be due to arrhythmic causes (3). Of SCD due to cardiac arrhythmias, greater than 80% of events are due to ventricular tachycardia (VT) and ventricular fibrillation (VF), with the remainder due to bradyarrhythmias and asystole (4). Coronary artery disease (CAD), manifesting acutely as ischemic ventricular arrhythmias or chronically as scar-mediated...
