Sinus Bradycardia

Posted by syra on 25 Jan 2011 at 10:59 GMT

One of the most common causes of pathologic sinus bradycardia is symptomatic sick sinus syndrome.
The most common drugs are responsible for the therapeutic and supratherapeutic doses of digitalis glycosides, beta-blockers and calcium channel blockers. Other heart medications less frequently involved include Class I antiarrhythmic drugs and amiodarone. A wide variety of other drugs and toxins have been reported to cause bradycardia, including lithium, paclitaxel, toluene, dimethyl sulfoxide, acetylcholine ophthalmic, fentanyl, alfentanil, sufentanil, reserpine and clonidine. Sinus bradycardia can be seen in hypothermia, hypoglycemia and sleep apnea. Less commonly, the sinus node may be affected as a result of diphtheria, rheumatic fever or viral myocarditis. http://www.insideheart.co...
