BRIEF REVIEW Histamine and Cardiac Arrhythmias
Modification of the cardiac rhythm by histamine has been appreciated almost since the compound's isolation from ergot by Barger and Dale in 1910. The major arrhythmogenic actions of histamine are an Hi-receptor-mediated slowing of atriovenrricular (AV) conduction and H2-receptor-mediated increases in sinus rate and ventricular automaticity. These actions were elucidated by observing the salutar...
متن کاملCaffeine and cardiac arrhythmias: a review of the evidence.
Limited data exist on the safety and physiologic effects of caffeine in patients with known arrhythmias. The studies presented suggest that in most patients with known or suspected arrhythmia, caffeine in moderate doses is well tolerated and there is therefore no reason to restrict ingestion of caffeine. A review of the literature is presented.
متن کاملCardiac arrhythmias.
Disorders of cardiac rate and rhythm represent major causes of mortality and morbidity in developed countries. Sudden cardiac death, defined as death within 1 hour of an unexpected change in cardiovascular status, kills more than 300,000 people each year in the United States (29), whereas nonlethal arrhythmias account for much additional disability. Atrial fibrillation, a leading cause of cereb...
متن کاملCardiac Arrhythmias
Cardiac arrhythmias are disturbances in the rhythm of the heart, manifested by irregularity or by abnormally fast rates (tachycardias) or abnormally slow rates (bradycardias). Patients who perceive these abnormalities most frequently observe palpitations,which somedescribe as the sensation of ‘my heart turning over in my chest’, or awareness that their hearts are beating rapidly or slowly. Othe...
