Cardiac 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...
متن کاملSYMPOSIUM Cardiac Arrhythmias (Part 2) Hemodynamic Sequelae of Cardiac Arrhythmias
The hemodynamic consequences of cardiac arrhythmias depend on various factors, including the ventricular rate and the duration of the abnormal rate, the temporal relationship between atrial and ventricular activity, the sequence of ventricular activation, the functional state of the heart, the irregularity of the cycle length, associated drug therapy, the peripheral vascular vasomotor system, d...
