Ventricular Arrhythmias.
Ventricular tachycardia (VT) is the most common form of wide complex tachycardia and is associated with a high mortality rate. Electrocardiographic analysis remains paramount in diagnosis and helps to direct therapy. Antiarrhythmic agents, although effective in reducing arrhythmia burden, have never demonstrated a mortality benefit. The implantable cardioverter-defibrillator aids not only in th...
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...
متن کاملManagement of common arrhythmias: Part II. Ventricular arrhythmias and arrhythmias in special populations.
In patients without established cardiac disease, the occurrence of premature ventricular complexes without sustained ventricular tachycardia is more an annoyance than a medical risk, and treatment is not required. In contrast, patients with established heart disease and premature ventricular complexes have a higher likelihood of developing ventricular tachycardia or fibrillation. These patients...
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...
