متن کاملStress Testing During Cardiac Catheterization: Exercise and Pacing Tachycardia
Patients with significant heart disease may have entirely normal hemodynamics when assessed in the resting state during cardiac catheterization. Because most cardiac symptoms are precipitated by exertion or some other stress, however, it also may be important to assess hemodynamic performance during some form of stress such as muscular exercise, pharmacologic intervention (e.g., dobutamine infu...
متن کاملVentricular tachycardia during exercise testing as a predictor of sudden death in patients with chronic chagasic cardiomyopathy and ventricular arrhythmias.
OBJECTIVE To verify the prognostic value of exercise induced ventricular arrhythmias in patients with chagasic cardiomyopathy. METHODS 69 consecutive patients (37 male, 32 female; age range 21-67 years) with chronic chagasic cardiomyopathy and ventricular arrhythmias (more than 10 ventricular premature complexes per hour) were evaluated during treadmill exercise testing, using the Bruce proto...
متن کاملTrazodone-related exercise-induced nonsustained ventricular tachycardia.
A 79-year-old woman in the course of a syncope evaluation is shown to have a trazodone-related cardiac arrhythmia confirmed by drug rechallenge. This nontricyclic antidepressant should be considered as potentially arrhythmogenic despite its generally favorable cardiovascular profile.
متن کاملGitelman's syndrome with exercise-induced ventricular tachycardia.
A 62-year-old female with palpitations was admitted to hospital where she recorded 12,299 monofocal ventricular premature contractions (VPCs) in 24 h and nonsustained ventricular tachycardia (VT) on exertion. She had hypokalemia with renal potassium wasting, a chloride-resistant metabolic alkalosis, elevated plasma renin, elevated plasma aldosterone (relative to the serum K concentration), hypo...
