T-wave Alternans Dependency on T-wave Amplitude in Exercise Electrocardiographic Recordings
T-wave alternans (TWA), an electrophysiologic phenomenon which manifests as an everyother-beat alternation of the electrocardiographic (ECG) T-wave amplitude or shape, is generally associated to malignant ventricular arrhythmias and sudden cardiac death. TWA is usually identified with no adjustment for T-wave amplitude. However, a possible dependency of TWA on T-wave amplitude has been recently...
متن کاملT-wave amplitude changes.
Scenario: This electrocardiographic (ECG) rhythm strip was obtained from a 74-year-old man who arrived at the emergency department (ED) with expressive aphasia and right-sided weakness. Consistent with a transient ischemic attack (TIA), his symptoms lasted 30 minutes and had resolved just prior to hospital arrival. He had experienced similar episodes in the past month. A recent ultrasound estim...
متن کاملComparison of exercise tests and 24-hour ambulatory electrocardiographic monitoring in detection of ST-T changes.
Forty-seven subjects over the age of 40 years, with atypical praecordial symptoms and a normal resting electrocardiogram, were evaluated for early detection of ischaemic heart disease using the single two-step exercise test, the multistage bicycle ergometric test, and continuous 24-hour ambulatory electrocardiographic monitoring. In 40 of the 47 subjects the results of both the ergometric test ...
متن کاملMagnetocardiographic evaluation of nonarrhythmogenic flecainide-induced electrocardiographic T-wave inversion
Flecainide is used for pharmacological conversion of atrial fibrillation (AF), to maintain sinus rhythm in patients with paroxysmal AF and/or supraventricular tachycardia, or to prevent catecholaminergic polymorphic ventricular tachycardia (1, 2). However, flecainide has been shown to be proarrhythmic in vitro (3) and was associated with threefold increase in arrhythmic death in Cardiac Arrhyth...
متن کاملElectrocardiographic Changes after Anoxaemia and Exercise in Angina of Effort.
Significant changes in the four lead electrocardiogram occur in two-thirds of all cases with angina of effort. This investigation shows that anoxaemia or exercise causes a temporary abnormal change in the electrocardiogram and reduces the number of those with effort angina but with no electrocardiographic abnormality to about 18 per cent. Details of the Anoxacmia Test.-The subject reclines on a...
