Name of the test | Results |
---|---|
Holter ECG | Sinus rhythm, mean HR 85/min with numerous single extrasystole (over 3,000 excitations), 20 episodes of ventricular tachycardia |
Heart USG | Decreased global heart muscle contractility with a decline of ejection fraction. No akinesis or other features characteristic of ischemia |
Sympathetic skin response | No responses to auditory or electrical stimulation |
RR interval variation test (RRIV) | Abnormal, with HRV decreased at rest-ranged from 3.99-5.78 as well as during deep breathing (5.91%), without.an increase in HRV on hyperventilation |
SFEMG from right external digitorum communis muscle (SF-EMG) | Mean jitter value increased to 53 us (norm 32+/−5.7), in 4 pairs above 55 useconds |
