Chatterjee phenomenon in a patient with heart failure with preserved ejection fraction: a case report

نویسندگان

چکیده

The article presents a case report of the Chatterjee phenomenon after implantation pacemaker in patient with heart failure preserved ejection fraction. During hospitalization specialized cardiology hospital, patient's electrocardiogram (ECG) showed atrial fibrillation (AF) ventricular rate 49 bpm, ST segment depression 1 mm I, II, V4-V6 leads. Taking into account data 24-hour ECG monitoring (pauses up to 5,2 seconds AF) and Stokes-Adams syndrome equivalents, decision was made implant single-chamber pacemaker. Immediately implantation, AF registered on VVI mode 60 pulses/min. On second day intervention, reprogrammed form reducing minimum pacing from 45 third altered terminal complex part detected negative T waves III, aVF, V2-V6 leads, as well V3-V6 1,5 mm. Differential diagnosis identified abnormalities other clinical conditions accompanied by impaired repolarization processes according carried out. In dynamics, normalization picture 2,5 months demonstrated.

Heart Failure With Preserved Ejection Fraction

Symptomatic heart failure, despite preserved left ventricular (LV) ejection fraction, is a well-recognized phenomenon. This manifestation of diastolic dysfunction is associated with increased morbidity and mortality and can be attributed to a variety of pathogeneses, including diabetes mellitus, hypertension, infiltrative processes, and obesity. Unlike in systolic heart failure, where LV ejecti...
