Right ventricular abnormalities in ventricular tachycardia of right ventricular origin: relation to electrophysiological abnormalities.
Why the study?
Does echocardiographic assessment of right ventricular structure correlate with electrophysiological abnormalities in patients with right ventricular tachycardia?
Population

Implication
RV dilatation on echo signals higher-risk RV tachycardia; leaves open whether it should guide management or risk stratification.
Structured PICO
Does echocardiographic assessment of right ventricular structure correlate with electrophysiological abnormalities in patients with right ventricular tachycardia?
P
Population
17 patients presenting with right ventricular tachycardia without coronary artery disease or gross abnormalities of left ventricular function.
I
Intervention
Echocardiography and electrophysiological study
C
Comparator
Patients with normal right ventricular dimensions (Group 1) versus patients with right ventricular dilatation (Group 2)
O
Outcome
Right ventricular structural abnormalities and their relation to electrophysiological featuressurrogate
Echocardiographic identification of right ventricular structural abnormalities correlates with more severe electrophysiological features in patients with right ventricular tachycardia.
