Abstract :

BACKGROUND : Sustained Ventricular Tachycardia ( VT ) is one of the most life threatening arrhythmias presenting in emergency. Haemodynamic instability in such patients further increases the morbidity and mortality.

AIMS AND OBJECTIVES : To study the effect of haemodynamic instability on the final outcome of sustained VT patients presenting in emergency and to study the clinicoaetiological profile of such patients..

METHODS : A total of 63 patients of sustained ventricular tachycardia ( VT ) presenting in emergency were enrolled. These patients were divided in to haemodynamically stable and unstable groups and were observed for their clinicoaetiological profile and outcome.

RESULTS : Haemodynamic instability at presentation was present in 22 patients ( 55 % ) of sustained VT, presenting in emergency. Majority of these patients were males ( 68 %). Polymorphic VT was present in 10 patients ; out of these 10 patients , 9 patients ( 90% ) were haemodynamically unstable. Coronary artery disease ( CAD) was the most common aetiology of haemodynamic instability seen in 15 patients ( 41 % ). Decreased Left Ventricular ejection Fraction ( LVEF ) was seen in 19 patients( 86 %) of haemodynamic instability.

CONCLUSION : Haemodynamic instability in sustained VT increases the mortality in such patients. Decreased LVEF and polymorphic pattern of VT are associated with increased chances of haemodynamic instability. Coronary artery disease ( CAD) is most common aetiology of haemodynamic instability in patients of sustained VT.
