Summary
Myocardial ischemia is the leading cause of ventricular tachycardia (VT) in this patient group. Ventricular tachycardia carries a significant mortality risk of 13.7%.
Area of Science:
- Cardiology
- Electrophysiology
- Internal Medicine
Background:
- Ventricular tachycardia (VT) is a critical arrhythmia requiring understanding of its causes and outcomes.
- Etiology and patient outcomes for VT vary across different populations.
Purpose of the Study:
- To investigate the etiological factors and clinical outcomes of ventricular tachycardia (VT) in a specific patient cohort.
- To identify the most frequent causes and associated mortality rates of VT.
Main Methods:
- A descriptive study was conducted at Aga Khan University Hospital from November 2002 to October 2003.
- 58 adult patients presenting with or developing ventricular tachycardia (VT) were included, excluding those with pacemakers or VT during electrophysiological testing.
- Etiological workup and outcome recording (death or discharge) were performed using a pre-designed proforma.
Main Results:
- Myocardial ischemia was the most common etiology (43.5%), followed by cardiomyopathy (23.2%).
- Among patients with myocardial ischemia, non-ST elevation myocardial infarction was most prevalent (76.6%).
- 50% of patients experienced hemodynamic instability requiring defibrillation, and the overall mortality rate for VT was 13.7%.
Conclusions:
- Myocardial ischemia is a primary driver of ventricular tachycardia (VT) in the studied population.
- Ventricular tachycardia (VT) is associated with a substantial mortality rate of 13.7%.
