Primary study design	Interventional
Study design	Randomised controlled trial
Secondary study design	Randomised controlled trial
Scientific title
Study acronym	MAVERIC
Study objectives	The optimal way to manage patients who present with sustained ventricular tachycardia (VT), ventricular fibrillation (VF) or sudden cardiac death (SCD), especially in the context of comparing the traditional approach of empirical amiodarone against electrophysiology-guided interventions, which include myocardial revsacularisation, programmed ventricular stimulation and the implantable cardioverter-defibrillator (ICD).
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Cardiovascular diseases: Heart disease
Intervention	Electrophysiology + implantable cardioverter defibrillators (ICDs) versus Amiodarone empirically
Intervention type	Other
Primary outcome measure(s)	1. Death 2. Arrhythmia recurrence 3. Hospitalisation 4. Drug use 5. Quality of life 6. Cost of managing patients
Key secondary outcome measure(s)	Not provided at time of registration
Completion date	30/11/1999

Participant type(s)	Patient
Age group	Adult
Sex	All
Target sample size at registration	214
Key inclusion criteria	1. Patients who presented with sustained ventricular tachycardia (VT), ventricular fibrillation (VF) or sudden cardiac death (SCD) and survived to reach hospital within the Midlands from Feb 1997 to Jan 1999 were actively identified and entered into the study. 2. Patients who were not of child-bearing age or had a life-expectancy of <6 months from a non-arrhythmic cause were approached for entry into the trial. Patients who were ineligible for or refused to join the trial were entered into the study's registry.
Key exclusion criteria	Does not match inclusion criteria
Date of first enrolment	01/11/1996
