Overview
Risk factors for the ventricular tachycardia as a cause of wide complex tachycardia include a history of prior myocardial infarction, a history of congestive heart failure, and a history of recent angina pectoris. These three historical features have positive predictive values for VT of > 95% in a small study, but sensitivities of 66%, 24%, and 24%, respectively. Wide complex tachycardia will be due to VT in 98% of cases if there's a history of structural heart disease. Only 7% of patients with SVT with aberrancy will have had a prior myocardial infarction (MI).
Risk Factors
Common risk factors associated with VT/ VF include:
- Prior history of hypertension
- Prior MI
- ST-segment changes at presentation
- Chronic obstructive pulmonary disease
- Alcohol consumption
- Preinfarction angina
- Anterior infarct location
- Complete coronary occlusion at the time of coronary angiography
- Common risk factors associated with VT/ VF after primary PCI include:[1]
- Lowerblood pressure
- Higher heart rate
- Poor coronary flow at the end of the procedure
- Incomplete resolution of ST elevation
Common risk factors for ventricular tachycardia include:[2][3][4]
